We have synthesized a vinyl monomer having a psoralen moiety, which can form a photoadduct with double-helical DNA. The monomer 1 was proved to have an ability to crosslink DNA double strands through a photochemical reaction when irradiated by UV light. The resulting DNA having vinyl groups was copolymerized with a comonomer such as acrylamide and N-isopropylacrylamide to give rise to a DNA—vinyl polymer conjugate. A conjugation based on covalent bondings was verified by using gel electrophoresis; the conjugation efficiency was found to be dependent upon concentration of the monomer which had been used in the antecedent photochemical reaction. This monomer will be a useful tool when anchoring double-helical DNA on polymeric materials for separating and sensing DNA-binding substances.
