To develop more H-shape nonlinear optical polymers, in this paper, four new polymers embedded with H-type chromophore moieties were designed and synthesized through a Suzuki coupling copolymerization reaction. The H-type chromophores were easily prepared by the utilization of Click Chemistry reactions, and their structures could be conveniently adjusted by changing the diazido groups. All the polymers exhibited good film-forming ability, thermal stability, and large optical nonlinearities. As a typical example, P4 demonstrated the highest d(33) value of 94.7 pm/V, and its onset temperature for decay was up to 103 degrees C, making it promising candidate for practical applications in photonic fields.
