So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Ai, Yong; Wu, Dong-Ji; Yang, Meng-Juan; Wang, Pan; He, Wen-Hui; Liao, Wei-Qiang researched the compound: (R)-(-)-3-Fluoropyrrolidine Hydrochloride( cas:136725-55-8 ).Electric Literature of C4H9ClFN.They published the article 《Highest-Tc organic enantiomeric ferroelectrics obtained by F/H substitution》 about this compound( cas:136725-55-8 ) in Chemical Communications (Cambridge, United Kingdom). Keywords: organic enantiomeric ferroelec substitution phase transition temperature. We’ll tell you more about this compound (cas:136725-55-8).
Through the strategy of F/H substitution, we precisely designed the highest-Tc (phase transition temperature) organic enantiomeric ferroelecs., (R)- and (S)-(N,N-dimethyl-3-fluoropyrrolidinium) iodide, of which the Tc reaches up to 470 K, far beyond those of other enantiomeric ferroelecs. and also the com. ferroelec. BaTiO3.
This literature about this compound(136725-55-8)Electric Literature of C4H9ClFNhas given us a lot of inspiration, and I hope that the research on this compound((R)-(-)-3-Fluoropyrrolidine Hydrochloride) can be further advanced. Maybe we can get more compounds in a similar way.
