Electrochemical synthesis of phthalocyanine–molecular mixed crystals in dilute solution

Abstract We report the synthesis of a new phthalocyanine–molecular mixed crystal, TPP[Cr x Co 1− x (Pc)(CN) 2 ] 2 , by an electrochemical method using a dilute solution. For the whole range of x , the chemical composition of the obtained single crystals is homogeneous and nearly equal to the nominal one in the dilution solution, as revealed by energy-dispersive X-ray spectroscopy. We have found that the concentrations of the starting materials play a vital role in the homogeneous growth of mixed crystals.
