Abstract

A novel highly soluble spin-crossover (SCO) [Fe^II(L) ₂](BF₄)₂ complex (I) was prepared, where L = 4,4″-dioctylated 2′,6′-bispyrazolylpyrine. Complex I shows reversible temperature dependent SCO behavior with a T_1/2 centered around 270 K. Exploiting the high solubility and hence superior processability of complex I nano/micro scale arrays and square patterns were fabricated on a glass substrate. Additionally, for the first time, for the possible flexible technological applications, the SCO arrays (area: 2 mm²) were successfully embedded within an optically transparent thin polystyrene film and studied using Raman spectroscopy/imaging technique. Variable temperature Raman spectroscopy studies further confirmed the SCO behavior of complex I.
