Abstract

Four Cr and Co based metal complex derivatives for new violet and red color filters were first synthesized by using naphthol and pyrazole groups as well as azo moiety. The UV-visible maximum values of Co (HPANT) 2 and Cr (HPANT) 2, the naphthol derivatives, were 560 and 561 nm respectively in solution state where both were violet colored solids. Co (HPAPMP) 2 and Cr (HPAPMP) 2, the pyrazole derivatives also showed UV-visible ...
