## Abstract The effect of substituents on the position and intensity of the electronic absorption and fluorescence spectra of phthalocyanines (Pcs) was examined for 35 Pc compounds. When electronβreleasing groups are bound to four __Ξ±__βbenzo positions of the Pc skeleton, the B and Q bands shift to
Soluble and less soluble phthalocyaninatocopper(II) derivatives (4a and 4b) were prepared from the corresponding 7-[(4'-benzo-15-crown-5)oyl]-15, 16-dibromo-2,3,6,7,8,9,11,12-octahydro-5H-benzo[e]- ] tetraoxaazacyclopentadecine (3a) and 7-(2'-tosylaminoethyl)-15, 16-dibromo-2,3,6,7,8,9,11, 12-octahy
