Synthesis of oligo(thiophene)-coated star-shaped ROMP polymers: Unique emission properties by the precise integration of functionality

A facile synthesis of oligo(thiophene)-modified (coated) soluble star (ball)-shaped polymers has been achieved via sequential living ring-opening metathesis polymerization (ROMP) of norbornene and a cross-linking reagent using Mo(CHCMe2Ph)(N-2,6-iPr 2C6H3)(OtBu)2 as the initiator and oligo(thiophene) carboxaldehydes for termination. The resultant star-shaped ROMP polymers containing ter- and tetrathiophene moieties exhibit unique emission properties due to an integration of the ROMP polymers (arranged functionalities): the blue emission was tuned to the white emission upon addition of 2-[2-[(E)-4-(dimethylamino)styryl]-6-methyl-4H-pyran-4-ylidene] malononitrile.

Synthesis of Thiophene/phenylene Co-oligomers. IV [1]. 6- to 8-Ring Molecules

We report the synthesis of various thiophene/phenylene co-oligomers with total number of thiophene and benzene (phenylene) rings of 6 to 8. These compounds include a phenyl-capped sexithiophene, a thienyl-capped quaterphenylene, as well as block and alternating co-oligomers. The synthesis is based on either the Suzuki coupling reaction or the direct dimerization coupling. The latter method produces symmetric molecules with an even total ring number. These reaction schemes enables us to obtain the target compounds in high quality. Although the resulting materials are difficult to dissolve in organic solvents and therefore difficult to identify by usual 1H nmr spectroscopy, they have successfully been identified through Fourier-transform ir spectroscopy. The specific group frequencies of ring-stretching and out-of plane deformation modes are characteristic of the substitution pattern of the individual thiophene and benzene rings.
