Abstract

The invention provides a perylene bay 1,7-bit nitro-containing perylene bisimide derivative. The perylene bay 1,7-bit nitro-containing perylene bisimide derivative is used for preparing a perylene bay 1,7-bit nitro-containing perylene bisimide derivative microwire, and is used for preparing a gas-sensitive element of a resistor-type gas-sensitive sensor; in the prepared gas-sensitive element, a material forming a source zone and a drain zone is simple substance gold, the material for forming a channel region is the perylene bay 1,7-bit nitro-containing perylene bisimide derivative microwire, and the material for forming a gate medium layer is silicon and silica. The gas-sensitive element used in the ammonia gas detection has the advantages that the response and recovery time is short, the detection limit is low, the resistor-type gas-sensitive sensor is simplified and minimized, the carrying is facilitated, and the effective and rapid detection of ammonia gas is achieved.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a perylene imide derivative containing a nitro group at the 1,7-position of perylene and its application in ammonia gas detection. Background technique [0002] In recent years, with the continuous development of industrial production and the improvement of people's living standards, environmental problems have become increasingly prominent. Combustible gas combustion and toxic gas leakage incidents have been reported from time to time, and environmental quality and public ammonia health issues have attracted widespread attention from the society. In view of this, the development and development of gas sensors with excellent performance has become the primary task of relevant researchers. Especially in recent years, the continuous development and progress of nanomaterials and technologies have greatly promoted the preparation and application of new gas sens...
