      The cover picture shows the concept underlying the design of a melanin-inspired electroluminescent material for organic light-emitting diode devices. Both symmetric and asymmetric triazatruxene derivatives were synthesized. Comparison of the opto-electronic properties of these derivatives, supported also by theoretical calculations, suggests that the asymmetric isomers are more promising for application in organic electronics.

The material with 40 mol % AgBr displayed a regular necklace-like morphology and samples with 10 to 50 mol % AgBr exhibited enhanced plasmonic photocatalytic performance for the degradation of organic pollutants (methyl orange, methylene blue, and rhodamine B) under visible light.

      Avoiding over-reaction: Various dideuterochalcones have been synthesized selectively by means of the highly controlled partial deuteration of antidiabetic chalcone derivatives. The benefits of continuous-flow processing were exploited in combination with on-demand electrolytic generation of D2 gas (see figure) to avoid over-reaction to undesired side products and to achieve selective deuterium incorporation without the need for special reagents.

      A low-cost and facile method was used to synthesize bipyramidal single-crystals of TiO2 having a high percentage of (101) facets, which were further attached along the [001] direction to form connected nanorods. These single crystals showed enhanced long-range atomic arrangement with significantly improved energy conversion efficiency owing to its superior charge transport ability and high surface area (see figure).

      Tuning bands: The positions of the conduction and valence bands of CdS nanorods can be manipulated by Au3+ doping (see picture) The physicochemical properties in the series AuxCd1−xS (x=0 to 0.1) could be modified as a result of surface-structural distortion. The ease of charge separation and facile transfer to the reactant species results in long-term activity and stability under sunlight irradiation.

Photophysical investigation by time-resolved transient absorption, mainly fluorescence and femtosecond spectroscopy, evidences efficient intermolecular energy transfer from the photoexcited central porphyrin to the peripheral phthalocyanines in the ensembles (see picture).

      Put a coat on! Modifying TiO2 with carbon nanolayers increases substrate adsorption in the vicinity of the photocatalytic sites. That, along with the high migration efficiency of photoinduced electrons at the carbon/TiO2 interface, leads to a photocatalyst with enhanced efficiency (see figure).
