Multistate Azobenzene-Norbornadiene Photoswitches for Molecular Solar Thermal Energy Storage.

ABSTRACT: The combination of two photochromic molecules into a multimodal photoswitch offers the potential to generate new properties related to molecular solar thermal (MOST) systems. A system can only be considered suitable for MOST applications if it meets key criteria, including a high quantum yield and an extended half-life of the high-energy isomer. Achieving this combination remains a significant challenge. In this study, we present the coupling of an azobenzene unit (AZO) with a norbornadiene system (NBD) via ester functions to develop new bi- and trimodal AZO-NBD photoswitches that exhibit synergistic effects. Photochemical studies reveal that both the NBD and AZO components of the hybrid are switchable. In one case, all isomer types could be selectively produced. Furthermore, each metastab
