摘要

由透明聚合物基体和光学非线性活性分子组成的主客体体系是光学非线性器件的关键材料之一。在实际应用中,材料应具有较大的非线性和较长的寿命。这种由聚丙烯酰胺衍生物和对硝基苯胺制成的主-客系统已由本作者小组开发出来。根据180天的非线性磁化率变化估计,在室温下的寿命有望超过10年。对于长寿命材料,这种传统的评估可能不够准确,因为寿命比普通可用的实验周期长10~1000倍。本文以高温下的寿命数据为基础,用阿伦尼乌斯图估计了室温下的寿命。这种方法似乎比传统的方法更准确,更省时。

Evaluation of Nonlinear Optical Host-Guest Systems with Long Lifetime
Host-guest systems which consist of transparent polymer matrices and optical nonlinear active molecules, are one of the key materials for optical nonlinear devices. For practical use, the materials should have both large nonlinearity and long lifetime. Such host-guest systems, made of poly-acrylamide derivatives and p-nitroaniline, have been developed in the group of present authors1). The lifetimes at room temperature are expected to be more than several 10 years, as were estimated from the changes in nonlinear susceptibility over 180 days. Such a conventional evaluation might not be sufficiently accurate for long lifetime materials, because the lifetime is 10~1000 times longer than the ordinary available experimental period. In this paper we estimated the lifetime at room temperature from the Arrhenius plot based on the lifetime data at elevated temperature. This method seems to be more accurate and timesaving than the conventional one.
