A metal free topological approach is demonstrated to mimic the photophysical properties of natural gfp by synthesizing two gfp chromophore integrated conjugated microporous polymers (o-HBDI-TEB-CMP and o-MBDI-TEB-CMP). Interestingly, owing to the structural rigidity, the emission (λ_em = 515 nm) and excited state lifetime (4.1 ns) of hydroxy substituted o-HBDI-TEB-CMP are found to be similar to the natural gfp. The crucial role of the –OH group for the green emission is further supported by –OMe substituted o-MBDI-TEB-CMP (λ_em = 440 nm) and also validated theoretically.

Gfp发色团集成的共轭微孔聚合物：拓扑和ESPT对发射特性的影响†

通过合成两种gfp发色团集成的共轭微孔聚合物（o -HBDI-TEB-CMP和o -MBDI-TEB-CMP），证明了一种无金属的拓扑方法可模仿天然gfp的光物理性质。有趣的是，由于结构刚性，发射（λ _EM = 515纳米）和羟基取代的激发态寿命（4.1纳秒）Ô -HBDI-TEB-CMP被发现是类似于天然GFP。用于绿色发射的-OH基团的关键作用是通过进一步支持-OMe取代ö -MBDI-TEB-CMP（λ _EM = 440纳米），并且还从理论上验证。
