Synthesis of octa-phenoxy substituted metallophthalocyanines and their green color filter application in liquid crystal display
Herein we report the synthesis of new octa-phenoxy substituted metallophthalocyanines (4-7) (M = Co, Ni, Cu and Zn). The synthesized compounds were characterized using FT-IR, UV-vis, elemental analyses and MALDI-TOF techniques. Further, the basic requirements such as aggregation behavior, thermal stability and solubility in propylene glycol monomethyl ether acetate (PGMEA) of compounds 4-7 were investigated for their usage as green color filter in LCD. Compounds 4-7 showed enough thermal stability and better solubility in PGMEA. Further, compounds 4-7 showed more than 90% of transmittance. Higher transmittance property along with thermal stability of compounds 4-7 promising as a green color filter in LCD.
