π-Conjugated aza-BODIPYs with absorption in the near-infrared region have attracted attention, but there are few reports of their synthesis. We report the synthesis and absorption properties of π-conjugated asymmetric aza-BODIPYs by nitrosation and retro-Diels-Alder reaction of bicyclo[2.2.2]octadiene-fused bicyclopyrroles. We also synthesized aza-BODIPY fused with [2.3]naphtho and [2.3]anthra structures
在近红外区域具有吸收的π-共轭氮杂-BODIPYs引起了人们的关注,但对其合成的报道很少。我们报告了通过双环[2.2.2]辛二烯稠合双环吡咯的亚硝化和逆-Diels-Alder 反应合成π-共轭不对称氮杂-BODIPYs 的性质和吸收性能。我们还首次通过该方法合成了融合[2.3]萘和[2.3]蒽结构的aza-BODIPY和π-共轭氮杂-O-螯合物BODIPY。
