Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2018 / V.30,no.3,Sept Title Synthesis of Blue-green Naphthoxy, Chloro Derivative Zinc-phthalocyanines with LCD Requirements Authors Rangaraju Satish Kumar, Kyeong Su Min and Young-A Son* Institution/Affiliations Chungnam National University Pages/Total page pp.159 ~ 167 / 9 Language English Abstract Here we designed and synthesized new zinc phthalocyanines and structures were fully confirmed by spectral and elemental analysis. All phthalocyanines have a very good solubility in industrial solvents like chloroform, dichloromethane, dimethyl sulfoxide, N,N-dimethyl formamide, propylene glycol monomethyl ether acetate (PGMEA), acetone, tetrahydrofuran and acetonitrile. UV-Visible absorption and transmittance in PGMEA showed that these dyes have suitable spectral properties for LCD color filters. By Triton X surfactant study, we confirmed that these dyes are not showing any aggregation in PGMEA. We dissolved the all phthalocyanines in LCD fabricating solvent (PGMEA), and all phthalocyanines showed more than 8 wt% of solubility. Finally, all of these results concluded that PCK1, PCK2 and PCK3 are fit for LCD green color filter.
