Dendronized hyperbranched polymers (DHPs) are a promising structure platform for high-performance second-order nonlinear optical (NLO) materials. A new A(3)+B-2-type DHP (HP2) was reported, which exhibited high thermal stability and a high second-harmonic generation coefficient, making it suitable for second-order NLO applications.
Dendronized hyperbranched polymers (DHPs) can provide advantages for both hyperbranched polymers and dendrimers, making them a promising structure platform for high-performance second-order nonlinear optical (NLO) materials. Herein, a new A(3)+B-2-type DHP (HP2) is reported through facile and efficient [2+2] cycloaddition polymer postfunctionalization, in which tetracyanobutadienyl-based moieties are introduced as the main chromophores while isophorone-bridged moieties serve as the isolation chromophores. Benefiting from this unique hyperbranched structure design, the measured second-harmonic generation coefficient of HP2 can reach up to 96.6 pm V-1 with high thermal stability, making it a good material candidate for second-order NLO applications.
