We have developed a high-yielding new route to substituted cycloparaphenylenes via the cationic rhodium(I)-catalyzed intermolecular [2+2+2] cycloaddition of cyclophenylene-ethynylenes with monoynes. The thus obtained products, substituted [8]cycloparaphenylene-triphenylenes, exhibited definite aggregation-induced emission (AIE), and are noteworthy as a novel AIE-active cycloarylene that does not have
我们开发了一种通过阳离子铑 (I) 催化的亚环苯基-亚乙炔与单炔烃的分子间 [2+2+2] 环加成来获得取代环对亚苯基的高产新途径。由此获得的产物,取代的[8]环对苯并苯并苯,表现出明确的聚集诱导发光(AIE),并且作为一种新型AIE活性亚环芳基值得注意,它不具有通常的AIE发光体,如四苯-乙烯和苯骨架。
