Embodiment 1

[0045] Pillararene monomer 7,7"-bis(pyra[5]arene)-2,2':7',2"-tris(9,9-dioctylfluorene)(I), 1,1'-{ [2,2':7',2"-tris(9,9-dioctylfluorene)]-bis(1,4-phenyl)}bis(oxy)bis(hexane-6,1diyl) Preparation of bis(1H-imidazole)(II)

[0046] The synthetic route is as follows:

[0047] Preparation of pillar arene monomer 7,7"-bis(pillar[5]arene)-2,2':7',2"-tri(9,9-dioctylfluorene) (I):

[0048]

[0049] Add monofunctionalized 1-bromooctyloxy-4-methoxy-pillar[5]arene (1.76g, 2mmol), cesium carbonate (3.94g, 12mmol), and add 30mL of N,N-dimethyl base formamide. Heated to reflux for 24h. The reaction was left to room temperature, dichloromethane was added, extracted, the organic layer was washed with water, and the organic phase was combined. This step was repeated three times. After drying over magnesium sulfate, the solvent was removed. It was eluted with a mixed solvent of petroleum ether / dichloromethane with a volume ratio of 1:1 as the eluent, and then separated by silica gel chromatog...

Abstract

The invention provides a pillararene-based supramolecular polymer photoelectric material, a preparation method therefor and an application of the supramolecular polymer photoelectric material. The supramolecular polymer photoelectric material contains a unit A1, a unit A2, a functional group B and a functional group C, wherein the functional groups (B and C) are separately connected with the A1 and the A2; and the units (A1 and A2) are conjugate unit containing oligomers or conjugate unit containing micromolecular ingredients, the functional group B is pillararene, the functional group C is neutral alkylimidazole, and the functional group B and the functional group C are connected through interaction between a plurality of C-H...O(N) hydrogen bonds and C-H...[PI]. Through introducing a novel macrocyclic supramolecular main body material, i.e., a pillararene structural unit, the condition selectivity of forming of a supramolecular polymer is lowered. Through introducing different functionalized oligomers, the application of the supramolecular polymer photoelectric material is extended.

Description

technical field [0001] The invention relates to the technical field of organic optoelectronic materials, in particular to optoelectronic materials based on pillar arene supramolecular polymers and their preparation methods and applications. Background technique [0002] Due to its high brightness, light weight, low operating voltage, thin device thickness, and wet processing methods such as spin coating or inkjet printing, organic light emitting diodes have a wide range of applications in the fields of flat panel display and organic lighting. Application prospects. Since 1987, Deng Qingyun Research Group [Tang, C.W.; Van Slyke S.A.et.al; Appl. Phys. Lett. 1987, 51, 913.] of Kodak Company of the United States invented the organic small molecule thin film electroluminescent device with a sandwich device structure, In 1990, the R.H.Friend research group of the University of Cambridge [Burroughes, J.H.; Bradley, D.D.C.; Friend, R.H; Holmes, A.B. et al; Nature 1990, 347, 539.] r...
