Lithographically organized 1D nano-tape arrays composed of solution processable above room temperature spin cross-over Fe(II) coordination polymer

A novel, highly soluble and solution processable Fe(II) spin cross-over (SCO) coordination polymer shows an SCO temperature at T-1/2 similar to 302 K. Bottom-up self-assembly of this supramolecular polymer in THF-water formed a several micron long nano-tape network. Further solution processing using a lithographically controlled wetting technique produced aligned 1D arrays of SCO nano-tape bundles.
