Patent ID: 7666898

Claim:
A composition of matter comprising a substituted organic compound, or a salt thereof, wherein the substituted organic compound has two or more independently selected multi-ring structures, Z, linked by independently selected linking moieties, L, to a multifunctional bridge moiety, as represented by formula (D-I) with n being an integer ranging from 0 to 2, the two or more multi-ring structures, Z, being covalently bonded to the multifunctional bridge moiety through corresponding linking moieties, L, each of the two or more multi-ring structures is a fused five-membered ring and six-membered ring represented by formulas (I) or (II) R 1 through R 7 each being independently selected from the group consisting of hydrogen, halide, oxygen, sulfur, phosphorus, hydroxyl, amine, thiol, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, ether, carbonyl, acidic, carboxyl, ester, amide, carbocyclic, acylamino, oximyl, hydrazyl and combinations thereof, provided that R 1 is C 4 -C 36 alkyl or substituted C 4 -C 36 alkyl; wherein R 1 is linked to a linking moiety L; R 2 is alkyl or substituted alkyl; L is selected from O and S; and the multifunctional bridge moiety having at least (n+2) reactive sites to which the corresponding linking groups of the two or more multi-ring structures are bonded, the multifunctional bridge moiety being selected from the group consisting of alkyl, phenyl, and combinations thereof.
