The article conveys some information:
We have synthesized and characterized an acceptor-π-donor-π-acceptor type pyridinium salt. The salt exhibited yellow emission with large Stokes shift in solution and was successfully excited by NIR irradiation via two-photon absorption process. In addition, it was found that the usage of the salt as a bioimaging agent for HeLa cells visualizes cell death. The combined use of the salt and a com. available green fluorescent dye for the detection of live cell viability realized the one-shot fluorescence imaging of live and dead HeLa cells under the single blue excitation. In the experiment, the researchers used many compounds, for example, 4-Ethynylpyridine(cas: 2510-22-7Application of 2510-22-7)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Application of 2510-22-7
