specific Embodiment approach 1

[0045] Specific embodiment one: the structural formula of the polyaniline derivative of the present embodiment is as follows:

[0046] In the formula, n is a positive integer, and Ar is

[0047] The polyaniline derivatives of this embodiment use propeller-type triarylamine as a monomer, which can effectively reduce the strong force between polymer molecular chains and increase the solubility of the polymer. At the same time, triarylamine is easy to form cationic radicals and presents a Different from the triarylamine in the neutral state, and because the structure contains two monomer units, the polyaniline derivatives have color tunability due to the joint action; on the other hand, the synthesis of the usual light-emitting or color-changing polymers requires expensive raw materials , harsh synthesis conditions, and the present invention further increases its solubility by reducing the poly-Schiff base, and at the same time has the characteristics of the original poly-S...

specific Embodiment approach 2

[0048] Embodiment 2: This embodiment is different from Embodiment 1 in that n is a positive integer ranging from 3 to 10. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0049] Specific embodiment three: the preparation method of the reduced polySchiff base of the polyaniline derivative of the present embodiment is carried out according to the following steps:

[0050] One, according to the mass volume ratio of conjugated polySchiff base and solvent is 1g: 5 ~ 30mL, the mole of C=N bond and sodium borohydride in the conjugated polySchiff base is 1: 3 ~ 10 and weighs a total of Conjugated polySchiff base, solvent and sodium borohydride;

[0051] 2. First add the conjugated polySchiff base and solvent weighed in step 1 into the three-necked flask with reflux device, then add the sodium borohydride weighed in step 1 into the three-necked flask, heat up to 10-70°C and stir Reflux for 10-72 hours, pour into methanol after cooling, filter, and vacuum-dry the obtained solid phase to obtain polyaniline derivatives.

[0052] The polyaniline derivatives prepared in this embodiment use propeller-type triarylamine as a monomer, which can effectively redu...

Abstract

The invention discloses a polyaniline derivative, a preparation method of reduced polySchiff base thereof and an application of the polyaniline derivative, which relate to a polyaniline material and a preparation method and an application thereof and are used for solving the technical problem of low dissolubility in an organic solvent and difficulty in processing into a film existing in the conventional polyaniline. The structural formula of the polyaniline derivative disclosed by the invention is shown in the specifications. The preparation method comprises the following steps of: adding conjugate polySchiff base, a solvent and sodium borohydride into a three-neck flask; raising the temperature to 10-70 DEG C, stirring and refluxing for 10-72 hours; cooling and pouring into methanol; and filtering and drying to obtain the polyaniline derivative. The polyaniline derivative is applied as a photoelectric material, and comprises an electrochromic material, a fluorescent sensing material, an acid-based sensing material, a hole transport material, a three-order nonlinear material, an anti-counterfeiting material, a camouflage material, an automobile rearview mirror material or a display material.

Description

technical field [0001] The invention relates to a polyaniline material and its preparation method and application. Background technique [0002] Entering the information age, organic electronics, as an emerging subject, has achieved rapid development. The combination of organic electronics, organic chemistry, and materials science has produced a number of new materials with excellent optoelectronic properties, covering many fields including display materials, military camouflage materials, information storage materials, sensing materials, and smart materials. Polyaniline and its derivatives with electrochromic properties have shown outstanding advantages and broad development and application prospects in the fields of display and sensing. Existing polyaniline has low solubility in organic solvents, and it is difficult to form a film by solution method, and most of the benzene rings are connected by N atoms, so the structure variety is limited and the function is single. C...
