Abstract: New H-bonded supramolecular assembliesare obtained using the polyfluorobiphenyl H-donor derivatives and 18-crown-6 ether. Cocrystals of octafluorobenzidine with 18-crown-6 of 1:1 stoichiometry belong to the enantiomorphous space groups P65 and P61. The helical self-assembly of these… read more here.

Abstract: The helical insertion behavior of block poly(p-phenylene)-polyacetylene (PP-PA) copolymer into single-walled carbon nanotube (SWCNT) is researched by molecular dynamics simulations. When blocking, PP chain can induce the stiff PA chain into helix. The contributions of… read more here.
