چکیده
Polyethene with 3-thienyl functionalities pendant on short-chain branches was prepared by catalytic random copolymerisation of ethene and 3-(penten-1-yl)thiophene; the functionalities can be used to graft poly(3-hexylthiophene) onto the polyethene surface.

In the title mol-ecule, C27H25N3O3S·H2O, the dihedral angle between the planes of the thienyl ring and the pendant p-tolyl group is 39.25 (6)°, while that between the pyridine ring and the pendant phenyl ring is 44.37 (6)°. In addition, there is a slight twist in the bicyclic core, with a dihedral angle of 2.39 (4)° between the thienyl and pyridine rings. The conformation of the carbamoyl moiet...

متن کاملFunctionalizable polycyclic aromatics through oxidative cyclization of pendant thiophenes.
We present a general strategy for obtaining large sulfur-containing polycyclic aromatics from thienyl precursors through iron(III) chloride mediated oxidative cyclizations. By placing thienyl moieties in close proximity to adjacent arenes, we have directed the oxidized intermediates into controlled cyclization pathways, effectively suppressing polymer formation. Utilizing these cyclized compoun...

متن کاملDouble loading of ZnCl(2) by polytopic ligands which co-extract Zn(2+) and tetrachloridozincate.
Combining cation- and anion-binding functionalities in a salen-type extractant leads to multiple loading of ZnCl(2). Zn(ii) cations are bound by the salen N(2)O(2)(2-) donor set, and chlorozincate anions are associated with protonated pendant amine groups.
