New thiophene-functionalized pyrene, peropyrene and teropyrene via a two- or four-fold alkyne annulation and their photophysical properties
We synthesized thiophene-functionalized pyrene, peropyrene, and teropyrene through a two- or four-fold alkyne annulation reaction promoted by triflic acid. All of the target compounds were fully characterized spectroscopically, ...
Estimating the donor-acceptor distance to tune the emission efficiency of luminescent lanthanide compounds
The influence of the donor朼cceptor distance燫L爋n the photophysical properties, including the emission quantum yield, of two europium complexes with the same coordination number, and thus similar microsymmetries, was ...
ZnS nanoparticles sensitize luminescence of capping-ligand bound lanthanide ions
2,6-Bis(diethylamide)-4-oxo(3-thiopropane)pyridine (BDP) and 2,6-bis(methyl ester)-4-oxo(3-thiopropane)pyridine (BMP) were synthesized. These compounds chelated LnIII爄ons and sensitized their emission. The 3:1 complexes ...
Ab initio calculations of spectroscopic constants and vibrational state lifetimes of diatomic alkali-alkaline-earth cations
We investigate the lifetimes of vibrational states of diatomic alkali-alkaline-earth cations to determine their suitability for ultracold experiments where long decoherence time and controllability by an external electric ...
Influence of thermalization on thermal conduction through molecular junctions: Computational study of PEG oligomers
Thermalization in molecular junctions and the extent to which it mediates thermal transport through the junction are explored and illustrated with computational modeling of polyethylene glycol (PEG) oligomer junctions. We ...
Synthesis and reactivity of a mononuclear non- haem cobalt(IV)-oxo complex
Terminal cobalt(IV)-oxo (Co-IV-O) species have been implicated as key intermediates in various cobalt- mediated oxidation reactions. Herein we report the photocatalytic generation of a mononuclear non- haem [(13-TMC) ...
