Abstract: This invention relates to a class of aminimides structurally characterized as an acyl nitrogen-nitrogen ylide such that the acyl moiety possess the structural diversity element G, the quaternary nitrogen possess structural diversity elements E and F, and the quaternary nitrogen is bonded to a hydroxyethyl substituent, which in turn is bonded to an aminomethylene moiety that possess structural diversity elements A and B from the amino group and diversity element C from the methylene substituent, as shown below, ##STR1## wherein structural diversity element A, B, C, D, E, F and G are chosen from the set of elements consisting of substituted and unsubstituted as well as branched and straight chain alkyl, aryl, alkaryl, aralkyl, carbocyclic, heterocyclic, hydrogen, amino acid, peptide, polypeptide, protein, depsipeptide, carbohydrate derivatives, nucleotide derivatives, oligonucleotide derivatives, naturally occurring or synthetic organic structural motifs, reporter elements, organic moieties containing at least
