Conjugated Macrocycles(共轭大环)研究综述
Conjugated Macrocycles 共轭大环 - Three-dimensional aromaticity arising from the close stacking of two antiaromatic π-conjugated macrocycles has recently received considerable attention. [1] π-Conjugated macrocycles are molecules with unique properties that are increasingly exploited for applications and the question of whether they can sustain global aromatic or antiaromatic ring currents is particularly intriguing. [2] In this work, a linear polymeric porphyrin with "structure defects" was developed to overcome the ACQ effect for most of the photosensitizers with conjugated macrocycles. [3] The study indicates that to attain 3D global aromaticity in a molecular cage, all the formally available π-conjugated macrocycles should be 2D aromatic. [4] By changing the condensation partner as the linking unit, a family of conjugated macrocycles with different sizes of the cavity was synthesized, which provide a simple and modular synthetic strategy towards the conformationally adaptive macrocycles. [5] π-Conjugated macrocycles are molecules with unique properties that are increasingly exploited for applications and the question of whether they can sustain global aromatic or antiaromatic ring currents is particularly intriguing. [6] Here, we found that conjugated macrocycles, 3B2A and 4B2A, could function as donors encapsulating electron-deficient fullerene to form a molecular-scale p–n junction, which enables fast electron transfer and enhanced exciton dissociation for current rectification. [7] Conclusions: The study offers interesting insights into the tuneability of the properties of this versatile class of π-conjugated macrocycles. [8] Two kinds of π-conjugated macrocycles with aggregation-induced emission (AIE) properties were investigated by scanning tunneling microscopy (STM) to elucidate their self-assembly behaviors and interaction with C60 on a highly oriented pyrolytic graphite (HOPG) surface. [9] For conjugated macrocycles, conformational disorder plays a key role in determining whether the unique form of excitons that are fully delocalized over the cyclic framework (cyclic excitons) is formed by photoexcitation. [10] We report the template-free synthesis and characterization of a new type of porphyrin/quinoidal bithiophene based conjugated macrocycles. [11] Cyclobis[n]helicenes (n = 3 or 5) are chiral D2-symmetric π-conjugated macrocycles with stable lemniscular, or figure-eight, shapes. [12] This Account describes a body of research on the design, synthesis, and application of a new class of electronic materials made from conjugated macrocycles. [13] Angle-strained alkyne-containing π-conjugated macrocycles are attractive compounds both in functional materials chemistry and biochemistry. [14]由两个反芳族 π 共轭大环的紧密堆积产生的三维芳香性最近受到了相当大的关注。 [1] π-共轭大环是具有独特性质的分子，越来越多地用于应用，它们是否能够维持全局芳香环或反芳香环电流的问题特别有趣。 [2] 在这项工作中，开发了一种具有“结构缺陷”的线性聚合物卟啉，以克服大多数具有共轭大环光敏剂的 ACQ 效应。 [3] 该研究表明，要在分子笼中获得 3D 全局芳香性，所有正式可用的 π 共轭大环都应该是 2D 芳香性的。 [4] 通过改变缩合伙伴作为连接单元，合成了一系列具有不同空腔大小的共轭大环，为构象自适应大环提供了一种简单的模块化合成策略。 [5] π-共轭大环是具有独特性质的分子，越来越多地用于应用，它们是否能够维持全局芳香环或反芳香环电流的问题特别有趣。 [6] 在这里，我们发现共轭大环 3B2A 和 4B2A 可以作为供体包裹缺电子富勒烯以形成分子级 p-n 结，从而实现快速电子转移和增强激子解离以进行电流整流。 [7] 结论：该研究为这种多功能 π 共轭大环的性质的可调性提供了有趣的见解。 [8] 通过扫描隧道显微镜（STM）研究了两种具有聚集诱导发射（AIE）特性的π共轭大环，以阐明它们在高取向热解石墨（HOPG）表面上的自组装行为和与C60的相互作用。 [9] 对于共轭大环，构象无序在确定是否通过光激发形成在环状框架上完全离域的独特形式的激子（环状激子）方面起着关键作用。 [10] 我们报告了一种新型卟啉/醌式二噻吩基共轭大环化合物的无模板合成和表征。 [11] Cyclobis[n]helicenes (n = 3 or 5) 是手性 D2-对称 π-共轭大环，具有稳定的透镜状或八字形。 [12] 该帐户描述了对由共轭大环制成的一类新型电子材料的设计、合成和应用的研究。 [13] 角度应变的含炔烃 π 共轭大环化合物在功能材料化学和生物化学中都是有吸引力的化合物。 [14]
