Chemically, biodiesel is a mixture of fatty acid alkyl esters (FAMEs) which are produced from a broad range of oil materials, such as vegetable oils, animal fats and waste oil[3].
Among the unique characteristics of ILs are negligible vapor pressure, good solubility in both organic and inorganic materials, able to form multiple phase systems due to their miscibility, and highly tunable for specific tasks[8,9].
They based on the acid anion catalyzed by acidic Ionic Liquid catalyst for high activity than other acidic Ionic Liquid, bisulfate anion main root, raw materials readily available.

They have been incorporated into a wide variety of materials and molecular architectures, including polymers and molecular glasses.
Compared with inorganic materials, conjugated organic materials are more predominant in properties such as large nonlinear optical susceptibility, fast response, high resistance to laser radiations, low dielectric constant, and ease of processing.
These nonlinear optical materials can be used with low intensity lasers for applications, such as phase conjugation, image processing, and optical switching.
Experiment Materials. 2-amino-6-nitrobenzothiazole, N-, N-hydroxyethyl aniline, Dibutylbis (lauroyloxy) tin（T-12） were obtained from Sinopharm Chemical Reagent Co.
