Organic Spin-State Photoswitches.

ABSTRACT: Organic spin-state photoswitches represent an emerging class of molecular systems capable of reversibly modulating electronic spin states using light. This review provides a comprehensive overview of the fundamental mechanisms underlying two principal switching modes: photoconformational and photochemical. Emphasis is placed on their structural design, magnetic behavior, and the methods used for their characterization, including electron paramagnetic resonance (EPR) and UV-vis spectroscopy. Selected examples illustrate the ability of these systems to control spin-polarized states, alter magnetic exchange interactions, or switch between singlet and triplet spin states upon photoirradiation. The review also discusses challenges related to thermal stability, bistability, and operation under a
