Solvent-coordination directed control of electron transfer dynamics in photoactive complexes

Photochromic materials attract significant attention for their applications in anticounterfeiting devices, optical switches and molecular sensors. However, the influence of solvent molecules, particularly coordinated solvents, on electron transfer (ET) photochromic systems remains poorly understood. In this study, we synthesized a series of isostructural metal-organic complexes (MOCs), [Mn(ADC)(L)]n (ADC = 9,10-anthracenedicarboxylic acid, L = DMF for 1, DMA for 2, MEA for 3, and DMSO for 4) to investigate the solvent-chromic behavior. All these MOCs exhibit typical radical-induced chromism upon illumination with a xenon lamp at room temperature. It is worth noting that coordination solvent molecules significantly modulate the photochromic response rate. Among the compounds studied, compound 1 exhibits the fastest response, while compound 3 shows the slowest. This variation in rate correlates with differences in the optimal ET path length within their structures. Specifically, solvent molecules regulate the C–H···π interaction distance through their steric hindrance and electronic properties. Shorter C–H···π paths facilitate more efficient ET upon photoexcitation, thus leading to faster photochromic response rates. Furthermore, illumination actuates magnetic couplings between photogenerated radicals and Mn2+ centers, resulting in a significant increase in room-temperature magnetization, demonstrating a photomagnetic response. This study demonstrates that coordinating solvent selection effectively controls photoinduced ET behavior, providing new insights for designing advanced photoactive materials.
