The invention relates to an acridine compound, a polymer, an application thereof, and a light-emitting device. The structural formula of this acridine compound is shown in formula (I): wherein, n 1 ~n 4 independently choose 0 or 1, and n 1 ~n 4 Not 0 at the same time; D 1 ~D 4 are independently selected from: a substituted or unsubstituted arylene group, or a substituted or unsubstituted heteroarylene group. In the invention, the acridine unit connected by spiro structure is used as the core, the arylene group and the heteroaryl group are used as the arms, and the vinyl unit is used as the terminal to construct the acridine compound. The compound is soluble in conventional solvents at room temperature, and due to the electron-donating conjugation of the nitrogen atom in the acridine unit, the electron cloud density of the entire acridine unit is relatively high, making it a good unit for transporting holes; its terminal It is a vinyl unit, cross-linked at high temperature to form a cross-linked layer that is not easily soluble in conventional solvents, and is not easily dissolved by the solvent of the next functional layer, which is beneficial to improve the luminous efficiency.

The invention relates to a fiber composite multi-layer total fluoride crosslinking ionic membrane and a preparation method thereof, which belongs to the field of functional polymer composite materials. The fluorine-containing ion exchange membrane is in a double-net structure with chemical bonding crosslinking and physical bonding crosslinking of a high valent metallic compound and an acidic exchange group and simultaneously contains reinforced fiber. The prepared ion exchange membrane has higher dimensional stability and good mechanical strength.

The invention relates to a multi-layer cross-linking ion membrane generated from perfluor ion-exchange resin, belonging to the field of functional polymer composite materials. At least one layer of the multi-layer cross-linking ion membrane has a cross-linking reticular structure, and at least one layer of the multi-layer cross-linking ion membrane contains high-valence metallic compounds; moreover, high-valence metallic compounds are added to the multi-layer cross-linking ion membrane, so that the high-valence metallic compounds and the acidic exchanging groups in the resin can physically bonded. Accordingly, the invention further improves the stability and mechanical properties of the multi-layer cross-linking ion membrane and particularly improves the performance in gas permeation prevention.

The invention provides a laminated silicon dioxide microsphere and a preparing method thereof. The preparing method is simple, and the laminated silicon dioxide microsphere can be prepared within 3-4h. A hydroxyl compound coats the surface of silicon dioxide through the hydroxylation effect, then in the emulsification process, through a dispersing agent, mutual cementation of coated silicon dioxide is effectively avoided, and the dispersity is improved; then through the further utilization of emulgator, the surface tension of coated silicon dioxide is lowered, a protection layer can be formedon the surface of coated silicon dioxide, and cohesion of coated silicon dioxide is further prevented. Under the effect of a catalyst, the hydroxyl compound coating the surface of silicon dioxide issubjected to an aldolization reaction with an aldehyde group cross-linking agent, cross-linking of the aldehyde group cross-linking agent and the hydroxyl compound is achieved, and then a product which is obtained through the aldolization reaction of the cross-linking agent and the hydroxyl compound is formed on the surface of silicon dioxide.
