Abstract:

A straightforward, efficient, and generalizable synthesis of symmetrically substituted 2,3,9,10,16,17,23,24-octaalkyl phthalocyanines and 2,3,9,10,16,17,23,24,30,31-decaalkyl uranyl superphthalocyanines from o-dialkyl benzenes is described. For phthalocyanines, the approach is illustrated for methyl and n-butyl substituents. and both metal-free and nickel complexes are reported. Uranyl superphthalocyanines have been prepared with methyl and n-butyl substituents. The new complexes have been characterized by a variety of chemical and physicochemical methods. Quantitative determination of the solubilities of substituted and unsubstituted phthalocyanine and superphthalocyanine complexes in both 1,2,4-trichlorobenzene and toluene demonstrates decreasing solubility in the order 4,5-Bu25SPcUO2 4-Me5SPcUO2 4,5-Me25SPcUO2 - SPcUO2 4-Me4PcH2 Ni4,5-Bu2Pc Ni4,5-Me2 4Pc - NiPc. Attempts to displace the uranyl ion from 4,5-R25SPcUO2 with acids or CuOAc2 lead to the formation of 4,5-R24PcH2 or Cu4,5-R24Pc, respectively. Author
