Abstract

Herein, 1‐azaazulene‐based BF₂ complexes with pyrrole as the amido N‐donor were synthesized via Suzuki‐Miyaura cross coupling of 2‐bromo‐1‐azaazulene and 1‐Boc‐2‐pyrroleboronic acid. The structures, especially the unique N−B linkages, were discussed based on the single crystal analysis and DFT calculations. Compared to the parent BODIPY, the unsubstituted complex 3 a exhibited similar absorption maximum and three times larger Stokes shift. The optical properties can be further tuned by introducing aryl substituents at the α‐position of pyrrole moiety.

2‐（1‐氮杂烯基）吡咯‐二氟化硼配合物的设计、合成和光学性质

本文通过2 -溴- 1 -氮唑烯与1 - Boc - 2 -吡咯硼酸的Suzuki - Miyaura交叉偶联，合成了以吡咯为氨基给体的1 -氮唑烯基BF2配合物。基于单晶分析和DFT计算，讨论了其结构，特别是独特的N - B键。与母体BODIPY相比，未取代的配合物3a具有相似的吸收最大值和3倍大的Stokes位移。通过在吡咯部分的α‐位置引入芳基取代基，可以进一步调整其光学性质。

期刊介绍： Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC) The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
