Textile‐surface interfacial asymmetric polymerization

Abstract

This research demonstrated that polymerization of aniline on cellulose produces chiroptically active composites. Polymerization of aniline in the presence of cotton fibers consisting of chiral cellulose are performed to prepare a polyaniline (PANI)/cotton composite. The polymerization is conducted at the cotton interface. The resultant PANI/cotton composite shows chiroptical activity elucidated with diffuse reflectance circular dichroism. In this reaction, textile‐surface interfacial asymmetric polymerization is performed with imprinting of chiral structure from the cotton as a natural chiroptically active polymer to the PANI. © 2014 Wiley Periodicals, Inc.

Synthesis and characterization of Polyaniline composite with Shell membrane

“…Aniline sulfonic salt can be absorbed into the shell membrane by capillary effect [28]. The aniline molecules are arranged along the membrane prior to polymerization because of the intermolecular hydrogen bonding, or electrostatic interaction between aniline molecules and the protein of the shell membrane [13].…”

Nanocellulose enriches enantiomers in asymmetric aldol reactions

“…21 Although the reaction selectivities were insufficient from the viewpoint of asymmetric synthesis, these two reports clearly indicated that nanocellulose has the potential to induce enantioselectivity, possibly owing to its inherent chiral nanoarchitecture. [22][23][24][25] As tremendous research effort has been focused on developing enantioselective catalysis, enantiodiscrimination based on naturally-occurring and renewable nanocellulose would be a promising development for a greener ne chemical industry. Herein, we report for the rst time that nanocellulose signicantly enhanced enantioselectivity and catalytic efficiency in proline-catalyzed aldol reactions, as shown in Fig.…”
