Engineering Magnetic Bistability: Solvent-Driven Photoresponsive Single-Chain Magnet Behavior in Fe₂Co Coordination Polymer.

ABSTRACT: Single-chain magnets (SCMs), characterized by slow magnetic relaxation, hold immense promise for future data storage and advanced materials. Integrating photoswitchable electron transfer coupled spin transition (ETCST) or spin crossover (SCO) exhibiting units has been a strategy to achieve photoresponsive SCMs. However, achieving the ETCST behavior, alongside photoresponsive switching, is challenging, and even if accomplished, it does not always guarantee SCM behavior. Here, we demonstrate solvent-directed control of magnetic behavior in isostructural cyanide-bridged Fe₂Co 1D chains of the type {[Fe-(Tp)-(CN)₃]₂[Co-(L)₂]·xA·yB}, where L = 4-nitrophenylimidazole, Tp = hydrotris-(pyrazol-1-yl)-borate, and A/B are solvent molecules.
