Photophysics of 1,8-naphthalimide/Ln(III) dyads (Ln = Eu, Gd): naphthalimide → Eu(III) energy-transfer from both singlet and triplet states.

Transient absorption and time resolved luminescence spectroscopy were used to study photophysical processes in the macrocycle-appended 1,8-naphthalimide compound H3L, and its Eu(III) and Gd(III) complexes Eu·L and Gd·L, in particular the naphthalimide-Eu(III) energy-transfer process. In all cases aggregation of the naphthalimide chromophores results in a low-energy emission feature in the 470-5...

Electronic effects on singlet-triplet energy splittings in aryl-cyclopentadienylidenes

Energy gaps, AXsar (X=E, H and G) (AX.,.,-=lia,„,,,InrX“dpka,) between single (s) and triplet (I) states werecalculated at B3LTP/6-3 I 1.HO" level of theory. Our results showed that electron donating substituents(G = -NHz, -OH. -CH), -F, -Cl and -Br) at phenyl group cause to increase and electron withdrawingsubstiluents (G -CF2. and -NO:) lead to decrease the singlet-triplet energy gaps of Ar -...

Singlet-Singlet, Triplet-Singlet, and Triplet-Triplet Energy Transfers. Evidence for Triplet Migration among Pendant Phenyl Groups of Polystyrene

Chemiluminescent techniques have been employed to investigate electronic energy transfer from ketone donors (acetone, acetophenone) to acceptors (e.g., 9,lO-diphenylanthracene and biphenyl) in films of polystyrene and polymethyl methacrylate at 50 "C. Tetramethyl-l,2-dioxetane and 3,4-diphenyl-3,4-dimethyldioxetane were used to generate excited (singlet and triplet) acetone and (triplet) acetop...

Photocatalytic degradation of water pollutant dye by solid state synthesized Ni1-xLnxSb2O6 (Ln=Eu, Gd, Ho and Yb) nanocomposites

Nanostructured Ni1-xLnxSb2O6 (Ln = Eu, Gd, Ho and Yb) powders were synthesized via stoichiometric 1:2 Ni:Sb molar ratio by solid state reaction at 800 ºC for 8 h using Ni(NO3)2, Sb2O3, Eu2O3, Gd2O3 and Ho2O3 raw materials. The synthesized materials were characterized by X-ray diffraction (XRD) technique. Structural analyses were done by FullProf program employing profile matching with constant ...
