A phenyl ethanediol derivative having a polymerizable group at least one, the present invention is that it further comprises a photo-convertible group at least one for adjusting the helical twisting power of the phenyl ethanediol derivative on the phenyl ethanediol derivative characterized. In a ...
The syn-oriented 2-OH provides a favorable proton transfer geometry in 1,2-diol monoester aminolysis: implications for the ribosome mechanism. A computational study of 1-formyl 1,2-ethanediol aminolysis predicts a stepwise mechanism involving syn-2-OH-assisted proton transfer. The syn-oriented 2-...
Generalized gradient approximation density functional theory calculations at BP, B3P, BLYP and B3LYP levels coupled with a series of basis sets of increasing quality are presented for the six gauche conformers of 1,2-ethanediol. The results show that the extent of the correlation effects depends ...
sulfonate group, amino group, hydroxyl group or polyoxyethylene group) as an essential component in the presence of a mercaptan-based chain transfer agent (e.g. 1-mercapto-1,1-methanediol) having >=2 hydroxyl groups and one mercapto group as a polyol component with (B) a polyisocyanate (e...

A multi-arm tree fork type polyethanediol with active terminal group is disclosed, and can be used to modify the low-molecular medicines, and protein or polypeptide medicines for improving their solubility, stability and immunogenicity, resulting in elongated half life period and raised curative ...
When DEG was replaced by 1,2-ethanediol, the product can also be indexed as pure-phase cubic NaYF4 crystal (Figure 2b). All of these results indicated that IL BmimPF6 in the presence of polyol also acts as a crystal-phase manipulator during the formation of NaYF4 [18]. NNaannoo...
