Abstract

A series of organic salts, in which the cation has been designed to have a large molecular hyperpolarizability, has been prepared. Variation of the counterion (anion) in many cases leads to materials with large powder second harmonic generation efficiencies, the highest of which is roughly 1000 times that of a urea reference.

摘要

已经制备了一系列有机盐，其中阳离子被设计为具有较大的分子超极化率。在许多情况下，改变抗衡离子（阴离子）可以得到具有较大粉末二次谐波产生效率的材料，其中最高的大约是尿素参考物的 1000 倍。
