Abstract:
A compound having the formula ##STR20##whereineach of R.sup.1, R.sup.2, and R.sup.3 is independently a linear hydrocarbon that is saturated or unsaturated, has 1-22 carbons, optionally incorporates a 5- or 6-membered unsaturated hydrocarbon ring, and is optionally substituted by one or more halogens; provided that at least one of R.sup.1, R.sup.2, and R.sup.3 is substituted by ##STR21##whereinZ is selected from the group consisting of Cl, Br and I;R.sup.a and R.sup.b are selected from the group consisting of H and CH.sub.3 ;X is halogen; andR.sup.c is selected from the group consisting of alkyl having 1-6 carbons; perfluoroalkyl having 1-6 carbons; and phenyl that is optionally substituted one or more times by alkyl having 1-6 carbons, perfluoroalkyl having 1-6 carbons, H, Cl, Br, I, NO.sub.2 or CN;R.sup.4, R.sup.5, R.sup.6, and R.sup.7 are independently H, halogen, CN, phenyl, --OR.sup.12 or --SR.sup.12 ; an alkyl group having 1-22 carbons that is optionally and independently substituted by one or more halogens; or any two adjacent substituents of R.sup.4, R.sup.5, R.sup.6, and R.sup.7 in combination form a single fused benzo substituent; where R.sup.12 is an alkyl group having 1-6 carbons, or 1-2 alicyclic, heteroalicyclic, aromatic or heteroaromatic rings, containing 1-2 heteroatoms, wherein the heteroatoms are N, O, or S;R.sup.8, R.sup.9, R.sup.10 and R.sup.11 are independently H, halogen, CN, phenyl, --OR.sup.15 or --SR.sup.15 ; an alkyl group having 1-22 carbons that is optionally and independently substituted by one or more halogens; or any two adjacent substituents of R.sup.8, R.sup.9, R.sup.10 and R.sup.11 in combination form a single fused benzo substituent; where R.sup.15 is an alkyl group having 1-6 carbons, or 1-2 alicyclic, heteroalicyclic, aromatic or heteroaromatic rings, containing 1-2 heteroatoms, wherein the heteroatoms are N, O, or S;W is selected from O, S, Se, Te or CR.sup.13 R.sup.14 where R.sup.13 and R.sup.14, which may be the same or different, are independently alkyl groups having 1-6 carbons, or R.sup.13 and R.sup.14 taken in combination complete a five or six membered saturated ring;n=0-3; and.PSI..sup.- is a biologically compatible counterion.
