摘要

Abstract

The development of organic second-order nonlinear optical (NLO) materials critically depends on achieving a non-centrosymmetric arrangement of chromophores to maximize macroscopic NLO coefficients. Recently

dendronized hyperbranched polymers (DHPs) have emerged as promising candidates due to their unique spatial architectures

which suppress unfavorable aggregation and stabilize ordered orientation. The central cores serve as a key factor governing the branching topology of the resulting polymers. Herein

a series of DHPs were constructed by regulating the configuration of branching cores containin

g ether bonds with low rotational barriers. Driven by the synergy between an optimized static topological architecture and the dynamic modulation of low-rotational-barrier linkers

DHP-PhO achieved an optimal combination of a high NLO coefficient (

=263 pm·V

−1

) and robust thermal stability (

80%

=120 °C). This work provides a viable molecular design strategy for developing high-performance organic NLO polymers through the integration of topological engineering and core structure modulation

which is expected to promote the practical application of organic NLO materials in advanced optoelectronic devices.
