Soft Lithographic Patterning of Spin Crossover Nanoparticles

Microtransfer molding has been used to fabricate homogeneous micropatterns and nanopatterns of spin crossover nanoparticles of [Fe(NH(2)trz)](tos)(2) over a large area. We show that the use of an aprotic solvent (n-octane) may lead to successful results. Very well organized micropatterns are obtained, showing spin crossover phenomenon. Dark field optical and AFM images and Raman microspectrometry results are reported.
