Face-to-face pacman-type porphyrin-fullerene dyads: design, synthesis, charge-transfer interactions, and photophysical studies
(John Wiley and Sons, 2008-01-01)Pacman-type face-to-face zinc-porphyrin-fullerene dyads have been newly synthesized and studied. Owing to the close proximity of the donor and acceptor entities, strong pi-pi intramolecular interactions between the porphyrin ... -
A facile cross-linking approach to fabricate durable and self-healing superhydrophobic coatings of SiO2-PVA@PDMS on cotton textile
(Elsevier, 2020-07-05)Superhydrophobic surfaces with long-lasting stability through simple fabrication procedures have attracted considerable attention. The application of existing superhydrophobic surfaces is limited, considering the use of ... -
Fast and effective ion mobility-mass spectrometry separation of D-amino-acid-containing peptides
(American Chemical Society, 2017-11-01)Despite often minute concentrations in vivo, d-amino acid containing peptides (DAACPs) are crucial to many life processes. Standard proteomics protocols fail to detect them as d/l substitutions do not affect the peptide ... -
Fenamate protects against 1-methyl-4-phenylpyridinium-induced apoptosis in dopaminergic MN9D cells
(American Chemical Society, 2018)Parkinson's disease (PD) is a neurodegenerative disease caused by the death of dopaminergic neurons in substania nigra. While the causes of PD under mol. level have not been fully identified, it is necessary to identify ... -
Flow-gated capillary electrophoresis: a powerful technique for rapid and efficient chemical separation
(Royal Society of Chemistry, 2018-05-30)Flow-gated capillary electrophoresis (CE) is a hybrid of conventional and microchip CE since it employs a fused silica capillary as the separation channel while taking advantage of the rapid flow-gated injection that is ... -
Fluorophore(s) appended fullerene dyads and triads for probing photoinduced energy transfer: syntheses, electronic structure, and fluorescence studies
(Springer, 2006-01-01)Fullerene, C(60) was functionalized to possess one or two fluorophore entities. The fluorophore-fullerene dyads thus synthesized contain either a naphthalene, pyrene, or fluorene entity while the triads contain either a ... -
Flux growth of phosphide and arsenide crystals
(Frontiers Media S.A., 2020-04-02)Flux crystal growth has been widely applied to explore new phases and grow crystals of emerging materials. To accommodate the needs of high-quality single crystals, the flux crystal growth should be reliable, controllable, ... -
Forbidden Electronic Transitions between the Singlet Ground State and the Triplet Excited State of Pt(II) Complexes
(American Chemical Society, 1998-07-13)Direct access to the triplet emitting state from the ground state is observed for Pt(II) complexes containing heterocyclic (CwedgeC', CwedgeN, NwedgeN') and bis(diphenylphosphino)alkane (PwedgeP') ligands. Extinction ... -
Formation of [b(n) + 17 + Ag]+ product ions from Ag+ cationized native and acetylated peptides
(John Wiley and Sons, 2002-09-01)We compared the tandem mass spectra of a range of native and acetylated Ag(+) cationized peptides to determine the influence of the derivatization step on the abundance of the [b(n) + 17 + Ag](+) product ions. Using ... -
Formation of [b3 - 1 + cat]+ ions from metal-cationized tetrapeptides containing beta-alanine, gamma-aminobutyric acid or epsilon-aminocaproic acid residues
(John Wiley and Sons, 2008-11-01)The presence and position of a single beta-alanine (betaA), gamma-aminobutyric acid (gammaABu) or epsilon-aminocaproic acid (Cap) residue has been shown to have a significant influence on the formation of b(n)+ and y(n)+ ... -
Formation, spectral, electrochemical, and photochemical behavior of zinc N-confused porphyrin coordinated to imidazole functionalized fullerene dyads
(American Chemical Society, 2006-06-26)Donor-acceptor dyads were constructed using zinc N-confused porphyrin (ZnNCP), a structural isomer of zinc tetraphenylporphyrin, as a donor, and fullerene as an electron acceptor. Two derivatives, pyridine-coordinated zinc ... -
