In this study, two new dendronized nonlinear optical (NLO) polymers were synthesized with high FTC chromophore loading density by introduction of high generation chromophore dendrons on the side chains. Due to their suitable molecular weights, both of them possessed good solubility in common solvents. They also inherited the advantages of dendrimers (large NLO coefficient), especially for PG2 whose NLO coefficient d33 value was as high as 282 pm·V-1. Also, PG2 had a good temporal stability with 80% of its maximum value being retained at the temperature as high as 129 °C.

具有高FTC发色团负载密度的树枝状聚合物:大的二阶非线性光学效应,良好的时间和热稳定性

在这项研究中,通过在侧链上引入高代发色团树突,合成了两种具有高FTC发色团负载密度的新型树枝化非线性光学(NLO)聚合物。由于它们合适的分子量,它们在普通溶剂中都具有良好的溶解性。他们还继承了树枝状聚合物(NLO系数大)的优点,尤其是对于NLO系数d 33值高达282 pm·V -1的PG2。同样,PG2具有良好的时间稳定性,其最大值的80%保留在高达129°C的温度下。
