Preparation and optical properties of linear polyethylenimine (PEI) containing L-(-)-N-[(-)-2-(thymin-1-yl) propionyl] prolyl group as grafting pendant, [P-(-)Pro-(-)T], and its related monomer and dimer model compounds are described. Hypochromic effects and circular dichroism of these compounds were compared with those of PEI containing (-)-2-(thymin-1-yl) propionyl group as grafting pendant, [P-(-)T], which has no L-proline ring as a spacing group. P-(-)Pro-(-)T showed no exciton coupling of B2u π-π* transition although it showed large hypochromicity in neutral aqueous solution, implying that the stacking of the bases has no screw sense.
