Summary: In this study, carbon surface on cupric oxide (C@CuO) composite material was prepared using hydrothermal method with glucose as a carbon precursor. Different annealing treatments were applied to optimize the composite properties. The C@CuO-2 composite showed high crystallinity, low charge transfer resistance, and excellent oxidation activity, making it suitable for electrochemical sensing applications.

Summary: Stable and nonaromatic phenothiazinophyrins were synthesized by replacing one pyrrole ring of porphyrin with a phenothiazine unit. The synthesis was done by condensing phenothiazine-based tripyrrane with aryl aldehyde and pyrrole under acid catalysis. NMR and DFT studies revealed that the inverted pyrrole ring phenothiazinophyrins were more stable. Phenothiazinophyrins and their protonated derivatives exhibited panchromatic absorption in the visible to NIR region.

Summary: In this study, a well-defined hollow mesoporous TiN nanostructure was synthesized and utilized as a Pt catalyst support material for methanol electro-oxidation. Increasing the ammonia nitridation temperature led to higher crystallinity in the hollow TiN structure, resulting in enhanced catalytic activity of the corresponding Pt catalysts towards methanol electro-oxidation.

Summary: Four kinds of isomeric dithienoporphyrins(2.1.2.1) were synthesized using two di(1H-pyrrolo-2-yl)thiophenes as building blocks and two arylaldehydes under mild acid-catalyzed conditions. The conformation and properties of the dithienoporphyrins(2.1.2.1) were investigated using various spectroscopic techniques and theoretical calculations. The incorporation of thiophene subunits resulted in a more planarized molecular structure, and the dithienoporphyrin(2.1.2.1) acted as a ligand for metal ions, leading to bent molecular conformations.

Summary: Four isomeric dithienoporphyrins (2.1.2.1) were synthesized using two di(1H-pyrrolo-2-yl)thiophenes and two arylaldehydes under mild acid-catalyzed conditions. The dithienoporphyrins (2.1.2.1) exhibited altered molecular geometry and optical and electronic properties compared to other dibenzo-/dinaphthopor-phyrins(2.1.2.1). These dithienoporphyrins(2.1.2.1) can form metal complexes with nickel(II), copper(II), and palladium(II) ions, which exhibit bent molecular conformations and are influenced by the inserted metal ions.

Summary: A novel terpolymer containing dopamine methacrylamide (DMA) was synthesized and characterized for potential use as a biosensor coating. The presence of DMA was found to impact the properties of the copolymer, with the catechol group playing a significant role in adhesion. DMA was crucial for preventing significant desorption of the copolymer.
