Synthesis and Properties of Water-soluble Crosswise- disubstituted Phthalocyanines

Abstract
Crosswise-disubstituted metal-free phthalocyanines carrying two 2-(trimethylamino)ethylsulfanyl- and two amino groups on peripheral positions have been synthesized by 2:2 condensation of 5-[2-(dimethylamino)ethylsulfanyl]- 1,3-diiminoisoindoline and 1,1,3-trichloro-5-nitro-1H-isoindole.
