Hydroquinone-pyrrole dyads with varied linkers

A series of pyrroles functionalized in the 3-position with p-dimethoxy benzene via various linkers (CH2, CH2CH2, CH=CH, C=C) has been synthesized. Their electronic properties have been deduced from 1H NMR, 13C NMR, and UV-vis spectra to detect possible interactions between the two aromatic subunits. The extent of conjugation between the subunits is largely controlled by the nature of the linker, with the largest conjugation found with the tmns-ethene linker and the weakest with the aliphatic linkers. DFT calculations revealed substantial changes in the HOMO-LUMO gap that correlated with the extent of conjugation found experimentally. The results of this work are expected to open up for use of the investigated compounds as components of redox-active materials in sustainable, organic electrical energy storage devices.

Iodine/Palladium approaches to the synthesis of polyheterocyclic compounds

Chemical Equation Represented A simple, straightforward strategy for the synthesis of polyheterocyclic compounds (PHCs) is reported, which involves iterative cycles of palladium-catalyzed Sonogashira coupling, followed by iodocyclization using I2 or ICI. A variety of heterocyclic units, including benzofurans, benzothiophenes, indoles, and isocoumarins, can be efficiently incorporated under mild reaction conditions. In addition, variations of this strategy afford a variety of linked and fused PHCs.

Rigid molecular architectures that comprise a 1,3,5-trisubstituted benzene core and three oligoaryleneethynylene arms: Light-emitting characteristics and π conjugation between the arms

In view of increasing interest in light-emitting materials, we have investigated the light-emitting characteristics and occurrence of conjugation between arms of star-shaped rigid molecules that comprise a 1,3,5-triethynylbenzene core and methoxy group-su
