Technical Field

The invention belongs to the technical field of organic synthesis, and particularly relates to an organic photoelectric semiconductor material, and a synthesis method and application thereof.

Background

Organic semiconductor devices such as organic solar cells (OPVs), Organic Light Emitting Diodes (OLEDs), Organic Electrochromism (OECs), and Organic Thin Film Transistors (OTFTs) have been developed and applied in many fields. In all these organic photoelectric fields, organic photoelectric materials are key. The organic semiconductor material which is designed and synthesized and has simple process, lower cost, stable material performance and long service life so as to achieve the purpose of commercialization has wide application prospect.

The condensed ring acene material is an organic material with good photoelectric property. For example, the single crystal mobility of pentacene has reached 15-40cm²V^-1s^-1. Anthracene is the smallest member of the acene family with transistor properties and has better luminescence and device performance. In general, increasing conjugation can increase the combination of transfer integration and decreasing recombination energy resulting in higher charge carrier mobility. Therefore, naphthalene ring is added in the middle of the anthracene ring, so that conjugation is increased, and luminescence of anthracene is maintained.

Although a large number of organic semiconductor materials have been designed and synthesized, there are not many materials that have high fluorescence quantum efficiency and high mobility. However, such materials are critical in the preparation of OLETs and OLEDs. The preparation of such materials is of great importance.
