Abstract

The invention provides a gold(III) complex-perylene diimide derivative and a fluorescence sensing tube and tube-type fluorescence sensor prepared therefrom. The alkyne-based (III) structure is introduced into the perylene diimide anhydride site modified by the curved position, and the non-planarity of the formed structure effectively suppresses the strong intermolecular stacking effect of the perylene diimide and avoids aggregation-induced fluorescence quenching. The cyclometalated Au(III) complex and the perylene diimide can also form an ideal energy donor-acceptor pair, thereby effectively broadening the surface of the system. The Stokes displacement is observed, which lays the foundation for the structural optimization of the sensor to be built. The gold(III) complex-perylene diimide derivative has good fluorescence properties, and the tubular fluorescence sensor has high sensitivity.

Description

technical field

[0001] The invention belongs to the technical field of small molecule fluorescent sensing materials, in particular to a gold (III) complex-perylene diimide derivative and a fluorescent sensing tube and a tube-type fluorescent sensor prepared therefrom. Background technique

[0002] The diverse needs of residents for interior decoration have led to more and more furniture that only pays attention to aesthetics and does not pay attention to environmental protection and health. The increasingly serious indoor air pollution will not only cause environmental pollution, but also threaten human health. As the source of disease, formaldehyde is the number one invisible killer indoors that endangers public health, and it is also one of the indicators of public health standards in my country. Formaldehyde, also known as formaldehyde, is a colorless gas, but it has a certain pungent odor and can enter the human body through the respiratory tract. Because formaldehyde h...
