Wu, Wen Xin; Liu, Hu Cheng; Jin, Wei Jun published the artcile< Halogen Bonding Adsorbent Pyridine N-oxides for Iodine Capture in Water>, Recommanded Product: 2-Mercaptopyridinen-oxide sodiumsalt, the main research area is anthracene naphthaline pyridine oxide adsorbent single crystal surface structure; SC-SC transformation; halogen bonds; iodine capture; nonporous materials; pyridine N-oxide.
Rapid capture of 129I with high volatility and toxicity in the environment has attracted much attention. Herein we reported a firstly synthesized nonporous material: pyridine N-oxides (NTPO and ATPO) as iodine adsorbent. Both of NTPO and ATPO exhibit remarkable performance on the adsorption of iodine in aqueous solution, vapor state and organic solvents. Upon the capture of iodine, pyridine N-oxides were transformed to binary cocrystals combined with the pyridine N-oxides and iodine which is driven by halogen bond between iodine and oxygen atoms. Moreover, pyridine N-oxides shows high chem., thermal and moisture stability.
