Two novel narrow-bandgap A-π-D-π-A-type BODIPY dyes were synthesized via a one-step Stille reaction with “D-π” segment at the β-site of BODIPY unit, where CTBDP-based device gave an impressive PCE of 5.85% with an excellent Jsc of 17.70 mA cm−2.
通过一步Stille反应合成了两种新型窄带隙A-π-D-π-A型BODIPY染料,其中“D-π”段位于BODIPY单元的β位,CTBDP基础器件具有令人印象深刻的5.85%的PCE和出色的17.70 mA cm-2的Jsc。
