Embodiment 1

[0035] This embodiment provides a polyphthalocyanine compound whose molecular structural formula is as follows:

[0036]

[0037] The polyphthalocyanine compound of this embodiment is a double-layer sandwich compound based on a planar dinuclear phthalocyanine. The preparation method of the polyphthalocyanine compound is simple, and it is suitable for application as a semiconductor material for an organic field effect transistor. After it is used in an OFET, The electron mobility of the semiconductor material layer reaches 1.0-1.5cm 2 / (V·s).

Embodiment 2

[0039] This embodiment provides a method for preparing a polyphthalocyanine compound, comprising the following preparation steps:

[0040] (1) Synthesis of 4,5-dibromo-o-xylene:

[0041]

[0042] 24 ml (0.2 mol) of o-xylene was dissolved in 30 ml of dry dichloromethane, and 2.5 g (10 mmol) of iodine and 0.6 g (10 mmol) of reduced iron powder were added to the above solution while stirring. The mixture was cooled to zero with an ice bath. In addition, 20.5ml (0.4mol) of liquid bromine was dissolved in 10ml of dry dichloromethane, and the above solution was evenly and slowly dripped into the reaction mixture within six hours with a dropping funnel, so as to invert the solution in 10% sodium hydroxide solution. The funnel absorbs the released hydrogen bromide gas. The reaction was stirred continuously at zero degrees for 38 hours and then at room temperature for 6 hours. The reaction mixture was first washed with 5% sodium hydroxide solution until colorless, and the organic...

Abstract

The invention provides a polyphthalocyanine compound, an organic field effect transistor and a preparation method of the polyphthalocyanine compound, and belongs to the technical field of synthesis of organic compounds. The invention can solve the problems that the existing polyphthalocyanine compound is very difficult to compound and separate, and very hard to apply to an OFET (organic field effect transistor). The polyphthalocyanine compound is a plane-based dicaryon phthalocyanine double-layered sandwich compound. The preparation method of the polyphthalocyanine compound is simple, and the polyphthalocyanine compound is suitable for being used as a semiconductor material of the organic field effect transistor; after the compound is applied to the OFET, the electronic mobility of a semiconductor material layer reaches .0-1.5 cm2 / (V.s).

Description

technical field [0001] The invention belongs to the technical field of organic compound synthesis, and in particular relates to a polyphthalocyanine compound, an organic field effect transistor and a preparation method thereof. Background technique [0002] Due to the diversity of its compound types, phthalocyanine has high chemical stability (it does not decompose significantly when heated at 400-500°C in air), unique optical, electrical, magnetic and other π-π interactions with its molecular macrocycle The physical properties related to the role have been widely valued by people, and they are used as semiconductor materials in the research of OFETs. [0003] The inventors have found that at least the following problems exist in the prior art: compared to monomeric phthalocyanines, due to the expansion of the conjugated system, it is difficult to synthesize and separate polyphthalocyanine compounds, and due to the limitation of synthesis technology, polyphthalocyanines Cya...
