The present invention is phthalocyanine compounds with peripheral siloxane substitution,
as well as methods for making these compounds and various uses thereof, having
the basic structure:
##STR1##
wherein
- -W-X-Y-Z are peripheral groups comprising individual W, X, Y, and Z subgroups;
- W is a linkage represented by the formula: -D-(R1)0,1-,
where D=S or O;
- X is: -(CH2)n-, n=2 to 8;
- Y is a siloxane chain;
- Z is an aryl or alkyl terminal cap;
- M is two protons or a metal ion;
and forms a transparent film of high optical quality with large nonlinear absorption
and thermal refraction, free of scattering from solid or liquid crystalline domains
making them highly suitable for use as the active component in thin films, protective
eye wear, and optical data storage applications.
