We investigate here the consequence on light-induced and thermally induced spin-crossover (SCO) properties with particle size reduction from the macroscopic to microscale to nanoscale domains. Three samples with distinct particle sizes of the SCO coordination polymer [Fe(NCS)(2)(bpe)(2)] [bpe = 1,2-bis(4 -pyridyl) ethane I have been prepared by water-in-oil reverse micelle methods. Comparison of the magnetic properties with particle size reduction of these and the original macroscale slow-grown crystals revealed that the spin transition becomes more gradual, more incomplete and concomitantly the transition temperature (T(1/2)) decreases - much like what is observed in metal dilution studies
