Description
Technical Field
The invention belongs to the crossing field of coordination chemistry and nano materials, and relates to a copper-iodine cluster-based metal organic framework material for time-dependent encryption and inkless erasable printing.
Background
Inherent properties of MOFs, such as adjustable pore size, abundant guest species and ease of functionalization, can be used to initiate structural isomerisation of the responsive groups, control the extent of structural isomerisation and/or alter the fade time. The responsive groups are uniformly immobilized on the framework of the MOF material and form an ordered array, which allows for faster and more efficient energy transfer between the external stimulus signal and the reactive sites. The high porosity provides enough space for structural isomerization of the response group, which is beneficial to realizing reversible photochromism in a solid state. Has extensive research in the fields of data encryption, anti-counterfeiting, intelligent window, inkless erasable printing, biological imaging and the like.
Current research based on most MOFs-based stimuli-responsive materials only shows one input signal (external stimulus) and one output signal caused by structural isomerisation of the responsive groups, limiting their application in anti-counterfeiting and information encryption. Integrating multiple external stimuli and multiple output signals in the same architecture is critical to achieving higher level encryption of information. In particular, for information encryption materials having time dependence, it is required to display various information states on one time scale and output correct information only at a specific time, so that the requirement of higher-level information encryption can be satisfied.
The spiropyran-like stimulus-responsive smart materials undergo structural isomerisation from a colourless spiropyran to a coloured merocyanine structure due to a rapid response to external stimuli such as heat, light, mechanical forces, pH and electricity. The spiropyrans as organic bridging ligands are synthesized into Metal Organic Frameworks (MOFs) material, which can be arranged in a precise manner in a periodic lattice, providing great opportunity for creating novel solid-state stimuli-responsive materials. At present, no relevant report is found.
Disclosure of Invention
The present invention is directed to the synthesis of a copper-iodine cluster-based metal organic framework material for time-dependent encryption and inkless erasable printing.
In order to achieve the purpose of the invention, the chemical formula of the copper-iodine cluster-based metal organic framework is as follows: c (C) 60 H 51 Cu 2 I 2 N 9 O 6 /C 58 H 48 Cu 2 I 2 N 8 O 6 (abbreviated as Cu) 2 I 2 -TNDS·CH 3 CN/Cu 2 I 2 TNDS-150), belonging to the monoclinic system, the space group being I2/a,
wherein TNDS is 1',3',3 '-trimethyl-6-nitro-4', 7 '-bis (4-pyridyl) -spiro [ benzopyran-2, 2' -indoline ], and has the following structural formula:
the preparation method of the metal organic framework material is realized by the following steps:
the ligand 1',3',3 '-trimethyl-6-nitro-4', 7 '-bis (4-pyridyl) -spiro [ benzopyran-2, 2' -indoline ] is dissolved in dimethyl sulfoxide (DMSO) solution, ultrasonic treatment is carried out until the solution is clear, then cuprous iodide dissolved by acetonitrile is added, yellow massive crystals are obtained after the solution is placed at room temperature, and the crystals are filtered, washed by acetonitrile and dried at room temperature. It is treated in an oven to give acetonitrile-removed metal organic framework material.

The copper-iodine junction is connected through four pyridine bidentate ligands to form a two-dimensional layer with a diamond-shaped pore structure, and a guest molecule acetonitrile is positioned in the diamond-shaped pore (shown in figure 2). The original framework structure is maintained after acetonitrile is removed by treatment at 150 ℃ (shown in figure 3).
The time-dependent encrypted and inkless erasable printed copper-iodine cluster-based metal organic framework material has the following specific properties:
the material has excellent photochromic property, and can trigger structural isomerization from colorless spiropyran to colored merocyanine under ultraviolet irradiation (shown in figure 4), and the structural isomerization degree and retention time can be controlled by CH 3 The amount of CN guest molecules was regulated to exhibit multiple-color dynamic photochromic behavior (shown in FIG. 5). Can be used to prepare dynamic three-dimensional codes (shown in fig. 6) based on time-dependent information encryption. Furthermore, under daylight conditions, cu 2 I 2 The partial cyanine form of TNDS-150 has a very long retention time [ ]>72h) (shown in fig. 7), the produced pattern has a good color rendering (shown in fig. 8). The retention time exceeds most of the photochromic materials that have been reported.
The invention has the beneficial effects that: the metal organic framework material has a complete monocrystalline structure, and powder crystals can be stabilized to 150 ℃ to maintain the crystalline structure. Not only has solid color-changing property, but also can control CH 3 The amount of CN guest molecules is used for regulating the degree of color change and the retention time, and the dynamic photochromic behavior with multiple colors is shown.

This was treated in an oven at 150 ℃ for 4 hours to give acetonitrile-removed metal organic framework material. For further characterization and property testing.
The metal frame material of the invention prepared in example 1 was further characterized as follows:
(1) Crystal structure determination
The X-ray single crystal diffraction data of the complex was measured on a Rigaku XtaLAB Pro single crystal diffractometer using a single crystal sample of appropriate size. The data are all obtained by using CuK alpha rays which are monochromized by graphiteThe diffraction sources were collected by ω scan at 200K temperature and were subjected to Lp factor correction and semi-empirical absorption correction. The structural analysis is that the initial structure is obtained by a direct method through the SHELXS-97 program, and then the SHELXL-97 program is used for finishing by a full matrix least square method. All non-hydrogen atoms were refined using anisotropic thermal parameters. All hydrogen atoms were refined using isotropic thermal parametric methods. Detailed crystal measurement data are shown in table 1; major bond length->And bond angle (°) change data are shown in table 2.
