Abstract

The invention relates to the technical fields of luminous material, two-photon absorption material, optical storage and the like, in particular to two-photon induced luminous compound with symmetrical both ends and a synthesis method and purposes thereof. Raw material sodium methoxide is added into N, N-DMF solvent which is dissolved with phosphate reagent to be uniformly stirred, and then aldehyde is added in to react; the reaction solution is poured into water and filtered; the prepared hot ethanol for residue is filtered; and chromatographic separation is carried out to the rest solid, andthe two-photon induced luminous compound with symmetrical both ends is prepared. After being doped into an epoxy resin solid matrix, the two-photon induced luminous compound with both ends symmetrical prepares strong two-photon induced luminous solid material which can be used for fluorescent probes or fluorescence imaging material. The two-photon induced luminous compound with symmetrical both ends of the invention is a type of two-photon induced luminous 1, 2, 2 and 4-tetramethyl-dihydro-quinoline compound with both ends symmetrical, and the structure of the two-photon induced luminous compound is shown as the accompanying drawing.

Description

technical field [0001] The invention relates to the technical fields of luminescent materials, two-photon absorbing materials and optical storage, and in particular to two-photon-induced luminescent compounds with two-terminal symmetry and their synthesis methods and applications. Background technique [0002] Luminescent materials refer to materials that can emit visible light after being excited by various energies. Such materials have been widely used in high-tech fields such as flat panel displays, lasers, optical lighting, and biomolecular probes. In today's information age, the development of luminescent materials that can meet various information display requirements is particularly rapid. Organic light-emitting materials are mainly composed of organic substances, which have the advantages of easy adjustment of properties through structural modification, easy purification and low cost, and have the advantage of easy large-area film formation. Two-photon induced lumi...
