Photoswitching of the Dielectric Constant of the Spin-Crossover Complex [Fe(L)(CN)_2] centre dot H_2O

摘要

The interest in bistable molecular materials for information processing has been discussed by several authors.Iron(II) spin-crossover (SCO) compounds are particularly promising in this respect,because the conversion between the high-spin (HS) (S = 2) and low-spin (LS) (S = 0) states can be triggered not only by temperature,pressure,and pulsed magnetic fields,but also by irradiation with light.
