Abstract

The invention relates to a POSS (Polyhedral Oligomeric Silsesquioxane) hybridized squarine near-infrared absorption dye, which at least comprises a POSS monomer of an active group and a halogenated squarine monomer. A preparation method of the dye comprises the following steps: in the nitrogen gas atmosphere, adding the POSS monomer and the halogenated squarine monomer in a mixed system of a catalyst, an acid-binding agent, a ligand and organic solvent; and carrying out an addition or polymerization reaction at the temperature of 130-140DEG C for 10-25h to obtain the POSS hybridized squarine near-infrared absorption dye. The POSS hybridized squarine near-infrared absorption dye has the advantages of stronger near-infrared absorbing performance, favorable heat, light and chemical stability and favorable aggregation resistance and material compatibility. The preparation method is simple and feasible, has favorable economic benefit, is applicable for industrial production and can be widely applied to the fields of nonlinear optics, photodynamic therapy, optical data storage, laser printing, biological probe, near-infrared photographing, solar cells and the like.

Description

Technical field [0001] The invention belongs to the field of near-infrared absorbing squaraine dye and its preparation, and particularly relates to a POSS hybrid squaraine near-infrared absorbing dye and a preparation method thereof. Background technique [0002] Near-infrared light refers to electromagnetic waves with wavelengths between 700 and 2500 nm, that is, the intermediate band of ultraviolet-visible and mid-infrared analysis. Since there are few materials that absorb near-infrared light, near-infrared light suffers little interference in the propagation process and has good transparency to materials. It is a new optical field with unique functions. Near-infrared technology plays an important role in the study of the interaction between near-infrared light and matter, and plays an important role in military reconnaissance, infrared camouflage, material analysis, medical detection, photosensitive, photopolymerization, nonlinear optical materials, solar cells and other fiel...
