The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《On bio-MOF materials doped with phosphorescent iridium complexes for molecular oxygen determination: Synthesis, characterization and performance》. Authors are Xie, Jiali; Chen, Xiang; Li, Huanrong; Chen, Zhenbo.The article about the compound:2-Phenylpyridinecas:1008-89-5,SMILESS:C1(C2=CC=CC=C2)=NC=CC=C1).Reference of 2-Phenylpyridine. Through the article, more information about this compound (cas:1008-89-5) is conveyed.
In this paper, two phosphorescent Ir(III) complexes, Ir(ppy)2(Ln), were synthesized using 2-Ph pyridine (ppy) as the first (major) ligand and two phosphorous compounds (L1 and L2) as the auxiliary ligand. Their single crystal structure and electronic structure were discussed. Ir(ppy)2(Ln) complexes were doped into a supporting matrix of bio-MOF-1 via cationic exchange to ensure their uniform distribution. Their successful doping was confirmed by SEM, fluorescence microscopy image, XRD, N2 adsorption/desorption and ICP measurement. Their photophys. parameters, including absorption spectra, excitation spectra, emission spectra, emission lifetime and quantum yield, were discussed in detail. Their phosphorescent emission was confirmed by d. functional theory and emission lifetime, making them applicable for oxygen sensing. Linear working curves were observed for both composite samples, showing sensitivity as high as 23.65 with response/recovery time of 9/22 s. Humidity effect on sensing performance was limited. These parameters were found superior to literature ones based on phosphorescent Cu(I), RE(III), Ru(II) and Re(I) complexes. The sensing mechanism was revealed as a dynamic collision between Ir(ppy)2(Ln) and O2 mols. The novelty of this work was the combination of phosphorescent Ir(III) complexes with porous bio-MOF-1, resulting in greatly improved sensitivity and linear sensing with short response time.
After consulting a lot of data, we found that this compound(1008-89-5)Reference of 2-Phenylpyridine can be used in many types of reactions. And in most cases, this compound has more advantages.
