Abstract

A new family of aggregation-induced emission (AIE)-active monoboron and bisboron complexes based on benzothiazole-hydrazone chelates was synthesized. These complexes showed very weak fluorescence in fluid solution due to active intramolecular rotation and were emissive in high-viscosity solvents or in the aggregation state. Single crystal X-ray diffraction analyses and theoretical calculations were carried out to explain AIE behavior. The large Stokes shifts (3590-7400 cm-1) and relatively highly efficient solid-state emission make these complexes valuable AIE luminophores for further potential applications.

摘要

合成了一种新型基于苯并噻唑-腙螯合物的聚集诱导发光（AIE）活性单硼和双硼配合物。这些配合物在流体溶液中由于分子内旋转的活性而显示出非常弱的荧光，并且在高粘度溶剂或聚集状态下具有发光性。通过单晶 X 射线衍射分析和理论计算解释了 AIE 行为。大斯托克斯位移（3590-7400 cm-1）和相对高效的固态发射使这些配合物成为有价值的 AIE 发光体，可进一步潜在应用。
