color and efficiency. Notably, the cyclopentane-fused arsole showed aggregation-caused quenching (ACQ) in the solid state, while cyclohexane and cycloheptane offered aggregation-induced emission enhancement (AIEE). This trend was also seen in heterocycle-fused arsoles; five- and six-membered rings offered ACQ and AIEE, respectively. The p-(dimethylamino)phenyl and p-(dimesitylboryl)phenyl groups at the
本研究合成了多种 1,2,5-triaryl-3,4-cycloalka[ c ]arsoles 以控制发光颜色和效率。亚硝基中心和 2,5-位芳基之间的扭转取决于稠合环
烷烃的大小,从而导致不同的吸收最大值。此外,结构松弛受到稠合环
烷烃的影响,从而改变了发光颜色和效率。值得注意的是,
环戊烷稠合的阿苏尔在固态下表现出聚集引起的猝灭(A
CQ),而
环己烷和
环庚烷则提供聚集诱导的发射增强(AIEE)。这种趋势也出现在杂环融合的 arsoles 中;五元环和六元环分别提供 A
CQ 和 AIEE。p- (二甲基
氨基)苯基和p由于电荷转移特性,2,5-位的-(二亚甲基
硼基)苯基显示出红移发射,它们可以分别检测质子和
氟阴离子等离子。
