Title:
PHOTOINDUCED NONLINEAR EXPANSION COORDINATION POLYMER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/077654
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of photosensitive materials, and particularly relates to a photoinduced nonlinear expansion coordination polymer and a preparation method therefor. The coordination polymer is a luminous yellow bulk crystal and has a chemical formula of [Zn(iba)(tkpvb)Cl]n1, wherein iba denotes p-iodobenzoate, tkpvb denotes 1,2,4,5-tetra((E)-2-(4-pyridyl)vinyl)benzene, and n = 3,000-60,000. Crystallographic parameters are: (1) crystal system: monoclinic system; (2) space group: Cc; (3) a=28.6156(16)Å, b=7.2901(4)Å, c=21.5157(13)Å, β＝127.430(4)°, and V=3574.2(4)Å3; (4) Z＝4; and (5) F(000)＝1680, R
1＝0.1363, wR
2＝0.3788, and GOF＝1.620, wherein iba denotes p-iodobenzoate, tkpvb denotes 1,2,4,5-tetra((E)-2-(4-pyridyl)vinyl)benzene, and n1 = 3,000-60,000. The preparation method for the coordination polymer of the present invention is simple, reaction conditions are mild, and the light conversion rate is high; in addition, an addition reaction can occur under the irradiation of light with different wavelengths, so as to present the photoinduced nonlinear expansion performance of the material and obtain a corresponding isomer compound.
