Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.1835-49-0, formula is C8F4N2, Name is Tetrafluoroterephthalonitrile. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Synthetic Route of 1835-49-0.
Guo, Yu;Zhang, Lingling;You, Hongjun;Fang, Jixiang research published 《 A solution-based SERS sensing protocol via the ultra-rapid and highly efficient molecule enrichment strategy》, the research content is summarized as follows. The solution-based SERS detection has been considered as one of the most mature com. SERS detection protocols owing to its features of high sensitivity and timeliness. However, poor mol. generality is a challenge for weakly-adsorbed species, such as anionic mols. and complicated organic compositions, on the surfaces of the plasmonic nanostructures. Many mols. in solution especially the weakly-adsorbed organic pollutants cannot be effectively adsorbed onto the surface of metal nanoparticles quickly due to the low affinities towards the metal, hence showing the weak Raman activity. Herein, we report a solution-based SERS sensing protocol via the highly efficient mol. enrichment strategy to achieve highly sensitive detection in solution With the help of pH adjustment in solution, the porous β-cyclodextrin polymer/magnetic nanoparticles (PCDPMNs) can availably capture various types of mols., including cationic dyes (e.g., methylene blue and crystal violet), anionic pigment (e.g., sunset yellow), and neutral organic pollutants (e.g., carbendazim and bisphenol A). Based on the mol. enrichment strategy, the enrichment factors of various mols. are up to 102-103, thus their Raman signals are enhanced by 2-3 orders of magnitude. The mol. enrichment strategy provides a new way for the practical SERS detection to improve the ultra-trace detection in solution
