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 (λem = 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 (λem = 440 nm) and also validated theoretically.
一种无金属的拓扑方法被证明可以通过合成两种 GFP 发色团集成的共轭微孔聚合物（o-HBDI-TEB-CMP 和 o-MBDI-TEB-CMP）来模拟天然 GFP 的光物理性质。有趣的是，由于结构刚性，羟基取代的 o-HBDI-TEB-CMP 的发射（λem = 515nm）和激发态寿命（4.1ns）被发现与天然 GFP 相似。-OH 基团对于绿色发射的关键作用进一步得到了 -OMe 取代的 o-MBDI-TEB-CMP（λem = 440nm）的支持，并从理论上得到了验证。
