Abstract

The invention discloses an organic-inorganic nanocomposite two-photon fluorescent material as well as a preparation method and an application thereof. The organic-inorganic nanocomposite two-photon fluorescent material is formed by compositing an organic component and an inorganic component under interfacial coordination of Zn(NCS)2, wherein the organic component is ligand L, namely, 4-([2,2':6',2''-terpyridine]-4'-yl)-N,N-diphenylamine, and the inorganic component is ZnS. The ligand L and ZnS nanoparticles are composited under the interfacial coordination of Zn(NCS)2. The L-ZnS nanocompositematerial has the characteristics of large two-photon absorption cross section (capable of reaching 2992.08 GM), low excitation energy, high penetrability, small optical damage, low toxicity and the like and realizes long-wavelength emission, so that damage to cells is avoided, and the material can be used for detecting copper ions in living cells and has obvious application value.

Description

technical field

[0001] The invention relates to a composite two-photon fluorescent material, in particular to an organic-inorganic nano composite two-photon fluorescent material and its preparation method and application. Background technique

[0002] Organic-inorganic nanocomposites widely exist in nature, such as animal bones, teeth, egg shells, pearls, etc. are typical natural biocomposites. Organic-inorganic nanocomposites combine the excellent properties of organic, inorganic and nanomaterials, and can form important multifunctional new materials with good mechanical, optical, electrical and magnetic functional properties. They are used in many fields including in the process of life activities. have a broad vision of application. Organic-inorganic nanocomposites refer to composite materials whose dispersed phase size is less than 100nm in one dimension. The nanophase and other phases are compounded at the nanoscale through chemical (covalent bonds, coordination bonds)...
