Highly efficient self-powered perovskite photodiode with an electron-blocking hole-transport NiO layer.

Hybrid organic-inorganic perovskite materials provide noteworthy compact systems that could offer ground-breaking architectures for dynamic operations and advanced engineering in high-performance energy-harvesting optoelectronic devices. Here, we demonstrate a highly effective self-powered perovskite-based photodiode with an electron-blocking hole-transport layer (NiO). A high value of responsivity (R = 360 mA W) with good detectivity (D = 2.

Cobalt(II)-coordination polymers containing glutarates and bipyridyl ligands and their antifungal potential.

Three new Co-coordination polymers (Co-CPs) containing glutarates and bipyridyl ligands, formulated as [Co(Glu)(µ-bpa)]·(HO) (1), [Co(Glu)(µ-bpp)] (2), and [Co(Glu)(µ-bpe)]·(HO) (3), were prepared, and their structures were determined by X-ray crystallography. Glutarates bridge Co ions to form 2D sheets, and the sheets are connected either by bpa or by bpp ligands to form 3D networks 1 and 2, respectively. Both frameworks 1 and 2 are two-fold interpenetrated, and there is no significant void volume in either network.
