Problems solved by technology

Some existing studies have reported the modulation of linear micelles formation or destruction conditions that directly act as photosensitizers, and these are mostly based on cetyltrimethylammonium bromide and azobenzene-containing amphiphile mixtures [H. Sakai, Y .Orihara, H. Kodashima, A. Matsumura, T. Ohkubo, K. Tsuchiya, M. Abe, J. Am. Chem. Soc. 127 (2005) 13454–13455] or cinnamic acid der

Abstract

The invention relates to a photosensitive mixed surfactant and a preparation method and application thereof, in particular to a photosensitive mixed surfactant based on a stilbene cation mixed surfactant represented as CFm StilCHn, CFm represents a perfluorohydrocarbon chain segment with the carbon atom number of m (m = 4, 6, 8), Stil represents diphenylethylene, CHn represents an alkane chain with the carbon atom number of n (n = 1, 4, 8), and the surface and micellization properties of the surfactants are researched. In the most meaningful property, due to the existence of a fluorocarbon chain, the stilbene-based mixed surfactant shows remarkable surface activity on the surface tension of a water/air interface. In addition, ultraviolet irradiation enables the surface tension of an air/water interface to be obviously increased, and compared with a traditional stilbene-based surfactant, the mixed surfactant cis/trans-isomer has larger surface tension difference.

Description

technical field [0001] The invention belongs to the technical field of surfactants, in particular to a photosensitive mixed surfactant, its preparation method and application. Background technique [0002] In photochemical reactions, photochromism is the reversible photoswitching of two forms when a substance is exposed to heat or light, and these two forms have different absorption spectra. Photoisomerization not only changes the absorption spectrum of the substance, but also affects the physical and chemical properties of the substance, such as refractive index, redox site and geometric structure. These properties have been applied in many fields such as liquid crystals, photochemical recording, molecular switching devices, micellar catalysis, photoelectric foams and gels. Recently, researchers have applied photochromism to biological systems and polymer preparation. [0003] Stilbenoid, a photochromic material, switches between two isomers depending on the wavelength of...
