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 one polymerizable group , macromolecular component , resin , silicate , other surface and particle support , the diversity elements can be the same , can be different , and can also be connected to form a ringed to several ringed species .
