Organic photochemistry with 6.7 eV photons: Tetracyclo[3.2.0.0^2,70^4,6]heptane (quadricyclene)

Abstract

Irradiation of quadricyclene in solution leads to isomeric products in addition to bicyclo [2.2.1]hepta-2,5-diene, which reduces its usefulness in solar energy storage. © The Royal Society of Chemistry, 1982.
