At present, the practical quantum infrared detectors are mainly inorganic materials based on mercury cadmium telluride. The problems of these materials are: high preparation cost, complicated process, and cannot be prepared on cheap substrates, especially silicon substrates and metal electrodes. , thus limiting the application of infrared detectors with important military applications

[0005] So far, the basic and applied research on organic semiconductor materials and devices has mainly focused on organic light-emitting displays and organic photovoltaic solar cells. There are few research reports on organic infrared semiconductor materials and devices. At present, there are few types of organic infrared semiconductors that can be applied to detection less on the

Moreover, due to the van der Waals force between organic semiconductor molecules, the carrier mobility is low, the resistivity of photosensitive materials is large, and the properties are close to insulators, these factors limit the application of organic infrared semiconductors in the field of infrared detection.
