| 摘要 |
The invention relates to fluorescent polymers soluble in an aqueous solution carrying at least 5 fluorophores which are distributed on the polymer and which exhibit the following properties: the fluorophores are water-soluble, the fluorophores are not self-associated in water at a concentration of less than or equal to 10-4 mol/l, preferably at a concentration of less than or equal to 10-3 mol/l, the fluorophores which are free in the aqueous solution have a molar extinction coefficient of greater than 1000 M-1.cm-1, preferably greater than 5000 M-1.cm-1, the fluorophores which are free in the aqueous solution have a quantum yield of greater than 0.3, preferably greater than 0.6, said polymers having a fluorescence amplification factor of greater than or equal to 0.35 per kg/mol of polymer, preferably greater than 0.45 per kg/mol of polymer.
