Development of a solar energy storage process. Photoisomerization of a norbornadiene derivative to a quadricyclane derivative in an aqueous alkaline solution
In an alkaline aqueous solution, photochemical valenceisomerization of norbornadiene derivative 1 to quadricyclane derivative 2 occurred quantitatively, and reverse isomerization of 2 to 1 under release of heat was achieved by catalytic action of cobalt hematoporphyrin 3 and analogues. This system may be of a great practical use for a solar energy storage.
