Abstract

The invention belongs to the field of chemical synthesis, and discloses a photochromic perfluoro cyclopentene molecular fluorescent probe compound and a preparation method thereof. The photochromic perfluoro cyclopentene molecular fluorescent probe compound can be used for realizing molecular recognition through a specific receptor binding object, realizing in-situ real-time detection on the single-molecular level due to high selectivity and sensitivity, performing remote detection due to utilization of optical fiber, and realizing visualization of detection results through variation of output signals such as ultraviolet absorption and fluorescence. The photochromic perfluoro cyclopentene molecular fluorescent probe compound can be used for preparation of a multiple regulation photoswitch and a photochromic light-emitting device based on the fluorescence switch property of the photochromic perfluoro cyclopentene molecular fluorescent probe compound, and design of a novel logic gate and the like based on the fluorescence multiple regulation characteristic.

Description

technical field [0001] The invention belongs to the field of organic photochromic materials, in particular to a synthesis method and application of a novel photochromic perfluorocyclopentene molecular fluorescent probe compound containing salicylaldehyde Schiff base. Background technique [0002] With the rapid development of social economy, more and more problems have been highlighted, especially environmental pollution, food safety, etc. Among them, metal ions, especially toxic metal ions, have attracted widespread attention and concern because of their toxicity. Therefore, rapid and accurate detection of metal ions is particularly important. Developing efficient sensors is one of the important strategies to solve such problems. The various analytical methods currently used to detect heavy metal ions are expensive, usually require a relatively large sample size and cannot be continuously detected. Fluorescent molecular probes are a new method emerging in the field of mol...
