Red Emissive(红色发射)研究综述
Red Emissive 红色发射 - HJS and DHJS, two near-infrared emissive and mitochondria-targeted therapy probes, have been designed. [1] By combining them with red emissive carbon dots (quantum yield of 17. [2] Low-energy excited states decay efficiently non-radiatively, so that near-infrared emissive transition metal complexes with 3d transition metals are even more challenging. [3] 61%), and it was chosen to coat a UV LED-chip (λem = 400 nm ± 10 nm) to fabricate a red emissive LED-prototype; also, a prototype with a blend between powdered Eu-complex and cyanoacrylate glue was fabricated, and their emission behavior and radiant photostability were compared. [4] The acquired emissive fingerprint powder gave superior images with high distinction and resolution connecting the ridges and space. [5] In this work, red emissive CDs (R-CDs) with a quantum yield as high as 66. [6] The prepared emissive microgel and light-harvesting system with desirable fluorescent property not only provide a new strategy for the fabrication of tunable luminescent nanomaterials, but also expand potential applications in the fields of stomach recognition, temperature sensors, and drug delivery. [7] Herein, a kind of red emissive carbon dots (R-CDs) was synthesized from methylene blue (M. [8] In this work, two far-red emissive fluorescent turn-on probes (KXS-M1 and KXS-M2) for the highly selective and sensitive detection of MAO-A were fabricated. [9] By taking advantage of their excellent optical properties, the CD powers, combined with red emissive europium metal-organic frameworks, are successfully employed as hybrid phosphors for construction of white light-emitting diodes exhibiting a Commission Internationale de L’Eclairage (CIE) coordinate of (0. [10] By performing systematic purification and characterization, we reveal the presence of a molecular fluorophore, quinoxalino[2,3-b]phenazine-2,3-diamine (QXPDA), in a large amount (∼80% of the total mass) in red emissive CNDs synthesized from o-phenylenediamine (OPDA), which is one of the well-known precursor molecules used for CND synthesis. [11] Herein, we developed one kind of red emissive two-photon carbon dots (TP-CDs) via an N doping strategy for nucleolus-targeted treatment combined with real-time monitoring of dynamic changes in the nucleolus. [12] Besides, the plume infrared emissive energy mainly concentrates in a special wavenumber interval and can be strongly absorbed by atmosphere. [13] The unique probe can form near-infrared emissive aggregates (∼670 nm) in mitochondria with high ΔΨm, which turned to green-emitting monomers (530 nm) with loss of ΔΨm. [14] Herein, blue, green and red emissive carbon dots were synthesized from the different ratio of o-phenylenediamine and catechol by the solvothermal method. [15] Red emissive carbon dots (CDs) powder was synthesized on a large scale from phloroglucinol and boric acid by a novel solid state reaction with yield up to 75%. [16] The fabrication of a red to near-infrared emissive molecules in aggregated states is very important for bioimaging. [17] However, the inability to obtain pixelated random laser arrays with highly ordered emissive geometries hinders the application of flexible laser displays in the wearable device. [18] By applying laser pulses, infrared emissive patterns are directly encoded into an ultrathin (∼25 nm) Ge2Sb2Te5 layer integrated into a planar optical cavity with the optically crystallized Ge2Sb2Te5 spots, and the peak spectral emissivity is repeatedly switched between low (∼0. [19] A sensitive and turn-on fluorescence nanoprobe based on core-shell [email protected] nanoparticles ([email protected]) as a fluorescence receptor and red emissive graphene quantum dots (GQDs) as a donor was fabricated. [20] Owing to the pre-built state of QD aggregation, there has been aggregation-enhanced fluorescence resonant energy transfer (AE-FRET) from a blue emissive QD aggregate donor to a red emissive DL acceptor in the internal of the QD-DL probe. [21] Based on DFT/TDDFT calculations and analysis of the X-ray crystal structures, the origin of the different phosphorescences has been ascribed to H-aggregation of the ligand (in 1-Ag and 2-Ag), intermolecular electronic coupling by an extrinsic heavy-atom effect (in 1-Ag) and ligand-centered emissive states (in all three compounds). [22] Results NIR-CDs with good mono-dispersity and hydrophily were easily prepared by a one-step microwave-assisted carbonization manner, which showed obvious UV absorptive and far-red emissive properties. [23] Furthermore, we observed for the first time a DNA-AgNC population (as part of the DNA811-AgNC sample) with green and near-infrared emissive states with nanosecond and microsecond decay times, respectively. [24] Blue, green, yellow, red emissive films, and LEDs are prepared by dispersing the corresponding CDs into polyvinyl alcohol (PVA). [25] These deep-red emissive nanostructures (638 nm excitation, ≈700 nm emission) are stabilized by proteins in cell medium. [26] Overall, this work shows a rational approach to design fluorophore–metal configurations with the desired emissive properties and a basis for a useful nanophotonic technology under biological conditions. [27] In our system, N-doped carbon dots (N-CDs), a kind of green and red emissive CDs, were loaded or embedded onto the PDA NPs for fluorescent imaging. [28] Here, it is found that the addition of varied metal ions during the hydrothermal treatment of p-phenylenediamine (pPDA) leads to the formation of red emissive CDs with QYs varying from 1. [29] A highly selective and red emissive fluorescent probe (HCyNB) for penicillin G amidase (PGA) has been prepared in a simple two-step process. [30] In this work, a near-infrared emissive dipyridyl ligand was synthesized and used to prepare three platinum(II) metallacycles with different shapes via metal-coordination-driven self-assembly with different platinum(II) precursors. [31] Our experimental results showed that the use of red emissive PQDCF achieved an EQE of 20%. [32] The CDs contain blue, green, and red emissive centers produced from catechol, o-phenylenediamine, and their complexes, respectively. [33] These "TOP" nanosensors are based on 100 nm-sized silica-coated polystyrene nanoparticles (PS-NPs) doped with a near-infrared emissive oxygen- and temperature-sensitive chromium(III) complex ([Cr(ddpd)2][BPh4]3, CrBPh4) and an inert reference dye (Nile Red, NR or 5,10,15,20-tetrakis(pentafluorophenyl) porphyrin, TFPP) and are covalently labeled with pH-sensitive fluorescein isothiocyanate (FITC). [34] The new hybrid system is a deep-red emissive material (phosphorescence maximum at ca. [35] Furthermore, this easy-to-use CsPbBr3-PSZ film can be employed to realize a remote-type white-by-blue LED by combining it with red emissive K2SiF6:Mn4+/silicone film. [36] A series of monochromatic PHOLEDs with different phosphorescent dopants, including blue emissive FIrpic, green emissive Ir(ppy)2(acac) and red emissive Ir(piq)2(acac) are fabricated by employing these four host materials. [37] The UV-vis spectra of these red emissive BTD-based bolaamphiphiles covered almost the whole visible range with a relatively low band gap. [38] On excitation, these particles showed a strong emission at 605 nm which corresponds to 4G5/2 → 6H7/2 transition and other emissions at 563 nm and 647nm correspond to 4G5/2 → 6H5/2 and 4G5/2 → 6H5/2 transitions revealing that it is an orange-red emissive phosphor. [39] A red emissive fluorescent probe 1,7-dimethyl-3,5-bis(4-methoxyphenyl-vinyl)-8-(10-n-butyl-10H-phenothiazine-3-yl)BODIPY 1,7-dimethyl-3,5-bis(4-methoxyphenyl-vinyl)-8-(10-n-butyl-10H-phenothiazine-3-yl)BODIPY (avyl-BODIPY-PTZ) with a special orthogonal donor-acceptor structure was designed and synthesized for rapid, sensitive, and selective discrimination of ClO−, over other reactive oxygen species and anions. [40] In view of the few reports of the near-infrared emissive probe for fluorine ions, we herein designed and synthesized a new easy-to-get colorimetric and near-infrared emissive fluorescent probe (IS-NR-F) with a large Stokes shift (>127 nm). [41] Near-infrared emissive carbon dots (CDs) were synthesized by hydrothermal method. [42]HJS 和 DHJS 是两种近红外发射和线粒体靶向治疗探针，已被设计出来。 [1] 通过将它们与红色发射碳点结合（量子产率为 17.

aggregation induced emission
The weakly emissive L in DMSO turned to red emissive L with the increase in the poor solvent fraction in DMSO because of the combined effects of the aggregation-induced emission (AIE) and excited-state intramolecular proton-transfer (ESIPT). [1] This study suggests a simple and highly efficient method for the enhancement of the growth and lipid productivity of microalgae by using deep-red emissive light-converting films with aggregation-induced emission. [2] Herein, we report the design and synthesis of a highly near-infrared emissive organic nanodots with aggregation-induced emission (AIE) characteristic, which give excellent performance in seeing the fate and regenerative mechanism of adipose-derived stem cells (ADSCs) in treatment of radiation-induced skin injury. [3] To overcome the ACQ effect and to enhance the overall efficacy of PDT, herein, integrin ανβ3-targeted organic nanodots for image-guided PDT were designed and synthesized based on a red emissive aggregation-induced emission (AIE) PS. [4]由于聚集诱导发射 (AIE) 和激发态分子内质子转移 (ESIPT) 的共同作用，DMSO 中的弱发光 L 随着 DMSO 中不良溶剂分数的增加而转变为红色发光 L。 [1] 本研究提出了一种简单高效的方法，通过使用具有聚集诱导发射的深红色发射光转换膜来提高微藻的生长和脂质生产力。 [2] nan [3] nan [4]
