Document Type and Number:
WIPO Patent Application WO/2023/071855
Kind Code:
A1
Abstract:
Disclosed are a class of hydrazone-based Zn (II) coordination complex photochromic material, a preparation and a use thereof. Said class of material is a hydrazone-based terpyridine ligand, hydrazone is used as a basis of an optical switch, terpyridine is used as a receptor at one end of the hydrazone, and methoxyl or p-dimethylamino is used as a donor at the other end to form a push-pull system to regulate and control the optical switch, achieving an effective optical switch thereof and emission on/off switching. On the basis of the foregoing, the mutual electrostatic interaction between metal ions and counter ions may be adjusted by means of coordination with different zinc salts, so that the photophysical properties of thereof are regulated and controlled, and luminescence of different colors is achieved. Said class of material displays, under the stimulation of an external light source, excellent photochromic performance and emission on/off switching capability. By utilizing said characteristic, a rewritable photochromic device may be obtained, and the photochromic device is expected to be widely used in the field of photoelectric information storage.
