Claim:
A dendritic polymer of generation n comprising: a central core § of valence m; generation chains branching around the core; an intermediate chain at the end of each generation chain that is present, or at the end of each bond around the core, where appropriate; and a terminal group at the end of each intermediate chain, wherein said terminal group is represented by the formula: -(A1)<[A2-P(═O)(OX) 2 ] 2 (T) wherein -A1< represents the radical —CR< or -Heteroatom<; the radicals A2, which are identical or different, each independently of the other represents a single bond or a linear or branched hydrocarbon chain having from 1 to 6 chain members, each of said chain members optionally being selected from a heteroatom, each chain member being optionally substituted by one or more substituents selected from -Alkyl, -Hal, —NO 2 , —NRR′, —CN, —CF 3 , —OH, - OAlkyl, -Aryl, and -Aralkyl; R and R′, which are identical or different, each independently of the other represents a hydrogen atom or an -Alkyl, -Aryl, or -Aralkyl radical; X represents an -Alkyl or -Aryl radical, —H or /M + , where M is a cation, m represents an integer greater than or equal to 1 n represents an integer from 0 to 12; and < represents two bonds situated on A1, wherein the intermediate chains are represented by formula: -J-K-L- (C2) wherein J represents an oxygen atom, a sulfur atom or a radical —NR—; K represents an -Aryl-, —C(═O), -Heteroaryl-, or -Alkyl- radical, each of which is optionally substituted by a Halogen atom or a —NO 2 , —NRR′, —CN, —CF 3 , —OH, -Alkyl, -Aryl, or -Aralkyl radical; L represents a linear or branched hydrocarbon chain having from 1 to 6 chain members and optionally having one or more double or triple bonds, each of said chain members optionally being a heteroatom, each chain member being optionally substituted by one or more substituents selected from -Alkyl, -Hal, —NO 2 , —NRR′, —CN, —CF 3 , —OH, —OAlkyl, -Aryl, and -Aralkyl, wherein R and R′, which are identical or different, each independently of the other represents a hydrogen atom or an -Alkyl, -Aryl, or -Aralkyl radical, wherein the generation chains are represented by the formula: -A′-(C═O)—N(R)—B′—N< (C1′) wherein A′ and B′ each independently of the other represents an -Alkyl, -Alkenyl, or -Alkynyl radical, each of which is optionally substituted by one or more substituents selected from -Alkyl, -Hal, —NO 2 , —NRR′, —CN, —CF 3 , —OH, —OAlkyl, -Aryl, and -Aralkyl; and R and R′, which are identical or different, each independently of the other represents a hydrogen atom or an -Alkyl, -Aryl, or -Aralkyl radical.
