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 techni
ques, such as transient absorption, Z-scan, and degenerate four-wave mixing
(DFWM), were used for assessing the optical properties and optical limitin
g performance of the indium phthalo- and naphthalocyanines. (C) 2001 Elsevi
