Abstract
Regioregular poly(3-hexylthiophene)s with chain lengths varying from 5 to 100 monomers are synthesized. Poly(3-hexylthiophene)s show in solution an unexpectedly significant second-order nonlinear optical response. The increase in transition dipole moment upon oligomerisation causes the significant second-order nonlinear optical response.
摘要
合成了链长从 5 到 100 个单体的规则交替聚（3-己基噻吩）。聚（3-己基噻吩）在溶液中表现出出乎意料的显著二阶非线性光学响应。低聚物化引起的跃迁偶极矩的增加导致了显著的二阶非线性光学响应。
