Real-Time Bioluminescence Imaging of Glycans on Live Cells

Cell-surface glycans are attractive targets for molecule imaging due to their reflection of cellular processes associated with development and disease progression. In this paper, we describe the design, synthesis, and biological application of a new phosph ...

N-Aryl Chromophore Ligands for Bright Europium Luminescence

Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva

Sterically hindered N-aryl-benzimidazole pyridine-2-carboxylic acids (aryl = phenyl, 4-biphenyl, 2-naphthyl) readily form homoleptic, neutral, nine-coordinate europium complexes which display efficient sensitized luminescence in solid state and in dichloro ...

White-light phosphorescence emission from a single molecule: application to OLED

Michael Graetzel, Mohammad Khaja Nazeeruddin, Kuppuswamy Kalyanasundaram

A simple mononuclear cyclometallated iridium(III) complex exhibits white photo- and electro-luminescence in the wavelength range from 440 to 800 nm, which originates from a single emitting excited state of mixed character. ...

Dipole Moment of Water in Highly Vibrationally Excited States: Analysis of Photofragment Quantum-Beat Spectroscopy Measurements Using a Local-Mode Hamiltonian

Andrea Callegari, Patrice Theulé

We present here the analysis of experimental Stark effect measurements made using photofragment quantum beat spectroscopy on the 14,0->, 15,0->, 18,0+> and 14,0-> 12 > vibrational states of H2O [Callegari, A.; et al. Science 2002, 297, 993.]. To link the m ...

A ruthenium-based metallostar: synthesis, sensitized luminescence and 1H relaxivity

Jean-Claude Bünzli, Lothar Helm, Alain Borel, Loïck Moriggi, Annina Aebischer

Ru-based metallostars Na4{Ru[Ln2bpy-DTTA2(H2O)4]3} (Ln = Y, Gd, and Eu) have been self-assembled in aqueous solution and their relaxivity and optical properties unravelled. The ynthesis and the purification of the new, highly stable heptametallic entities ...

2,2’-Bipyrimidine as Efficient Sensitizer of the Solid-State Luminescence of Lanthanide and Uranyl Ions from Visible to Near-Infrared

Jean-Claude Bünzli, Frédéric Gumy

Treatment of Ln(NO3)3.nH2O with 1 or 2 equiv 2,2-bipyrimidine (BPM) in dry THF readily afforded the monometallic complexes [Ln(NO3)3(bpm)2] (Ln=Eu, Gd, Dy, Tm) or [Ln(NO3)3(bpm)2]THF (Ln=Eu, Tb, Er, Yb) after recrystallization from MeOH or THF, respectivel ...

Novel Oxygen Selective Complexes for Optical Oxygen Sensing

Michael Graetzel, Mohammad Khaja Nazeeruddin

Novel optical sensing films for oxygen based on highly luminescent iridium (III) and ruthenium (II) complexes have been developed. These demonstrate excellent long-term photostability (several months) when incorporated into polystyrene membranes. The influ ...

Dynamic disorder in horseradish peroxidase observed with total internal reflection fluorescence correlation spectroscopy

Theo Lasser, Kai Hassler

This paper discusses the application of objective-type total internal reflection fluorescence correlation spectroscopy (TIR-FCS) to the study of the kinetics of immobilized horseradish peroxidase on a single molecule level. Objective-type TIR-FCS combines ...
