Problems solved by technology

[0004] Although the previous researchers have achieved great success, there are still many difficulties in the research from molecules to materials, from molecular properties to material functions, especially the disordered aggregation of molecules in materials causes the nonlinear optical response of materials. Quenching, how to develop nonlinear optical materials with better performance is still a challenge for researchers in this field

Embodiment 1

[0030] Embodiment 1: the preparation of self-assembled nanofiber material

[0031] Add 5,15-ferrocenyl zinc porphyrin (0.1122 g, 0.15 mmol) and 4,4'-bipyridine (0.1171 g, 0.75 mmol) into 60 mL of chloroform solution and stir to dissolve, then slowly add methanol solution 300mL, placed in a flask, sealed, and left to stand for 60 h. The resulting product was washed with methanol, centrifuged and dried at 60°C in vacuum for 6 h to obtain 0.1390 ​​g of self-assembled porphyrin nanofiber material. The scanning electron micrograph of the obtained self-assembled porphyrin nanofiber material is as follows: figure 1 Shown; The XRD pattern of self-assembled porphyrin nanofiber material is as image 3 shown.

Abstract

The invention belongs to the technical field of organic non-linear optical materials, and particularly relates to a self-assembly porphyrin nano fiber material. Experiment data show that the self-assembly porphyrin nano fiber material has a regular appearance shape, is bar-shaped or strip-shaped, has high hyperpolarizability, has the characteristic of reverse saturable absorption and can be applied to non-linear optical and laser protection.

Description

technical field [0001] The invention belongs to the technical field of organic nonlinear optical materials, specifically relates to a self-assembled nanofiber material, and discloses its preparation method. The nanofiber material has a high hyperpolarizability and shows reverse saturation absorption characteristics. Can be used in nonlinear optics and laser protection. Background technique [0002] With the advent of lasers, nonlinear optics (NLO) has developed rapidly. Nonlinear optics mainly studies the interaction between strong light (such as laser) and matter. When the light reaches a certain intensity, the absorption of light by matter no longer conforms to the laws given by traditional optics, and its absorption coefficient will change with the Vary with changes in light intensity. Nonlinear optical materials have great potential application value in optical communication, high-speed photoelectric information processing, high-density data storage, short optical puls...
