摘要: Abstract The octasubstituted (phthalocyaninato)titanium complexes [Pc′(R)8]TiO (Pc′=2,3,9,10,16,17,23,24-octasubstituted phthalocyaninate; R=n-C7H15 (1), OC5H11 (2)) have been prepared by treating the corresponding substituted dicyanobenzenes C6H2(CN)2(R)2 with TiCl4 or Ti(OC2H5)4 in presence of urea. Compound 1 reacts catechol to give catecholato complex [Pc′(C7H15)8]Ti(O2C6H4) (3). electronic absorption spectra measured a wide range non-coordinating and coordinating solvents. solvent effects are mainly due solvation band positions depend on polarity power Aggregation has also shown exist for compound hexane, but not chloroform.
