Abstract:
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.
