Changing the shape of chromophores from “H-type” to “star-type”: increasing the macroscopic NLO effects by a large degree
关键字：star-type, NLO polymer
In this paper, an NLO polymer P2, consisting of “star-type” chromophore, was first prepared through the Suzuki coupling reaction and the Sonogashira coupling reaction. For comparison, its “H-shape” analogue P1, only consisting of an “H-type” chromophore, was synthesized. To further enhance the NLO coefficient and stability, the “star-type” chromophore was also introduced into hyperbranched...
