提出了一种有效的方法，在氯化铝存在下，用芳基锡烷作为弱亲核试剂在硼上官能化BODIPY，提供新的芳基硼取代的BODIPY和氮杂BODIPY衍生物。大多数芳基硼取代的BODIPY在水溶液中表现出明亮的发光，并具有显著的聚集诱导发光增强和高的固态发光，这是由于中位苯基和硼取代芳基的旋转受限以及J型聚集体的形成。
An efficient procedure is presented for functionalization of BODIPYs at boron with arylstannanes as weak nucleophiles in the presence of aluminum chloride, providing new aryl-boron-substituted BODIPY and aza-BODIPY derivatives of singular importance. Most of these aryl-boron-substituted BODIPYs showed bright emission in the aqueous solution with significant aggregation-induced emission enhancement and high solid-state emission as a result of the restricted rotation of themeso-phenyl group and boron-substituted aryl groups as well as the formation ofJ-type aggregates.
