单体结构单元的组装可以显示新特性的显示,包括光学,机械和电化学功能。在这项研究中,我们试图开发一种功能性的荧光团自组装体,该团簇仅在聚集时才能产生活性氧。由于蒽与荧光素部分之间的分子间相互作用较弱,因此带有蒽亚苯基(AP)基团的带负电荷和中性的荧光素单元在水溶液中形成非荧光H-聚集体。与之形成鲜明对比的是,硼二吡咯亚甲基(BODIPY)和AP二聚体通过在富电子的蒽与缺电子的BODIPY部分之间形成分子间电荷转移(CT)复合物而产生双色发射聚集体。此外,令我们惊讶的是,1 O 2)和激发时的光细胞毒性,表明BODIPY-蒽CT状态有利于系统间杂交。根据X射线晶体学分析,确定了BODIPY和AP部分之间的晶格状分子堆积,以实现空前的聚集诱导1 O 2生成(AISG)。

interesting fluorescence properties and have the potential to be developed into bimodal photoredoxcatalysts. One has been confirmed to be an photoredoxcatalyst in the reactions of N‐aryl‐tetrahydroisoquinolines with phosphite, nitromethane, malonitrile and sodium thiocyanate, led to 22%‐95% yields. The catalyst capabilities remain with recyclable using under the reaction conditions.
A dramatic improvement of our previous methodology based on a Suzuki-Miyaura cross-coupling to access 3,3'-disubstituted H-8-BINOLs using microwave heating is reported herein. These new conditions represent a large gain in term of atom-economy, reaction time, catalyst loading, and excess of reagents employed. (C) 2014 Elsevier Ltd. All rights reserved.
