Abstract
AbstractPreparation 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.
