Low Molecular Weight Norbornadiene Derivatives for Molecular Solar
A series of substituted donor–acceptor norbornadienes with cyano acceptors and ethynyl‐aryl donor units has been synthesized and evaluated in the context of molecular solar‐thermal energy storage. A key step in the synthesis is a procedure for the formation of 2‐cyano‐3‐chloronorbornadiene from readily available starting materials.
Two-way photoswitching norbornadiene derivatives for solar energy storage
Molecular photoswitches of norbornadiene (NBD) derivatives have been effectively applied in molecular solar-thermal energy storage (MOST) by photoisomerization of NBD to a quadricyclane (QC) state.

The Norbornadiene/Quadricyclane Pair as Molecular Solar
So-called molecular solar thermal (MOST) systems[6] combine the light-harvesting process with storage of the gained energy in a single step. Upon irradiation, an energy-lean parent compound is converted into its energy-rich valence isomer. In the latter, the energy difference between the two photoisomers
