摘要：
(Figure Presented) Nanocrystals of the three-dimensional, spin-crossover, porous coordination framework [Fe(pz)Pt(CN)4]·nH2O (pz = pyrazine; n ≤ 2.5) have been synthesized from water-in-oil microemulsions. The surfactant-free nanocrystals readily desorb water and the resulting anhydrous compounds exhibit thermally induced electronic bistability accompanied by a pronounced color change (see picture; HS = high spin, LS = low spin) close to room temperature. © 2008 Wiley-VCH Verlag GmbH & Co.
