Patent ID: 11976087

Abstract:
The invention provides a light-stimuli responsive coordination polymer, and preparation method and use thereof. The coordination polymer has a chemical formula of [Zn(tkpvb) (Fb)2]n1, wherein Fb represents p-fluorobenzoate, tkpvb represents 1,2,4,5-tetrakis((E)-2-(4-pyridyl)vinyl)benzene, and n=3000-60000; and crystallographic parameters of: (1) crystal system: monoclinic system; (2) space group: C2/c; (3) a=28.577(3)Å, b=7.4084(6) Å, c=22.612(3) Å, β=126.771(2)°, and V=3834.8(7) Å3; (4) Z=4; and (5) F(000)=1720, R1=0.0440, wR2=0.1042, and GOF=1.047. The method is simple, and has mild reaction conditions, and fast light conversion rate. The means of light-stimuli responsiveness are non-contact and non-damage type, the volume adjustment is highly accurate, and the whole adjustment process does not require any chemical reagents, and is safe and reliable. Photoactuators can complete a variety of behaviors under the irradiation of ultraviolet light having a wavelength of 365 nm.
