A chiral phenylacetylene (1) having two hydroxy groups was synthesized by using an achiral catalytic system of [Rh(norbornadiene)Cl]2/triethylamine. This chiral monomer 1 was suitable to the asymmetric-induced polymerization to induce chirality in th

Since highly selective photocyclic aromatization (SCAT) of poly(substituted acetylene)s yields quantitatively the corresponding 1,3,5-trisubstituted benzene derivatives, the SCAT products were applied for quantitative determination of microstructures

In order to estimate oxygen permselectivities through a supramolecular polymer membrane for the first time , we prepared three kinds of composite membranes consisting of a supramolecular polymer membrane and a conventional organic polymer membrane. S

Chiral compounds play a vital role in our lives because we are made up of chiral polymers. A strict rule of chirality synthesis is “to obtain one enantiomer of a new chiral product, one enantiomer of a chiral source is needed”. If two enantiomers

The chain rigidity, liquid crystallinity, absorptivity, and photoluminescence of a helical poly(phenylacetylene) derivative varied significantly depending on the solvent employed, owing to the conformational changes caused by the formation or destruc

A novel phenylacetylene monomer having a perfluorinated alkyl group (M-F) was synthesized and polymerized in a chiral catalytic system to yield a one-handed helical polymer. The ability and efficiency of the chiral induction of the fluorine-containin
