Paragraph 0043; 0047; 0048; 0050; 0055-0057; 0058, (2019/11/28)
The invention belongs to the technical field of biological fluorescence analysis, and particularly relates to a 3-hydroxy flavone compound and an application thereof. The compound is particularly a 4-n,n-dialkylamino-3-hydroxy flavone compound, and when the compound is used as a fluorescent dye, the lipid droplet targeting property is better, and a cytoskeleton is hardly colored. When conjugated structures such as a benzene ring and the like are added to the left side of a molecule of the compound, the emission wavelength of the molecule can be greatly prolonged, and fluorescence crossing of the molecule from yellow to red is realized. The compound can be applied to the aspects of dynamic lipid droplet imaging in cells, lipid droplet growth process imaging, adipose tissue imaging, even simultaneous imaging of intramuscular fat and intermuscular fat in skeletal muscle tissues, and the like, and has important application values in the fields of fluorescent dyes, biological fluorescent labels and the like.

A new series of monosubstituted styryl- and bistyryl-2,2′-bipyridine luminophores (compounds 16-23) have been synthesized via Horner-Wadsworth-Emmons reaction involving a monophosphonate and donor aromatic aldehydes. In the title chromophores, the amino donors are varied between acyclic and cyclic while the alkoxy donors are varied in terms of their number and position. The absorption maxima of these chromophores shift predominantly due to intramolecular charge transfer (ICT) between different donor and acceptor moieties. The title donor-acceptor molecules exhibit intense fluorescence in solution at room temperature, and their emissive behavior has been found to be highly sensitive to solvent polarity. The fluorescence spectra and quantum yields of all the chromophores were recorded in four different solvent media, and the chromophores 16, 17, 19, and 21 exhibit fluorescence in the solid state too. The influence of the nature and position of the donor functionalities in the conjugated backbone of the bipyridine moiety on the electronic absorption properties of the title chromophores (16-23) has been demonstrated, which has further been corroborated by DFT and TD-DFT computation both in gas phase and in solution phase. The crystal structure of compound 18 has been described as a representative member of the family (16-23).
