Abstract

The invention discloses a poly-(phenyleneethynylene)-zinc phthalocyanine polymer with an optical limiting effect, and a method for preparing the polymer. The method comprises the following steps: A, preparing a polymer PPE (polyphenyl ether); B, preparing a polymer PPE-COOH; C, preparing a polymer PPE-COCl; and D, preparing a polymer PPE-ZnPc, namely, the poly-(phenyleneethynylene)-zinc phthalocyanine polymer. The invention further discloses an application of the poly-(phenyleneethynylene)-zinc phthalocyanine polymer with the optical limiting effect as a nonlinear optical material or a laser protection material. The polymer disclosed by the invention is provided with an augmented pi electron conjugated system, and is a good nonlinear optical material; according to the preparation method of the poly-(phenyleneethynylene)-zinc phthalocyanine polymer disclosed by the invention, zinc phthalocyanine is covalently grafted on a main chain of polyphenyleneethynylene as a lateral group by virtue of amidation, thus avoiding the separation of the polymer.

Description

technical field [0001] The embodiment of the present invention relates to a poly-(phenylene vinylene)-phthalocyanine zinc polymer with optical limiting effect and its preparation method and application, belonging to the technical field of organic nonlinear optical materials. Background technique [0002] As an important means in modern high-tech warfare, laser technology has been widely used in the military field. Because of its high directivity, high monochromaticity, high brightness and other characteristics, laser has attracted great attention from military personnel in various countries. Various low-energy laser weapons, such as laser radar, laser blinding weapons, etc., will not only interfere with and destroy the photoelectric sensors of the equipment, but may also blind the human eye; while high-energy laser weapons use laser beams as energy carriers, using the high-energy laser The seriousness of the threat of directly destroying the target is self-evident. Therefo...
