Embodiment 1

[0028] Preparation of compound 1:

[0029] The ligand 2-quinoline formaldehyde (47mg, 0.3mmol), 2-aminoquinoline (43mg, 0.3mmol) and Mn(CO) 5 Br (82mg, 0.3mmol) was placed in methanol (5mL) and heated to reflux, and the reaction bottle was wrapped with tinfoil to avoid light, and the mixed solution was refluxed for four hours, cooled, and finally filtered with suction to obtain the Schiff base-based Ligands of Manganese Carbonyl Compounds 1. 1 H NMR (400MHz, DMSO) δ9.69(s, 1H), 8.91(d, J=8.5Hz, 2H), 8.74(d, J=9.0Hz, 1H), 8.44 (d, J=8.0Hz, 1H ), 8.29(d, J=8.7Hz, 1H), 8.15(dd, J=17.8, 9.3Hz, 3H), 8.00–7.86(m, 3H), 7.73(t, J=7.7Hz, 1H)( figure 1 ).

Abstract

The invention discloses a light-induced manganese carbonyl compound carbon monoxide releasing agent which has a structure as shown in a formula (1). Quinoline formaldehyde and an aminoquinoline ligand with a relatively large conjugated system are selected to react with pentacarbonyl manganese bromide to obtain a corresponding manganese carbonyl compound; the compound can be decomposed to release carbon monoxide under the action of visible light, and the defect that a manganese carbonyl compound is induced to generate carbon monoxide under the action of ultraviolet light is overcome.

Description

technical field [0001] The invention relates to the field of light-induced manganese carbonyl compound carbon monoxide release agent. More specifically, the present invention relates to a light-induced manganese carbonyl compound carbon monoxide release agent and its preparation method and application. Background technique [0002] Carbon monoxide (CO) is a deadly toxic gas, but in 1991, Mark et al. found that it has important physiological functions in organisms. It is the second gas messenger molecule discovered after NO, and it is also a neurotransmitter. Studies have found that carbon monoxide, as a cell messenger molecule, can play an important regulatory role in organisms. However, CO, as a toxic gas, will cause harm to the human body in excess. In order to utilize CO safely and effectively, the concept of carbon monoxide releasing agents (CORMs) has been proposed, that is, to achieve fixed-point and quantitative release of CO under specific conditions through CO car...
