Abstract

Aryl‐maleimides undergo a novel [2+4]‐photodimerization instead of the expected [2+2]‐photodimerization under both direct irradiation with visible light and under sensitized energy transfer conditions. This new excited state reactivity in aryl‐maleimides is deciphered through photochemical, photophysical, and spectroscopic studies. The stereochemistry of the photodimer depends on the type of non‐bonding interactions prevalent during photodimerization which is in turn dictated by the substituents on the maleimide ring. More importantly, the stereochemistry of the photodimer formed is complementary to the product observed under thermal conditions. [ABSTRACT FROM AUTHOR]

Abstract

Renewable polymeric materials derived from biomass with built-in phototriggers were synthesized and evaluated for degradation under irradiation of UV light. Complete decomposition of the polymeric materials was observed with recovery of the monomer that was used to resynthesize the polymers. [ABSTRACT FROM AUTHOR]

Abstract

Renewable polymeric materials derived from biomass with built‐in phototriggers were synthesized and evaluated for degradation under irradiation of UV light. Complete decomposition of the polymeric materials was observed with recovery of the monomer that was used to resynthesize the polymers. Biodegradable and recyclable: Renewable polymeric materials derived from biomass with built‐in phototriggers were synthesized and evaluated for degradation under irradiation by UV light (see picture). Complete decomposition of the polymeric materials was observed with recovery of the monomer that was used to resynthesize the polymers. [ABSTRACT FROM AUTHOR]
