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 photoelectric material based on a pillar aromatic hydrocarbon supramolecular polymer, a preparation method and an application thereof. The supramolecular polymer photoelectric material contains A1 unit and A2 unit, and functional groups B and C connected to A1 and A2 respectively, and the A1 and A2 units are oligomers containing conjugated units or small molecular groups containing conjugated units The functional group B is a pillar arene, the functional group C is a neutral alkylimidazole, and the functional groups B and C are connected by multiple C‑H···O(N) hydrogen bonds and C‑H···π interactions. The invention reduces the conditional selectivity of supramolecular polymer formation by introducing pillar arene structure unit of novel macrocyclic supramolecular host material. The invention expands the application of supramolecular polymer optoelectronic materials by introducing different functionalized oligomers.

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 prospect. 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.] re...
