Abstract

Non-ESIPT C-HBTP and ESIPT C-HBTO were designed and synthesized through nickel-catalyzed cross-coupling reactions, utilizing o-carborane and 2-(2′-hydroxy-phenyl)benzothiazole (HBT) as substrates. The photophysical characteristics of these compounds were thoroughly investigated through UV-vis absorption spectroscopy, fluorescence spectroscopy, and DFT calculations. C-HBTO, with its ESIPT properties, undergoes a structural transformation from an enol structure to a more stable ketone configuration. Additionally, C-HBTP and C-HBTO exhibited excellent aggregation-induced emission (AIE) properties and good quantum yields of 39.1% and 33.8% in the solid state, respectively.

ESIPT 调制的 HBT 邻硼烷二元体具有高效的聚集诱导发射和酸诱导变色特性

以邻硼烷和 2-(2′-羟基苯基)苯并噻唑 (HBT) 为底物，通过镍催化交叉偶联反应设计并合成了非 ESIPT C-HBTP 和 ESIPT C-HBTO。通过紫外可见吸收光谱、荧光光谱和 DFT 计算，对这些化合物的光物理特性进行了深入研究。具有 ESIPT 特性的 C-HBTO 经历了从烯醇结构到更稳定的酮构型的结构转变。此外，C-HBTP 和 C-HBTO 还具有出色的聚集诱导发射（AIE）特性，在固态下的量子产率分别为 39.1%和 33.8%。
