Novel chromophores from alternated pyridine–ethylenedioxythiophene unit oligomers: dramatic enhancement of photoluminescence properties in elongated derivatives
Mixed-Ligand Approach to Palladium-Catalyzed Direct Arylation of Heteroarenes with Aryl Chlorides: Controlling Reactivity of Catalytic Intermediates via Dynamic Ligand Exchange
catalyst facilitates directarylation with readily available but less reactive aryl chloride, yielding the coupling products in high yield (up to >99%). Moreover, the catalyst enables sequential reactions that leverage the differential reactivity between C–Cl and C–Br bonds, producing π-extended small molecules in a one-potsynthesis. The catalyst also proves effective in directarylation polymerization
Novel chromophores from alternated pyridine–ethylenedioxythiophene unit oligomers: dramatic enhancement of photoluminescence properties in elongated derivatives
Novel chromophores based on the alternation of electron-poor (pyridyl) and electron-rich (ethylenedioxythienyl) heterocycles were synthesized for the first time and shown to exhibit attractive optical properties in relation with their specific electronic and geometrical (coiled structure) features.
