The Synthesis of Picolinamide-Supported Tetracoordinated Organoboron Complexes with Aggregation-Induced Emission Property

Abstract

The picolinamide-supported tetracoordinated organoboron complexes containing diaryl boronyl segments have been synthesized for the first time. Aryl trifluoroborates were utilized as the BAr2 sources to introduce different aryl motifs with diverse functional groups. The optical experiments discovered these five-membered boron-containing complexes were aggregation-induced emission (AIE) active, thus affording a new class of AIE molecules.

Synthesis of Isoquinoline-3-carboxylate Chelated B,B-Diaryl Tetracoordinated Organoboron Complexes

“…其中, 宋秋玲课题 组 [12] 将 ArBF 3 K 应用到合成 N,C-螯合的 B,B-二芳基型络 合物中, 郝二宏课题组 [13] 与 Kanai 课题组 [14] 则分别独立 开发了制备 N,N-螯合的 B-芳基型 BODIPY 络合物的方 法. 前期研究中, 我们课题组也利用 ArBF 3 K 实现了 N,N-螯合的 B,B-二芳基型络合物的制备, 螯合配体可以 来自 8-氨基喹啉 [15][16] 或者吡啶-2-甲酰胺骨架 [17] [15,[18][19] . 因此, 使用化合物 3a 对所得 N,O-螯合型化合 物进行了光催化性能测试.…”
