For the complex TPE-TPy-Pt-Cl, the ultraviolet absorption peak at 421nm in tetrahydrofuran occurs due to the molecules undergoing a charge transfer transition from platinum (II) to the ligand TPE-TPy [ dpi (Pt) →pi (TPy), MLCT]Is caused by the process in which the ligand-to-ligand charge transfer transition characteristic [ pi (TPE) →pi (TPy), LLCT also occurs]This process is called MLCT/LLCT. When poor solvent water was gradually added to the above solution, the ultraviolet absorption peak of the complex TPE-TPy-Pt-Cl at 421nm gradually decreased, while when the water content in the mixed solvent reached 80%, the ultraviolet absorption peak at 421nm was significantly decreased, accompanied by the formation of a red-shifted peak (lambda) max =456 nm), which is commonly referred to as metal-ligand charge transfer (MMLCT). This feature suggests the possibility of ground state aggregation and Pt.. Pt or pi-pi stacking interactions in high non-solvent content media. This suggests that the complex undergoes a self-assembly process in a non-solvent medium, resulting in the formation of Pt.. Pt or pi-pi stacking interactions. The ultraviolet absorption peak at 287nm is attributed to the spin transition [ pi→pi ]]。

Complex TPy-Pt-NC-Ph/PF 6 (namely, complex 9) in a system of water/acetonitrile and water/ethanol, after 48 hours, only a self-assembled body was generated in pure water, and as shown in fig. 1 a), complex 9 was assembled into a self-assembled body having a very large length and diameter in pure water, the diameter was about 4500nm (fig. 1 b), and the luminescence color was yellow (fig. 1 c). By analysis of the X-ray diffraction of the complex 9 in a powder state and in the assembly in pure water to produce precipitation, we can obtain a strong and sharp diffraction peak of the self-assembly produced in pure water as shown in FIG. 2, which indicates that the molecules of the complex 9 are indeed aligned in a more orderly direction in pure water, and self-assembly occurs.
The following is a complex TPE-TPy-Pt-NC-Ph/PF prepared in example 4 above 6 (i.e., complex 4 c) was studied for self-assembly properties.
Preparation of the samples: weigh 2mg of TPE-TPy-Pt-NC-Ph/PF 6 This was dissolved in 2mL of acetonitrile solution as a mother liquor. The solution systems shown in tables 1 and 2 were configured. The specific operation is as follows: according to table 1 (table 2), mixed solutions of acetonitrile (ethanol) and water in different proportions were prepared, and the mother liquor was added and mixed uniformly, followed by standing for 24 hours.
TABLE 1 Complex TPE-TPy-Pt-NC-Ph/PF 6 Assembly test under acetonitrile/water system
TABLE 2 Complex TPE-TPy-Pt-NC-Ph/PF 6 Assembly test under ethanol/water System
Dropping the sample onto a silicon wafer, sucking away excessive solution, drying overnight in an oven, and then carrying out Scanning Electron Microscope (SEM) test on the sample; the same sampling method, the sample is dripped on a copper mesh covered with thin pure carbon, and then a projection electron microscope (TEM) test is carried out on the sample; similarly, the sample was dropped onto a round quartz plate, and the excess solution was sucked away with filter paper, and subjected to a fluorescence microscope test.
For complex 4c at H 2 Self-assembly in O/ACN systems was studied. A series of samples were prepared according to Table 1, and after standing for 24 hours, it was found that precipitates were present in the pure water and acetonitrile/water 1/9 samples, and the test results obtained by SEM and TEM were shown in FIGS. 3 a-b and c-d, respectively, and it was found that the self-assembled body morphology of the complex 4c obtained by self-assembling in the pure water and acetonitrile/water 1/9 system was a regular solid pellet, and the diameters of the pellets were 500-600nm and 200-300nm, respectively.
A series of samples were prepared according to Table 2, and after 24 hours of standing, it was found that in addition to precipitation in pure water, precipitation was observed in both ethanol and water/ethanol at 9/1 and 8/2, the morphology was observed by SEM, and in ethanol, a regular shape flake (as shown in FIG. 4) was observed in water: ethanol=8:2 in the solvent, the irregularly shaped flakes (shown in fig. 5), while water: ethanol=9: 1 are folded sheets (as shown in fig. 6). Namely, the difference of the polarity and the solubility of the solvent can affect the acting force and the speed in the self-assembly process, thereby having the regulation and control function on the appearance of the self-assembly body.
The self-assembly in ethanol was studied by TEM, the lamellar structure of which can be seen from fig. 7, the region being enlarged, the presence of the crystal lattice of which can be seen clearly (as shown in fig. 8), and the crystallinity of which can be seen to be high by selective electron diffraction (SAED) (as shown in fig. 9); (e and f in FIG. 10 are SAED patterns of self-assembly of complex 4c in water, acetonitrile/water 9/1, respectively), it is clear that: the good crystallinity of complex 4c in ethanol systems compared to complex 4c in water, acetonitrile/water 9/1 systems suggests that compound 4c does self-assemble into a sheet structure in ethanol, whereas it is a sphere structure in water, acetonitrile/water 9/1 systems. .
Meanwhile, as shown in fig. 11, the complex 4c only has a very weak diffraction peak at 22 degrees in the powder state, the precipitate generated after the complex 4c self-assembles in the water system has stronger diffraction peaks at 7 degrees and 22 degrees, and the precipitate generated after the complex 4c self-assembles in the ethanol system has diffraction peaks at 7 degrees, 10 degrees, 12 degrees, 15 degrees, 20 degrees, 22 degrees and 25 degrees, which indicates that the precipitate generated by the complex 4c self-assembles in the ethanol system (namely, self-assemblies) has better crystallinity, which is consistent with the phenomenon.
For the crystal structure of complex 4c, as shown in FIG. 12, after modification of complex 3, the tetraphenyl ethylene moiety still has a large distorted structure in the molecule, and the dimethyl benzene linked to the isocyanide is also non-coplanar with the terpyridine-platinum moiety, with two anions (hexafluorophosphate groups) on either side of the terpyridine. The distance between platinum and platinum reachesThe anions in the molecule are just positioned between two adjacent terpyridine planes, wherein F-H interaction is generated between the fluoride ions in the hexafluorophosphate radical and the hydrogen ions on the benzene ring, so that the molecules have stronger interactionThe function is achieved, so that a good self-assembly effect can be achieved.
Four different anion complexes (4 a-4 d) are obtained by adopting a triple bond to modify the complex TPE-TPy-Pt-Cl, so that the obvious improvement of the luminous quantum efficiency and the regulation and control of the luminous wavelength are realized. And then, the target product is subjected to self-assembly research, and the regulation and control of different morphologies of the self-assembly body are realized through the regulation and control of the solvent. Because the existence of tetraphenyl ethylene in the molecular structure breaks the platinum-platinum interaction, anions can be just embedded between molecules to drive the ordered arrangement of molecules through the anion-pi interaction, and the method provides a feasible strategy for constructing self-assemblies with different morphologies.
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
