Functional monomers and polymers. XXXXVII. Complex formation of stereoregular methacryloyl‐type polymers containing nucleic acid bases

Abstract

Abstract The complex formation between a poly( N ‐β‐methacryloyloxyethyl) derivative of adenine with one of thymine or uracil was studied in dimethyl sulfoxide and ethylene glycol mixture by ultraviolet (UV) spectroscopy. For the polymer pairs containing complementary nucleic acid bases both hypochromicity and hyperchromicity were found. Stereoregularity of the polymers, as well as the conditions for measurement of, for example, solvent, temperature, and time, affected the complex formation. Both inter‐ and intramolecular interaction of polymers in solution were discussed in some detail.
