Claim 0:
1. A composition comprising a tetraaryl ammonium salt represented by Formula 5:, wherein:
each B represents independently a bond, or is absent;
A− is a counter anion; and
each X1 independently comprises an all-carbon aryl ring, a substituted all-carbon aryl ring, a heteroaryl ring, or a substituted heteroaryl ring, wherein each of said substituted aryl ring and said substituted heteroaryl ring comprises one or more substituents selected from the group consisting of: a hydroxy group, an alkoxy group, an amino group, an aminoalkyl group, a guanidine group, a thioalkoxy group, a mercapto group, a cyano group, a haloalkyl group, an arylalkyl group, a nitro group, an azo group, a heteroalkyl, a sulfonate group, a sulfinyl group, a vinyl group, an allyl group, an alkyne, a thioalkyl group, an alkylhydroxy group, a keto group, a carboxylic acid derivative, and a sulfone group or any combination thereof;
and wherein:
at least one B is a bond;
with the proviso that at least one of said X1 is selected from the group consisting of a substituted all-carbon aryl ring, an unsubstituted heteroaryl ring, and a substituted heteroaryl ring, wherein said substituted all-carbon aryl ring comprises one or more substituents selected from a hydroxy group, an alkoxy group, an amino group, an aminoalkyl group, an alkyhydroxy group, and any combination thereof.
