In an article, published in an article, once mentioned the application of 17261-28-8, Name is 2-(Diphenylphosphino)benzoic acid,molecular formula is C19H15O2P, is a conventional compound. this article was the specific content is as follows.HPLC of Formula: C19H15O2P
The present invention has offered a kind of two-photon and near-infrared light emitting characteristics of a nitrosyl hydrogen fluorescent probe and its preparation method and application, relates to the field of biological chemical material. The present invention provides a fluorescent probe nitrosyl hydrogen of the structure shown in formula I, the nitrosyl hydrogen fluorescent probe has a two-photon absorption and near-infrared emission characteristic, nitrosyl hydrogen can be applied to detection in the cell, and the cell and can prolong the excitation wavelength in the tissue of the nitrosyl hydrogen (920 nm) and emission wavelength (700 nm), reduce the light cell and tissue damage, increase tissue penetration depth and imaging depth, reducing the biological background fluorescence interference, to obtain higher imaging resolution; at the same time, the present invention provides a fluorescent probe of the nitrosyl hydrogen can rapidly detect nitrosyl hydrogen, in the 37 C lower short response time, is not sensitive to pH, the nitrosyl hydrogen cell in imaging with specificity, can be in two-photon excitation under the conditions of the nitrosyl hydrogen detection in living cells.
