Synthesis of New Push-Pull Unsymmetrically Substituted Styryl Metallophthalocyanines: Targets for Nonlinear Optics

Abstract

Following our studies on styryl phthalocyanines with extended conjugation, we report here the synthesis and characterization of new push‐pull unsymmetrically substituted styryl phthalocyanines 2–6. They have been prepared for studying the influence of the position and electronic character of the substituents and the role of the central metal atom on their optical properties.

Microwave-assisted synthesis and characterization of phthalocyanines substituted with azo compound containing eugenol moiety

“…The most important industrial application of phthalocyanines is the formation of color complexes with metal cations that are used as highly stable pigments and dyes [2]. In addition, they can find commercial applications as: photovoltaic materials in solar cells [3e5], systems for fabrication of light emitting diodes (LED) [6,7], liquid crystalline [8], and non-linear optical materials [9,10], sensitizers for photodynamic (PDT) cancer therapy [11,12], photoconductors in xerography [13], dyes at recording layers for CD-R and DVD-R optical storage discs [14], as well as diverse catalytic systems [15,16]. Phthalocyanines are usually prepared by the high temperature cyclotetramerization processes of either phthalonitrile or phthalic anhydride, in which the template effect afforded by a suitable metal cation is required.…”
