Abstract:
A composition having the structure ##STR108##whereina. A and B are the same or different, and each is a chemical bond; hydrogen; an electrophilic group; a nucleophilic group; R; an amino acid derivative; a nucleotide derivative; a carbohydrate derivative; an organic structural motif; a reporter element; an organic moiety containing a polymerizable group; or a macromolecular component, wherein A and B are optionally connected to each other or to other structures and R is as defined below;b. X and Y are the same or different and each represents a chemical bond or one or more atoms of carbon, nitrogen, sulfur, oxygen or combinations thereof;c. R and R' are the same or different and each is an alkyl, cycloalkyl, aryl, aralkyl or alkaryl group or a substituted or heterocyclic derivative thereof, wherein R and R' may be different in adjacent n units and have a selected stereochemical arrangement about the nitrogen atom to which they are attached;d. G is a chemical bond or a connecting group that includes a terminal carbon atom for attachment to the quaternary nitrogen and G may be different in adjacent n units; ande. n.gtoreq.1;provided that, (1) if G is a chemical bond, Y includes a terminal carbon atom for attachment to the quaternary nitrogen; and (2) if n is 1, X and Y are chemical bonds and R and R' are the same, A and B are different and one is other than H or R.
