Push-pull dioxaborine as fluorescent molecular rotor: far-red fluorogenic probe for ligand-receptor interactions

Iuliia Karpenko

Fluorescent solvatochromic dyes and molecular rotors have attracted considerable attention as fluorogenic probes because of background-free detection of biomolecules in live cells in no-wash conditions. Herein, we introduce a push-pull boron-containing (di ...

Preparation, kinetics, mechanism and properties of semi-transparent photocatalytic stable films active in dye degradation

César Pulgarin, Juan Kiwi, Laura Victoria Suárez Murillo, Christophe Roussel

The photocatalytic activity, mechanism and characterization of polyethylene-TiO2 films (PE-TiO2) during the discoloration/degradation of methylene blue (MB) are reported in this study. PE-TiO2 films were prepared at moderate temperatures (similar to 90 deg ...

Optical properties of small metal clusters

Chongqi Yu

This thesis is devoted to the study of the optical properties of small metal clusters and metal cluster organic compounds. For this purpose a ultra-high vacuum (UHV) experimental apparatus has been built which allows for the deposition of mass selected neu ...

Long-Range π-Conjugation in Phenothiazine-containing Donor-Acceptor Dyes for Application in Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Carole Graetzel, Jinhyun Kim, Thomas Moehl, Mateusz Barnaba Wielopolski, Yuxiang Yu

Four organic donor–π-bridge–acceptor dyes containing phenothiazine as a spacer and cyanoacrylic acid as an acceptor were synthesized and tested as sensitizers in dye-sensitized solar cells (DSCs). The influence of iodide- and cobalt-based redox electrolyte ...

Novel Chemosensors for Biologically Important Analytes

Ziya Köstereli

In this work, fluorescent-based chemosensors for the detection of important analytes in aqueous solution are described. The sensors are based on different detection concepts, including analyte-induced aggregation/de-aggregation, pattern-based sensing and m ...

Optical spectroscopy of the bladder washout fluid to optimize fluorescence cystoscopy with Hexvix

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Blaise Lovisa, Carla Martoccia

Fluorescence cystoscopy enhances detection of early bladder cancer. Water used to inflate the bladder during the procedure rapidly contains urine, which may contain fluorochromes. This frequently degrades fluorescence images. Samples of bladder washout flu ...

Spectral cola or how to turn green laser light red

Thibaud Humair, Xavier François Mettan, Csaba Forro

A green laser pointer shone through a glass of cola will appear red when looking from above the glass. Lowering the laser so that it is deeper in the cola, the colour will vary from orange to deep red. Fluorescence and absorption spectra were recorded cons ...
