Abstract

The invention discloses a sulfonic acid tetraphenyl porphyrin nano-fluorescent material and a preparation method thereof, which relate to a fluorescent porphyrin material and a preparation method thereof. The sectional shape of the material is of a rectangular sheet or strip or sheet and strip. The method comprises the following steps: preparing a TPRS alcohol solution first, preparing a TPPS nano-fluorescent material dispersion system, and obtaining a product through separation and drying. The material has smaller size and better photosensitivity, has good characteristics of a porphyrin monomer such as rigidity and flexibility, electronic buffer capacity, photosensitivity, high chemical stability, wide spectral response, and also has special properties after the nanometer treatment such as small-size effect, surface effect, quantum effect, interfacial effect. The method is simple, has low production cost, and is convenient for promotion and application. The material prepared by adopting the method can be widely used as markers, photosensitive materials as well as sensitive recognition elements and materials for constructing photoelectric devices, molecular devices and sensors.

Description

technical field [0001] The invention belongs to the technical field of porphyrin nanometer materials, in particular to a porphyrin nanometer fluorescent material and a preparation method thereof. Background technique [0002] Nanotechnology is another major technology that profoundly affects social and economic development after information technology and biotechnology. Its rapid development will bring about a revolutionary change in almost all industrial fields in the 21st century. Nanomaterials have physical and chemical properties that traditional materials do not have: small size effect, surface effect, quantum effect and interface effect. So that it has some special properties that ordinary materials do not have: lead to new small size effects in physical properties such as sound, light, electromagnetic, and thermodynamics; as the particle diameter becomes smaller, the specific surface area will increase significantly. Such a high specific surface makes the number of a...
