Ftalosiyanin esaslý boyarmaddelerin kimyasal yapýlarý ve fonksiyonel tekstillerin üretilmesinde kullanýmý

Ftalosiyaninler keskin mavi-yeþil renkli, oldukça saðlam, iki boyutlu 18 π-elektron konjuge sistemine sahip aromatik makrosiklik bileþiklerdir. Makrohalka yapýnýn merkezi koordinasyon boþluðuna periodik tablonun birçok elementinin; aromatik yapýnýn periferal ve non-periferal konumlarýna ise çeþitli fonksiyonel sübstitüentlerin baðlanmasýyla ftalosiyaninlere katalitik, elektrokromik, elektriksel iletkenlik, fotovoltaik, fotoiletkenlik, ýþýk absorbsiyonu, foto uyarýcý gibi çeþitli özellikler kazandýrmak mümkündür. Geleneksel bakýr ftalosiyanin pigmenti dýþýnda farklý ftalosiyanin türevlerinin de tekstil materyallerinin renklendirilmesinde kullanýlmasýyla; farklý fonksiyonel özellikli (güç tutuþur, antibakteriyel…vs) teknik tekstillerin elde edilebileceði düþünülmektedir. Bu sebeple bu araþtýrmada ftalosiyaninler hakkýnda genel bilgi verilip, tekstil materyallerinin renklendirilmesi ve antibakteriyel özellik kazandýrýlmasý üzerine yapýlmýþ bazý çalýþmalar anlatýlmýþtýr.

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

Phthalocyanines are intensely blue-green-coloured, quite stable aromatic macrocyclic compounds having a two-dimensional 18-π 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.
