Abstract
An electrochromic device comprises two electrodes separated by an electrolytic medium and means to permit the application of a potential between the electrodes, so as to create a circuit for charge transfer, and an electrochromic material in contact with the electrolyte and an electrode so that a change in spectral properties of the material is detectable from the exterior of the device, the electrochromic material comprising an aluminium and/or silicon containing monophthalocyanine or monotetrabenzoazaporphyrin complex.
