We show that polyoxometalates (POMs) are an excellent redox-active acceptor on which to base high performance 2(nd) order non-linear optical (NLO) chromophores. This is demonstrated through three new organoimido-Lindqvist derivatives with HRS β0-values exceeding those of any dipolar organic system with comparable donor, π-system and absorption profile. Thus, organoimido POMs may provide a new generation of high performance, high transparency, and potentially redox-switchable NLO materials.
我们表明，多金属氧酸盐（POMs）是一种出色的氧化还原活性受体，可作为高性能二阶非线性光学（NLO）发色团的基础。通过三种新的有机亚胺基-林德奎斯特衍生物得以证明，其HRSβ0值超过了任何具有可比供体、π体系和吸收谱的偶极有机体系。因此，有机亚胺基POMs可能会提供新一代高性能、高透明度且潜在可氧化还原切换的NLO材料。
