Norbornene-based polymerized ionic liquids (PILs) were systematically prepared to understand the role of PIL architecture and linker on the ionic conductivity (σDC), segmental dynamics, and dielectric constant. In PILs with two- or one-armed imidazo

Ion transport and segmental dynamics were studied for one- and two-armed norbornene ionic liquid monomers (ILMs) including imidazolium (Im+)-bis(trifluoromethanesulfonyl)imide (Tf2N–) pairs, with d...

Reaction of isoquinoline Reissert compound 1 with NaH and then isopropyl iodide in DMF at 22 °C led to four isolated products. Ketone 3 is the expected product of the well-known rearrangement of the intermediate Reissert anion. Cyano lactam 4 result

The two isomers 6 and 9 of cis(4,4′-)-dicarbomethoxydibenzo-27-crown-9 with tri- and tetra-(ethyleneoxy) linkages transposed were synthesized regiospecifically in high yields (94 and 92%, respectively) by the Wang–Pederson–Wessels (WPW) protoco

The first dual component pseudocryptand-type [2]pseudorotaxanes were designed and prepared via the self-assembly of synthetically easily accessible bis(meta-phenylene)-32-crown-10 pyridyl, quinolyl, and naphthyridyl derivatives with paraquat. The for

1,2-Bis[N-(N′-alkylimidazolium)ethane salts form complexes presumed to be pseudorotaxanes with crown ether and cryptand hosts. The association constants of 1,2-bis[N-(N′-butylimidazolium)]ethane bis(hexafluorophosphate) with dibenzo-24-crown-8 an

New polymers that incorporate paraquat or crown ether moieties as chain ends or central units were synthesized by stable free radical polymerization (SFRP) and atom transfer radical polymerization (ATRP). For SFRP, TEMPO derivatives that contain a fu
