Development of One-Photon NIR Photoswitches
Incorporation of molecular switches in complex molecular systems allows dynamic alteration of their intrinsic properties and function with light in a remote and non-invasive fashion. For most of these applications, visible or near-infrared (NIR) light is more suitable than UV light due to its enhanced penetration depth and reduced radiation damage. However, the isomerization of photoswitches usually requires high-energy photons in at least one direction, which limits their utilization especially in biological applications. We develop tunable direct one-photon NIR photoswitches based on negative photochromic dihydropyrenes carrying opposing strong donor-acceptor substituents either along the long axis of the molecule or across it. This allows large temporary changes of their properties upon visible or NIR light-induced photoisomerization.
