Abstract

The invention discloses a carbon monoxide detecting fluorescent probe and a preparation method and application thereof. The carbon monoxide detecting fluorescent probe has a molecular formula of C44H40N4O8Pd2 and a following structure of A. The carbon monoxide detecting fluorescent probe is weak in fluorescence and is blue when dissolved in water or organic solvent; under action of carbon monoxide, the solution of the carbon monoxide detecting fluorescent probe turns light in color and gradually increases fluorescence of 657 nm. The carbon monoxide detecting fluorescent probe is high in selectivity and identifiability of carbon monoxide detection as well as detecting sensitivity, clear in phenomenon and convenient to identify. The preparation method of the carbon monoxide detecting fluorescent probe is simple, and the prepared carbon monoxide detecting fluorescent probe is high in product yield.

Description

technical field [0001] The invention relates to a fluorescent probe for detecting carbon monoxide, a preparation method and application thereof, and belongs to the field of small organic molecule fluorescent probes. Background technique [0002] Carbon monoxide (CO) is not only a major air pollutant, but also closely related to animal and human health. Carbon monoxide exists mainly in the form of carbon monoxide in living organisms. A small amount of carbon monoxide in the air can promote the opening of the stomata of plant leaves and thus increase the photosynthesis rate of plants. Studies have shown that the concentration of carbon monoxide in the air is too high, which will significantly affect the growth of plants and even reduce crop yields. Although studies have shown that carbon monoxide can stimulate the excitability of the nervous system, it can cause respiratory diseases at high concentrations. A certain amount of carbon monoxide can cause allergies or asthma in...
