Chemical structures of phthalocyanine based dyestuffs and their useage in production of functional textiles

Abstract

Phthalocyanines are intensely blue-green-coloured, quite stable aromatic macrocyclic compounds having a two-dimensional 18-pi electron conjugated system. Phthalocyanines are acquired various properties such as catalytic, electrochromic, electrical conductivity, photovoltaic, photo-conductivity, photo-absorbtion, photosensitizer by bonding most elements of the periodic table to central coordination cavity of macrocylic structure and by linking various functional substituents to peripheral or non-peripheral position of aromatic structure. It is thought that technical textiles having different functional properties, e.g.; antibacterial, fire retardant, can be obtained by also using various phthalocyanine derivatives except traditional copper phthalocyanine pigment in colouration of textile materials. For this reason, in this research general knowledge about phthalocyanines were given then some studies about their usage in textile material colouration and being achieved antibacterial properties were told.
