Abstract

A thermochromic organic field effect transistor comprises an organic semiconductor layer, the organic semiconductor layer contains a spiropyrane structure compound, the spiropyrane structure compound is introduced into the organic field effect transistor as a thermochromic material, and under the heating or cooling condition, the molecular structure of the spiropyrane structure compound is changed, so that the thermochromic organic field effect transistor is obtained. Meanwhile, due to the fact that the structure of the transistor is changed, the mobility of the transistor is changed accordingly, and then the performance of the transistor is also changed accordingly.

Description

technical field [0001] The invention relates to the technical field of organic field effect transistors, in particular to a thermochromic organic field effect transistor. Background technique [0002] Organic field-effect transistors (OTFTs) have great advantages over silicon-based transistors in terms of manufacturing cost, preparation adjustment, etc. For example, organic field-effect transistors can be used to prepare flexible devices, and large-area devices can be prepared by solution methods, making them have broad industrial applications. prospect. With the deepening of research on flexible OTFTs, organic field effect transistors have attracted more and more attention in various fields, such as pressure sensing, biosensing, detectors, etc. Among them, organic thermochromic materials have reversible photo-induced structural changes, which can be used in devices to make the devices have photo-responsive properties.
