Abstract

The invention discloses the preparation and application of a fluorescent compound with sensing function for arylamine lung cancer markers and a fluorescent sensing film thereof, belonging to the technical field of fluorescent compound preparation. The fluorescent compound contains cholesterol fragments and perylene anhydride units. The cholesterol fragment has the advantages of rigid skeleton, multi-chiral center and strong van der Waals interaction. The perylene anhydride has high fluorescence quantum yield, good photochemical stability and strong π‑ π-stacking, these building blocks make the prepared fluorescent compounds possess supramolecular properties and extremely rich assembly behaviors at the same time. The microscopic appearance of the sensing thin film prepared by the invention is controllable, has good photochemical stability, high sensitivity and can be used repeatedly. It is of great significance to realize the early diagnosis of lung cancer patients.

Description

technical field [0001] The invention belongs to the technical field of preparation of fluorescent compounds and the preparation of sensing thin films, and specifically relates to the preparation and application of fluorescent compounds capable of sensing aromatic amine lung cancer markers such as aniline and o-toluidine, and fluorescent sensing thin films. Background technique [0002] Lung cancer is a common cancer with a high mortality rate. Studies have found that its early diagnosis is extremely critical for the treatment of lung cancer. However, the existing technology is not enough, and its early diagnosis can only rely on regular health checks. In the study, it was found that the breath of lung cancer patients, including early-stage patients, often contains higher levels of aromatic amine gases such as aniline and o-toluidine than healthy people. These two types of aromatic amine gases are also recognized markers of lung cancer. In addition, aromatic amine organic am...
