Photoconduction in [Fe(Htrz)2(trz)](BF4)·H2O nanocrystals

Sub-micron-sized [Fe(Htrz)2(trz)](BF4)·H2O nanoparticles that exhibit a spin crossover transition are positioned between Au electrodes with sub-100 nm separation. After voltage poling, samples exhibit unexpected large conductivity, with photoconductance and photovoltaic behavior.
