m is an integer ranging from 0 to 4; A1 represents a function —COOR1 in which R1 is a hydrogen atom or an alkali metal cation; or a group A2; A2 represents a group —P(O)(OCH2CH3)(OR2) or —P(O)(OR2)2 in which R2 represents a hydrogen atom or an alkali metal cation; W1 represents a hydrogen atom, a heteroatom, a halogen atom, a non-coordinating solubilizing function, a polyethylene glycol chain, or a function that is capable of changing the electron delocalization of the photon-collecting antenna; each of the groups Y1 and Y2 represents an H atom, an amino or thiol group, or alternatively Y1 and Y2 together form a diradical forming one or more aromatic or heteroaromatic rings with the two carbon atoms that bear them; B represents a bonding segment consisting of at least one group chosen from —CO—NH—, peptide groups containing from 1 to 4 amino acids, alkylene groups containing from 2 to 10 carbon atoms and optionally comprising at least one heteroatom in the carbon chain, and alkynyl groups containing from 2 to 10 carbon atoms and optionally comprising at least one heteroatom in the carbon chain; D represents an oxygen or sulfur atom, a linear alkyl chain, a cycloalkane or an aryl; Z is:
NH2, a halogen, a phosphate,a group COOR3 in which R3 is H, an alkali metal cation, a quaternary ammonium group N(R4)4+ in which R4 is H or a linear alkyl chain, a succinimide group —N—(CO—CH2—CH2—CO)— or a pentafluorophenyl group —C6F5;a biotin function (—CO—(CH2)4—C5H7N2OS), a polyheteroaromatic group or a crown ether,a silyl organic cluster or a mineral cluster;a macroscopic support. |
