通过2-甲酰基吡咯与α，β-环己二烯稠合联吡咯的一锅缩合反应，合成了一系列高度稳定的构象受限的部分稠合和完全稠合BODIPY二聚体（α，β-环己二烯稠合和α，β-苯稠合二聚体）3.通过X射线分析、密度泛函理论（DFT）计算以及电化学和光学测量观察到这些稠合BODIPY二聚体上的π-共轭的有效扩展，如通过它们在近红外（NIR）范围（650至820 nm）内的强吸收和发射所证明的。
A set of highly stable conformation-restricted partially and fully fused BODIPY dimers (α,β-cyclohexadiene-fused and α,β-benzene-fused dimers) were synthesized from a one-pot condensation of 2-formylpyrroles with α,β-cyclohexadiene-fused bipyrrole3. Effective expansion of π-conjugation over these fused BODIPY dimers was observed by X-ray analysis, density functional theory (DFT) calculations, and electrochemical and optical measurements, as demonstrated by their strong absorption and emissions in the near-infrared (NIR) range (650 to 820 nm).
