Photocatalytic depolymerization (PCDP) of rice husk (RH) over TiO 2 in H2O2 aqueous solution under ultraviolet irradiation was investigated. The reaction mixture was fractionated into different extracts by filtration and subsequent sequential extraction with different organic solvents. In total, 172 organic compounds were identified in the extracts with GC/MS. The compounds can be classified into alkanes, alkenes, arenes, non-substituted alkanols, substituted alkanols, alkenols, phenols, alkanals, alkenals, benzaldehydes, ketones, carboxylic acids, alkanoates, phthalates, nitrogen-containing organic compounds, sulfur-containing organic compounds and other species. Alkanes are the most abundant in the group components. They resulted from the degradation of waxes in RH. Aldehydes and ketones were also detected with high relative contents, most of which were derived from cellulose, hemicellulose and waxes. Phthalates and arenes resulted from lignin degradation. Lignin-wax and hemicellulose-wax interlinkages are proposed to be new structures. According to the species identified in the extracts, the mechanisms for photocatalytic oxidation of benzene ring-containing compounds are proposed. The PCDP of RH provides an alternative way to obtain value-added chemicals from biomass with low energy consumption and under eco-friendly conditions.

Luminescent materials simultaneously exhibiting superior luminescence efficiency, thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) properties in the solid state are eagerly required for highly efficient non-doped organic light-emitting diodes (OLEDs). Herein, two new emitters, namely ND-AC and CND-AC, featuring a naphthyridine or cyano-naphthyridine segment as the electron acceptor and an acridine unit as the electron donor were designed, synthesized and investigated. The nearly orthogonal molecular configuration of the target emitters not only endows them with small energy differences between singlet and triplet states for ensuring TADF character but also affords a remarkable AIE feature. Due to the high photoluminescence quantum yields, and excellent TADF and AIE characteristics, the doped and non-doped OLEDs based on ND-AC exhibit outstanding performances with maximum external quantum efficiencies of 16.8% and 12.0%, respectively. These results demonstrate that the naphthyridine-based emitters have a promising application in OLEDs.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5423-54-1, help many people in the next few years.Recommanded Product: 5423-54-1

A series of novel 7-[3-(N?-alkoxycarbamimidoyl)-4-(alkoxyimino) pyrrolidin-1-yl] fluoroquinolone derivatives were designed, synthesized and characterized by 1H NMR, MS and HRMS. These fluoroquinolones were screened for their in vitro antibacterial activity. Most of them exhibit good potency in inhibiting the growth of Staphylococcus aureus and Staphylococcus epidermidis (MIC: 0.06-4.00 mug/mL). The activity of compounds 33 and 43 against S. aureus including MRSA and S. epidermidis including MRSE (MIC: 0.06-0.125 mug/mL) is more than or comparable to the reference drugs levofloxacin and gemifloxacin. In addition, compound 33 is 32 and 16-32 fold more potent than both the reference drugs against Enterococcus faecium 08-7 and Klebsiella pneumoniae 09-22, respectively.

It is well-recognized that N-heterocyclic carbene (NHC) ligands have provided a new dimension to the design of homogeneous catalysts. Part of the success of this type of ligands resides in the limitless access to a variety of topologies with tuned electronic properties, but also in the ability of a family of NHCs that are able to adapt their properties to the specific requirements of individual catalytic transformations. The term “smart” is used here to refer to switchable, multifunctional, adaptable, or tunable ligands and, in general, to all those ligands that are able to modify their steric or electronic properties to fulfill the requirements of a defined catalytic reaction. The purpose of this review is to comprehensively describe all types of smart NHC ligands by focusing attention on the catalytically relevant ligand-based reactivity.
