Bioreducible FA-PEG-<italic>b</italic>-P(α-Pt(<sc>ii</sc>)-SS-CL/CL) conjugates have been successfully developed in order to build redox-responsive micelles with targeting and site-specific drug releasing abilities.

Controlling the phenomenological morphology effects on performance of perovskite solar cell (PSC) is a continuing concern due to its photo-physical complexity and existing contrary reports. Distinguishing effect formed electron hole traps in bulk at surface/interfaces layer from their impact device can be beneficial optimizing fabrication methods. Here, transient AC steady state DC measurements, characterizations confirm variation parameters with respect grain boundaries growth. The physics...

In the present work, Cu/perovskite-type structures of general formula Cu/Ca(ZrxTi1-x)O3 (x = 1, 0.8, 0.6) were synthesized via sol-gel process and afterwards using wetness impregnation method to prepare copper-based catalysts. The physicochemical properties prepared catalysts studied XRD, SEM, NH3-TPD, H2-TPR TGA analyses. Structural measured through Brunauer-Emmett-Teller analysis (BET). These catalytic systems also found be highly active, selective sustainable. this regard, methanol...

The self-assembly of a new flexible tritopic pyrazine−pyridine ligand (pz-3-py) with HgX2 (X = Cl, Br) was investigated. results show that coordinated chloride and bromide anions play different roles, two architecturally coordination polymers were obtained the used. Where X in [Hg(μ3-pz-3-py)Cl2]n (1), 2D network is isolated, while for Br, [Hg(μ-pz-3-py)Br2]n (2), 1D zigzag chain constructed. Our noncovalent interactions such as hydrogen bond, halogen···halogen, halogen···π interactions,...

In this work, a new aerobic route is introduced for the selective oxidation of variety aromatic and aliphatic alcohols to corresponding aldehyde ketone derivatives by molecular oxygen in presence free base porphyrins metalloporphyrins as sensitizers using white light or sunlight an organic solvent. The method shows wide scope, exhibits chemoselectivity proceeds under mild reaction conditions. resulting products are obtained good conversions reasonable time.

The self-assembly of an exoditopic N-donor ligand (3-py-3-py) with HgX2 (X = Cl, Br, I) was investigated. X-ray structure analysis shows that all the compounds have infinite one-dimensional and Hg(II) ions are in a distorted trigonal pyramidal N2HgX2 geometry. Our results indicate coordinated anion can control structural motif resulting coordination polymers through cooperative weak noncovalent interactions. In case [Hg2(μ-3-py-3-py)2Cl4]n (1) [Hg2(μ-3-py-3-py)2Br4]n (2), 1D zigzag chains...

Over the past decade, tremendous effort has been made to improve light-harvesting ability of push–pull porphyrin dyes. Despite notable success achieved in this direction, dyes still suffer from a poor efficiency owing lack absorption between Soret and Q-bands. To tackle issue, here we design series with anchoring groups either at meso- or β-position using calculations based on first-principles time-dependent density functional theory. In contrast common perception, find that bearing an...
