This study presents the preparation of a new phthalonitrile derivative namely 3-(4-(trifluoromethoxy)thiophenoxy)phthalonitrile (1) and a series of its metallated phthalocyanines (M = Zn (II) (1a) and In(III) (1b)). In addition, the peripheral analog of the indium phthalocyanine chloride (2b) was newly synthesized. Characterization of the resulting compounds was carried out by utilizing various spectroscopic methods such as FT-IR, H NMR and UV-Vis spectroscopy. The influence of concentration on aggregation properties of compound 1a was investigated at different concentrations of DMSO. The effect of solvent type on aggregation properties of compound 1a was studied, as well. According to the referred procedures, the macrocyclic molecules (2a, 3a-b and 4a-b) were prepared. The effect of some parameters including metal ion, the position of the substituent and the connected atom (oxo or thio) on photochemical and photophysical features of compounds (1a-b, 2a-b, 3a-b, and 4a-b) was studied for evaluation of their potential as a photosensitizer in PDT, comparatively. The highest singlet oxygen quantum yields (Φ = 0.71 for 1a and 0.80 for 2b) were obtained for complexes 1a and 1b in DMSO. The photophysical and photochemical features of the studied macromolecules are therefore suitable for photodynamic therapy applications.

To observe the chemical mechanical polishing (CMP) process at the atomic scale, reactive force field molecular dynamics (ReaxFF-MD) was employed to simulate the polishing of 6 H-SiC under three conditions: dry, pure water, and HO solution. This study examined the reactants on the surface of 6 H-SiC during the reaction in the HO solution, along with the dissociation and adsorption processes of HO and water molecules. The mechanisms for atom removal during the CMP process were elucidated.

CYP105A1 exhibits monooxygenase activity to a wide variety of structurally different substrates with regio- and stereospecificity, making its application range broad. Our previous studies have shown that CYP105A1 wild type and its variants metabolize 12 types of nonsteroidal anti-inflammatory drugs (NSAIDs). In particular, the R84A variant exhibited a high activity against many NSAIDs.

Magnetic Weyl semimetals (WSMs) have recently attracted much attention due to their potential in realizing strong anomalous Hall effects. Yet, how to design such systems remains unclear. Based on first-principles calculations, we show here that the ferromagnetic half-metallic compound InCoSehas several pairs of Weyl points and is hence a good candidate for magnetic WSM.

All-carbon quaternary and tertiary stereocenters connected at the C2-position of functionalizable C3-alkylated indole nucleus are commonly occurring frameworks found in many indole alkaloids of medicinal importance. Their direct access is scarcely reported, a long-standing problem, and developing a unique yet simple method can pave the pathway to an entirely different retrosynthetic route for the total synthesis of these alkaloids. Herein, this problem is addressed by developing an unprecedented branch-selective allylation strategy employing a broad range of structurally and electronically different 3-alkenyl-indoles and allylboronic acids.
