摘要
(Figure Presented) Photoswitching of the dielectric constant has been observed for the first time in the spin-crossover complex [Fe(L)(CN) 2]·H2O (L = 2,13-dimethyl-6,9-dioxa-3,12,18- triazabicyclo[12.3.1]octadeca-1(18),2,12, 14,16-pentaene, see picture). The electrical detection of a photoinduced change in spin state could allow the use of such complexes in optical information-storage devices. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
