Abstract
A process for synthesizing polytriphenylamine as electric hole conducting material from triphenylamine includes such steps as solid-phase grinding under existence of Lewis acid, separating and purifying. Its advantages are simple process, low cost, high output rate and no environmental pollution.
Description
Technical field
The present invention relates to a kind of synthetic method of polymer of poly-triphenylamine, belong to chemical field.
Background technology
Polymer of poly-triphenylamine is widely used in as a kind of effective hole transport compound in electroluminescent and other electrooptical device.The dimer of triphenylamine, polymer, star compound or all can be used as the hole transmission layer of electroluminescent device with the multipolymer of other aromatic molecules.The method of synthetic poly triphenylamine hole material has the Grignard reagent method, Liv Ullmann (Ulman) reaction method, oxidative coupling method, electrochemical oxidation method etc.The synthetic poly triphenylamine in laboratory Grignard reagent method commonly used, but because of its synthesis condition harshness, the loaded down with trivial details and difficult suitability for industrialized production that is used for of synthesis step.Document Chemistry letter, pp1145-1148,1989 have reported with the copper powder to be catalyzer, and three iodo triphenylamine condensations obtain product, and productive rate is 19%.Document Chemical Communications, pp2063-2064,1997 reports get the dendroid product with three bromo triphenylamine polycondensations, have good solubility.European patent EP 0802173A1 is a catalyzer with palladium and trialkyl phosphine, and three bromo triphenylamine condensations obtain product, have improved productive rate.But raw material and catalyzer are all very expensive.Chinese patent application number is the preparation method that 99119031.9 patent application discloses a kind of star hole transfering material, at first with raw material triphenylamine, halogenating agent iodine or bromine, catalyzer aluminum chloride and solvent methyl-sulphoxide, halogenating reaction is carried out in intensification, products therefrom and 3 methyl diphenylamine are as raw material, with Palladous chloride and triphenyl phosphine is the Preparation of Catalyst star hole transfering material, and its productive rate can reach 50%.Used halogenating agent iodine of this method or bromine price are higher, and the toxicity of bromine is bigger, easily contaminate environment.And use tellurian narrow resources precious metal palladium.This laboratory once used the oxidative coupling method under liquid-phase condition, with the triphenylamine is raw material, reaction obtains poly-triphenylamine in the presence of lewis' acid, simplified synthetic method, improved polymerization yield rate (Chinese patent ZL02139146.7,2004,9,29 authorize), but this method need be used the noxious solvent trichloromethane, reaction times is longer, and productive rate is still not high enough.
Summary of the invention
For solving the variety of issue that exists in the above-mentioned prior art; the invention provides the method for the synthetic polymer of poly-triphenylamine hole mobile material of a kind of solvent-free solid-state synthesis method; this method is a green synthesis method, can not only improve combined coefficient, and helps environment protection.
Technical scheme of the present invention is: be raw material with the triphenylamine, in the presence of the catalyzer lewis acid, fully grind in 5 ℃～50 ℃ solid phases and promptly to obtain the thick product of polymer of poly-triphenylamine that separation and purification obtains the poly-triphenylamine straight product.
Wherein the catalyzer lewis acid can be iron trichloride, aluminum chloride or dichloride copper, catalytic amount be raw material amount 1.5-6 doubly.
Method proposed by the invention is monomer with the triphenylamine, single step reaction obtains the triphenylamine polymkeric substance, with above-mentioned be that monomer is compared through the method that condensation polymerization obtains the triphenylamine polymkeric substance with three iodo triphenylamines, three bromo triphenylamines, do not have the halogenating reaction of triphenylamine, saved halogenating agents such as iodine, bromine; As catalyzer, the reaction times shortens without the precious metal palladium title complex, has reduced production cost.It not merely possesses the advantage of liquid oxidatively coupling method, has more advantage than liquid oxidatively coupling method.Compare with the liquid oxidatively coupling method, do not use solvent in its reaction process, reduced environmental pollution; Without secluding air, the reaction times shortens, and has simplified synthetic method again; Polymer yield can reach 90%, and is all higher than the productive rate of existing poly-triphenylamine synthetic method, makes its suitability for industrialized production become more feasible.
Therefore the present invention have step simple, easy to operate, save time, pollution, easily mass-produced that good product quality, productive rate height, preparation process have been eliminated solvent chloroform, have the distinguishing feature of industrial application value.
And the nuclear magnetic resonance spectrum CMNR of the equal poly-triphenylamine of products therefrom of the present invention shows that clearly the selectivity of polyreaction is very high, and the response location of triphenylamine occurs over just the nitrogen-atoms contraposition, and product has tree structure.Thereby not needing to introduce alkyl as the hydrotropy group, the polymkeric substance of gained has good solvability, can spin-coating film be processed into device.
