Modulating the Near-Infrared Luminescence of Neodymium and Ytterbium Complexes with Tridentate Ligands Based on Benzoxazole-Substituted 8-Hydroxyquinolines

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

An improved synthesis of 2-(2′-benzothiazole)- and 2-(2′-benzoxazole)-8-hydroxyquinoline ligands that combine a tridentate N,N,O-chelating unit for metal binding and extended chromophore for light harvesting is developed. The 2-(2′-benzoxazole)-8-hydroxyqu ...

Triplet Imaging by Modulated Excitation

Dimitri Nestor Alice Van De Ville, Theo Lasser, Kai Johnsson, Boris Hinz, Thiemo Spielmann, Aurélie Formey de Saint Louvent

We present a functional imaging method based on triplet state kinetics. The triplet state of many known fluorophores show a triplet lifetime typically in the order of ~10e-6 – 10e-3 s, 3-6 orders of magnitude longer than the associated fluorescence singlet ...

Generation and application of high power femtosecond pulses in the vibrational fingerprint region

Sylvie Roke, Hilton Barbosa De Aguiar

We present a novel high power femtosecond infrared laser source, based on a three-stage chirped-pulse amplification scheme. Owing to the high power output of the Ti:sapphire amplifiers, it becomes routinely possible to produce femtosecond infrared laser pu ...

Excited-State Dynamics of Donor−Acceptor Bridged Systems Containing a Boron−Dipyrromethene Chromophore: Interplay between Charge Separation and Reorientational Motion

Natalie Renuka Banerji, Eric Vauthey

The excited-state dynamics of a series of electron donor−acceptor bridged systems (DABS) consisting of a boron−dipyrromethene chromophore covalently linked to a dinitro-substituted triptycene has been investigated using femtosecond time-resolved spectrosco ...

Evanescent optical fluorescence excitation: the role of photonic mode density

Akihiro Sato

In this paper we will discuss a few basic concepts concerning the use of evanescent optical fields for the excitation of fluorescent chromophores placed near the interface. The observation of enhanced fluorescence from chromophores excited by surface plasm ...

Solvent and protein effects on the structure and dynamics of the rhodopsin chromophore

Ursula Röthlisberger, Leonardo Guidoni

The structure and dynamics of the retinal chromophore of rhodopsin are investigated systematically in different environments (vacuum, methanol soln., and protein binding pocket) and with different computational approaches (classical, quantum, and hybrid qu ...

Contrasting the excited-state dynamics of the photoactive yellow protein chromophore: Protein versus solvent environments

Majed Chergui, Goran Zgrablic, Stefan Haacke

Wavelength- and time-resolved fluorescence expts. have been performed on the photoactive yellow protein, the E46Q mutant, the hybrids of these proteins contg. a nonisomerizing "locked" chromophore, and the native and locked chromophores in aq. soln. The ...

Reversible site-selective labeling of membrane proteins in live cells

Horst Vogel, Rudolf Hovius, Emmanuel Guignet

Chem. and biol. labeling is fundamental for the elucidation of the function of proteins within biochem. cellular networks. In particular, fluorescent probes allow detection of mol. interactions, mobility and conformational changes of proteins in live cells ...
