Abstract

The invention provides a copper cluster two-photon absorbing material with a living cell developing function, which is a univalent copper cluster with a multi-branched general chemical formula. The copper cluster two-photon absorbing material is prepared by the steps of: firstly, preparing a pyridine ligand from 4-methylpyridine and 4-N,N-2R-aminobenzaldehyde; and secondly, synthesizing a target product by using the pyridine ligand and cuprous iodide.

Description

1. Technical field [0001] The invention relates to a two-photon absorbing material and a preparation method thereof, in particular to a copper cluster compound two-photon absorbing material with low toxicity and a living tissue cell developing function and a synthesis method thereof. 2. Background technology [0002] In recent years, with the discovery of two-photon absorbing materials, two-photon fluorescence technology has made a major breakthrough in its application. Since the two-photon technology uses long-wavelength excitation (near-infrared), it has the characteristics of low excitation energy, long wavelength, strong penetration, and small photodamage. It has attractive application prospects in medical diagnosis and fluorescence microscopy imaging. In 2004, O'Halloran (J.Am.Chem.Soc., 2004, 126, 712-713) reported the use of Zn(II) ion-centered complex two-photon fluorescence microscopy in the detection of living tissue cells The application of this method has succes...
