A series of ladder-type graphene ribbon oligomers have been synthesized through DDQ/acid-mediated oxidative cyclization. The oligomers present a bright blue light emission, and the new oligomers were clearly characterized by NMR and MALDI-TOF.

Panchromatic RuII sensitizers TF-30-TF-33 bearing a new class of 6-quinolin-8-yl-2,2′-bipyridine anchor were synthesized and tested under AM1.5 G simulated solar irradiation. Their increased π conjugation relative to that of the traditional 2,2

5,6-Disubstituted phenanthridinium cations have a range of redox, fluorescence and biological properties. Some properties rely on phenanthridiniums intercalating into DNA, but the use of these cations as exomarkers for the reactive oxygen species (ROS), superoxide, and as inhibitors of acetylcholine esterase (AChE) do not require intercalation. A versatile modular synthesis of 5,6-disubstituted phenanthridiniums that introduces diversity by Suzuki-Miyaura coupling, imine formation and microwave-assisted cyclisation is presented. Computational modelling at the density functional theory (DFT) level reveals that the novel displacement of the aryl halide by an acyclic N-alkylimine proceeds by an SNAr mechanism rather than electrocyclisation. It is found that the displacement of halide is concerted and there is no stable Meisenheimer intermediate, provided the calculations consistently use a polarisable solvent model and a diffuse basis set.

A large variety of halogenated nitroarenes have been selectively reduced with hydrazine hydrate in the presence of Pd/C to give the corresponding (halogenated) anilines in good yield.

(Graph Presented) A new class of polycyclic aromatic hydrocarbons - oligoindenopyrenes - has been synthesized featuring a Pd-catalyzed Suzuki - Heck coupling cascade. The oligoindenopyrenes are robust, highly colored substructures of C70 and have properties that might prove useful in new organic materials or devices. After excitation, the tetraindenopyrene derivative 3d undergoes efficient deactivation (99%) by internal conversion to the ground state. The small fluorescence quantum yield (0.004) is in accordance with the short (0.6 ns) fluorescence decay time.
