4-Azido-2-nitrophenyl [α-32P]pyrophosphate (azido-[α-32p]PPi) mimics ADP and PP1 by some of its binding properties when assayed in the absence of photoirradiation with mitochondrial Fl-ATPase. Upon photoirradiation, both α- and β-subunits of F1-ATPase were covalently labelled. Following chem...
Suitable conditions were sought for the synthesis of various 2-[11,14C]methyl-fatty acids by malonic ester synthesis and acetoacetic ester synthesis, both involving radio-methylation with [11,14C]Ch3I. The malonic ester synthesis gave 2-[11C]methyl-fatty acids with over 60% decay-corrected yield...
N-Hydroxymethyl [carbonyl-14C] dimethoate (0.43 ppm) and N-desmethyl [carbonyl-14C] dimethoate (0.50 ppm) were stem-injected into bean plants (Phaseolus vulgaris) in two separate experiments. Plants were harvested periodically, extracted, fractionated, and analyzed for metabolites. The resulting...
The first total syntheses of (−)-dysibetaine CPa and the antipode have been achieved using enantioselective solvolysis of meso-cyclic anhydride mediated by quinine derivative as an organocatalyst. The synthesis features a demonstration of an enantiodivergent organic synthesis of both enantiomers...
Our aim was to develop multiwalled carbon nanotubes (MWCNTs)-based nanoconstructs for the codelivery of N-desmethyl tamoxifen (N-TAM) and a mild P-gp efflux inhibitor, i.e., quercetin (QT) to treat multiple drug resistant (MDR) cancer cells. The hypothesis banks on three-tier attack on the MDR m...
The solid state structures of the (—)‐n‐heptylcarbamate of geneseroline and its hydrochloride salt were determined by single crystal X‐ray diffraction analysis. Both compounds gave crystals belonging to the orthorhombic P212121 space group with a = 27.597(7) Å, b = 8.899(2) Å, c = 9.290(2) Å...
Structural based molecular docking approach revealed the findings of 2-(phenoxymethyl) -5-phenyl-1,3,4-oxadiazole derivatives. The compounds (7a-o) were synthesized and characterized well by using conventional methods. The compounds, 7b and 7m were reconfirmed through single crystal XRD analysis...
Staphylococcus aureus and Mycobacterium tuberculosis are major causative agents responsible for serious nosocomial and community-acquired infections impacting healthcare systems globally. Over several decades, these pathogens have developed resistance to multiple antibiotics significantly affect...
A common strategy to synthesize 4/6-(4-(4-methylpiperazin-1-yl)-6-(4-(4-oxo-2-phenylthiazolidin-3-yl)phenyl)-1,3,5-triazin-2-yloxy)benzonitriles/nicotinonitriles was developed by applying an efficient palladium-catalyzed C–C Suzuki coupling. Moreover, the synthesized compounds were also tested ...
The preparation of N-phenylbenzamidine 3a from the reaction between benzonitrile 1a and aniline in the presence of AlCl3 is reinvestigated with respect to mode of reagent addition, reaction temperature and Lewis acid catalysis. Pre-forming the nitrile-Lewis acid complex prior to the addition of ...
The device performances including the emission spectrum and device efficiency of blue-emitting β-phase poly(9,9-di-n-octylfluorene) (β-PFO) annealed at different temperatures from 40 to 160 °C are investigated. The relatively unchanged β-PFO content along with dominating photoluminescence (P...
The interactions of thermally evaporated aluminium with spin-casted film of poly[2,7-(9,9-dihexylfluorene)-co-alt-2,5-(decylthiophene)] (PFT), a novel blue light-emitting copolymer, were studied in situ by X-ray photoelectron spectroscopy (XPS). The changes in the C 1s, S 2p, O 1s and Al 2p core...
We have used transient photoinduced absorption (PA) in the ms time regime to study the recombination kinetics of long lived photoexcitations in poly(9,9-dihexylfluorene-co-benzothiadiazole) (F6BT). The PA spectrum shows a high energy band (HE) peaked at 1.44 eV associated with triplet excitons, ...
We prepared and characterized three new copoly(aryl ether)s (P1–P3) consisting of alternate electron-transporting 2,7-bis(3-(trifluoromethyl)phenyl)-9,9-dihexylfluorene and hole-transporting fluorophores (P1: 3,6-distyryl-N-2-ethylhexylcarbazole; P2: 2,7-distyryl-9,9-dihexylfluorene; P3: 1,4-di...
Three new hyperbranched polymers (P1–P3) were prepared by copolymerization of tribromoaryl moieties (triphenylamine, carbazole and fluorene moieties) with 9,9-dihexylfluorene-2,7-bis(trimethyleneborate) from “A2 + B3” approach based on Suzuki polycondensation reaction. They are soluble in com...
In this study the optical property and film morphology of a conjugated polymer, poly(9,9-dihexylfluorene-alt-2,5-dihexyloxybenzene) (PF6OC6), are investigated. It is found that the intensity of the 0–1 emission relative to the 0–0 emission in the PL spectra and the full width at the half-maxim...
We prepared three new poly(9,9-dihexylfluorene) derivatives (P1–P3) containing kinked aromatic triazole (triphenyl-1,2,4-triazole derivative) via Suzuki coupling polymerization. These copolymers were soluble in common organic solvents and showed high decomposition temperatures (Td = 416–454 °...
Quaternary lead halide CsPbBr1.5I1.5 perovskite quantum dots (PQDs) with cubic shapes and emission wavelength at 566 nm were synthesized by hot injection and carefully characterized to better compensate with blue co-oligomer for white light emission. With a very simple device structure, the elec...
Some aspects of the energy transfer processes between poly(9,9′-dihexylfluorene-2,2-dyil) and MEH-PPV in solutions of good and poor solvents and in solid state blends are addressed. The resonant non-radiative energy transfer in solution is discussed in terms of the Förster dynamic model and usi...
The synthesis of a crosslinkable poly(9,9-dihexylfluorene) derivative is reported. Vinyl ether moieties allow for photolithographic patterning, resulting in an immiscible polyfluorene network, which enables subsequent wet thin-film processing. The metastable β-phase morphology, inherent to most...
