Optical limiting properties of low-symmetry magnesium phthalocyanine complex bearing a pentachlorocyclotriphosphazene moiety

Phthalocyanines (Pc) are represented as the conjugated electronic system that can be readily affected by simple chemical reactions to create effective optical limiters. This work demonstrates the result of the interaction of nanosecond laser radiation (16 ns) at the second harmonic wavelength of 532 nm with the solution of asymmetrically substituted magnesium phthalocyanine complex (ppz- Pc ^t Mg), containing one pentachlorocyclotriphosphazene fragment at the periphery, in the tetrahydrofuran (THF).
