Problems solved by technology

Although the research on gas sensor of perylene imide derivatives has made great progress in recent years, its performance research still has the following deficiencies: 1) The current research work is mainly focused on the fluorescent gas sensor that depends on its optical property change, while The research on resistive gas sensor based on its semiconductor properties is relatively lagging behind, which is not conducive to its miniaturization development, and is not conducive to efficient and fast gas detection; 2) The gas sensitivity is low, which limits its application in real life; 3) The molecular design of perylene imide derivatives used in the study of gas sensors is not systematic, and the relationship between molecular structures and their sensing properties has not been elucidated

Abstract

The invention discloses a perylene bisimide derivative containing beta-pyranoside. The structural formula is shown in the specification. The perylene bisimide derivative containing beta-pyranoside is used for preparing a detection electrode of a gas sensitive sensor, when the detection electrode is placed in 5 ppm hydrazine hydrate gas, electron transfer occurs between gas molecules and the perylene bisimide derivative, as a result, the current of the gas sensitive sensor has 5 orders of magnitude of change within 2-3 s, and efficient detection for specific gas is realized.
