zirconacyclopentadienes. The obtained peraryl arsoles showed aggregation‐induced emission (AIE), where intense emission was observed in the solid states (quantum yields up to 0.61), whereas the corresponding solutions were very weakly emissive. The optical and electronic properties were examined by experimental and computational methods. It was elucidated that the aryl groups at the 2,5‐positions affected
2,3,4,5-四芳基-1-苯基芳基醚是通过使用安全生成的二碘苯基s氨酸和氧化锆环戊二烯合成的。所获得的芳芳基芳烃显示出聚集诱导发射(AIE),其中在固态下观察到强发射(量子产率高达0.61),而相应的溶液的发射非常微弱。通过实验和计算方法检查了光学和电子性质。阐明了2,5位的芳基会影响前沿轨道和Arsole核的芳香性。另一方面,在1,3,5-位的那些垂直于发光体,对于限制聚集引起的猝灭有效。由于砷原子部分的芳香性低,因此砷原子的孤对具有足够的配位能力,合成了1,2,3,4,5-五苯基苯甲醚的氯化金(I)络合物。复合物的形成导致裸配体的发射发生蓝移。有趣的是,该配合物表现出发光的机械变色现象。研磨出蓝光的晶体(λ EM = 445纳米),得到无定形的样品用一蓝绿色的发射(λ EM = 496纳米)。
