Claim:
A compound having formula 1: [R k —Y—S(CH 2 ) n ] r -G-(CH 2 ) m —(SiX 1 X 2 X 3 ) (1) wherein each occurrence of Y is selected from the group consisting of —C(═NR 1 )—; —SC(═NR 1 )—; (—NR 1 )C(═NR 1 )—; —SC(═O)—; (—NR 1 )C(═O)—; (—NR 1 )C(═S)—; —OC(═O)—; —OC(═S)—; —C(═O)—; —SC(═S)—; —C(═S)—; —S(═O)—; (—NR)S(═O) 2 —; —SS(═O)—; —OS(═O)—; (—NR 1 )S(═O)—; —SS(═O) 2 —; (—S) 2 P(═O)—; —(—S)P(═O)—; —P(═O)(—) 2 ; (—S) 2 P(═S)—; —(—S)P(═S)—; —P(═S)(—) 2 ; (—NR 1 ) 2 P(═O)—; (—NR)(—S)P(═O)—; (—O)(—NR 1 )P(═O)—; (—O) 2 P(═O)—; —(—O)P(═O)—; —(NR 1 )P(═O)—; —(NR 1 ) 2 P(═S)—; (—NR 1 (—S)P(═S)—; (—O)(—NR 1 )P(═S)—; (—O)(—S)P(═S)—; (—O) 2 P(═S)—; —(—O)P(═S)—; and —(—NR 1 )P(═S), and wherein each occurrence of R is chosen independently from hydrogen, straight, cyclic, or branched alkyl, alkenyl groups, aryl groups, and aralkyl groups, with each R containing up to about 18 carbon atoms; each occurrence of G is chosen independently form a group consisting of a trivalent or polyvalent hydrocarbon group of 3 to 30 carbon atoms derived by substitution of alkane, alkene or aralkane or a trivalent or polyvalent heterocarbon group of 2 to 29 carbon atoms with the proviso that G contains a cyclic structure (ring); each occurrence of X 1 is independently selected from the set of hydrolysable groups—group consisting of —Cl, —Br, R 1 O—, R 1 C(═O)O—, R 1 2 C═NO—, R 1 2 NO— or R 2 N—, wherein each R 1 is chosen independently from hydrogen, alkyl, alkenyl, aryl or aralkyl groups with each R 1 containing up to about 18 carbon atoms; each occurrence of X 2 and X 3 are independently chosen from the group consisting of the members listed for R 1 and X 1 ; and, k is 1 to 2; m=1 to 5; n=1 to 5; r is 2 to 4.
