R.sup.1 and R.sup.6 are each independently R or NHR, where R is aryl. R.sup.2 and R.sup.3 are each independently alkyl or aryl, or represent the carbon atoms necessary to form a fused ring with the phenyl ring to which the N atom is attached. R.sup.4 and R.sup.7 are each independently hydrogen, alkyl or aryl. R.sup.5 is alkyl. Z represents the atoms necessary to complete a 5 or 6 memebered heterocyclic nucleus. M.sup.+ is a cation. L.sup.1 through L.sup.7 are each independently methine groups. m is 0, 1, 2, or 3. n is 0 or 1. p is 0, 1, 2, 3, or 4. q is 0, 1, 2, or 3.
