Photocontrolled Isomerization Pathways of Tolylsulfonyl- and Pyrene-Linked Norbornadiene Systems Driven by Absorption Band Targeting
Norbornadiene (NBD) photoswitches are promising for molecular solar energy and information storage, as they isomerize to quadricyclane (QC) after absorbing irradiation energy. Here, we report pyrene-linked tolylsulfonyl-substituted NBD hybrids that enable wavelength-selective back-isomerization from QC to NBD. Using fe...
