Indium phthalocyanines and naphthalocyanines for optical limiting

摘要

In this work, an overview of optical limiting processes in phthalocyanines is given. The synthesis and the linear and nonlinear optical properties of a series of highly soluble axially substituted indium (Ⅲ) phthalocyanines and the analogous series of naphthalocyanines are described. Several techniques, such as transient absorption, Z-scan, and degenerate four- wave mixing (DFWM), were used for assessing the optical properties and optical limiting performance of the indium phthalo-and naphthalocyanines.
