ABSTRACT:
Compounds having properties superior to known photosensitizers defined by the following chemical formula: ##STR1## including R groups R.sup.1, R.sup.2, R.sup.3, and R.sup.4, wherein R.sup.1 and R.sup.2 are methyl or --CH(O--(CH.sub.2).sub.n CH.sub.3)CH.sub.3 or are joined together to form the group D and wherein R.sup.3 and R.sup.4 are methyl or --CH(O--(CH.sub.2).sub.n CH.sub.3)CH.sub.3 or are joined together to form the group D; provided that one of R.sup.1 and R.sup.2 or R.sup.3 and R.sup.4 are joined together to form the group D wherein one of the remaining R groups is methyl and one of the remaining R groups is --CH(O--(CH.sub.2).sub.n CH.sub.3)CH.sub.3, where n is an integer of 5 through 7 and group D is: ##STR2## and R.sub.5 is independently at each occurrence --OR.sub.6 where R.sub.6 is lower alkyl of 1 through 7 carbon atoms or R.sub.6 is an amino acid residue.
