Abstract

A new spirophenylacridine (SPA) derivative, SPA-SO2, was synthesized via full bridging of sulfone, carbonyl, and oxygen to the SPA core. Using its precursor molecule SPA-S as a reference, the two molecules were systematically characterized, including single crystal structures, electrochemical properties, and photophysical properties. Notably, SPA-SO2 exhibits a blue shift and narrowing of spectra compared to SPA-S. Theoretical investigations provided mechanistic insights, suggesting that bridging modifications can precisely modulate molecular properties by altering the electronic structure. Finally, SPA-SO2 was applied in electroluminescence devices, exhibiting deep blue emission at 436 nm and achieving a maximum external quantum efficiency of 9.4%. This work introduces a bridging modification strategy for SPA, contributing to advancements in optoelectronic materials.

一种新型全桥接螺苯吖啶衍生物的合成与表征

通过砜、羰基和氧在SPA核心上的全桥接，合成了一种新的spirophenyl吖啶（SPA）衍生物SPA- so2。以其前体分子SPA-S为参照物，对两种分子进行了系统表征，包括单晶结构、电化学性质和光物理性质。值得注意的是，与SPA-S相比，SPA-SO2表现出蓝移和光谱变窄。理论研究提供了机理上的见解，表明桥接修饰可以通过改变电子结构来精确地调节分子性质。最后，将SPA-SO2应用于电致发光器件中，在436 nm处表现出深蓝色发射，最大外量子效率为9.4%。这项工作介绍了一种桥接改性策略的SPA，有助于光电子材料的进步。
