Abstract
The invention provides a third-order nonlinear optical material, namely a tetrabutyl ammonium fullerene ball and a synthesizing method thereof, which belongs to the field of functional materials. The prior inorganic and organic nonlinear optical materials have the problems of easy deliquescence, poor thermal stability, complicated preparation and the like respectively. The molecular formula of the tetrabutyl ammonium fullerene ball provided by the invention is (NH4)18[(C16H36N)4]24[Mo132O372(H2O)72(CH3COO)30].ca.7NH4CH3COO.ca.173H2O. In the method, after {Mo132} and tetrabutyl ammonium bromide are dissolved in water respectively according to the mass ratio of 1 to 42, and are adjusted by acetic acid respectively until the pH value is between 3.5 and 4.5, the {Mo132} and the tetrabutyl ammonium bromide are mixed to obtain the tetrabutyl ammonium fullerene ball. The third-order nonlinear optical material has the advantages of uneasy deliquescence, high thermal stability, larger nonlinear absorption and non-linear refraction coefficient, self-defocusing property and simple preparation.
Description
Technical field
The invention belongs to field of functional materials, be specifically related to a kind of hybrid inorganic-organic third order non-linear optical material and synthetic method thereof.
Background technology
Nonlinear optical material has important use and is worth at aspects such as optical Information Processing, all-optical switch, photometry calculation, optical communications.Third order non-linear optical material is to realize all-optical switch, photometry calculation and the complex conjugate basis of phase place, the efficient of the full optical device of the high bit rate data processing of series and parallel, the performance of used third-order non-linear material when depending on the optical signal coupling.Mineral crystal is the nonlinear optical material that is studied the earliest, and has been applied in the development of device, but the inorganic nonlinear optical material time of response is long, and preparation technology is difficulty, can select kind single, easily drawbacks limit such as deliquescence its application.In recent years, the third-order nonlinear optical character of organic compound material becomes the focus of research, and the material of reporting in the document has poly-sulphur benzene, ferrocene deriv etc. to grip organic polymer, soccerballene, semi-conductor and cluster compound etc. altogether.Organic molecule, superpolymer nonlinear optical material are big because of having nonlinear optical coefficients, transparent wavelength range is wide, and intrinsic is short switching time, the optical damage threshold height, advantage such as good processability and receive scientific research person's concern, but shortcomings such as poor heat stability, synthetic complexity but had.
Summary of the invention
The objective of the invention is to solve the problems of the prior art, a kind of deliquescence, synthetic method is simple, thermostability is high hybrid inorganic-organic third order non-linear optical material and synthetic method thereof of being difficult for is provided.
