Synthesis of Benzene-centered Trinuclear Phthalocyanines by Triple-click Chemistry
We disclose here the synthesis of novel benzene-centered trifluoroethoxy-coated trinuclear Pc 1 and its nonfluorinated analog 2 with flexible click spacers. UV-vis study reveals that trifluoroethoxy coating can result in the purely nonaggregated, windmill-like molecular structure of 1 without rigid spacers or any external source of help.
