Synthesis and characterization of naphthalocyanines and phthalocyanines of use in sensitizer studies

Abstract
Methods for the preparation of the naphthalocyanines SiNc(OSi(n-C6H13)3)2, SiNc(OSi(i-C4H9)2n-C18H37)2, GeNc(OSi(n-C6H13)3)2, SnNc(OSi(n-C6H13)3)2, AlNcOSi(n-C6H13)3 ' and GaNcOSi(n-C6H13)3 the halonaphthalocyanine isomer mixtures SiMc(Cl)4(OSi(n-C6H13)3)2 and SiNc(Br)4(OSi(n-C6H13)3)2; and the butoxyphthalocyanines GePc(0-n-C4H9)g(OSi(C2H5)3)2 , SnPc(O-n-C4H9)8(OSi(C2H5)3)2, Al(O-n- C4H9)8OSi(C2H5)3 , Ga(O-n-C4H9)8OSi(C2H5)3 , PdPc(O-n-C4H9)8, and Ru(O-n- C4H9)8(C6H5N)2 are outlined. Ultraviolet-visible spectra and other properties of these compounds are described, and their potential as sensitizers is touched upon.
