One-Pot Photoreactions: A Source for Metal-Polymer Nanocomposites.

We have developed a one-step, one-pot photo-induced method for synthesizing metal/polymer nanocomposites. This approach utilizes the photolysis of a bis(acyl)phosphane oxide (BAPO) photoinitiator. Two types of radicals are formed.

Polystyrene-bound AlCl - a catalyst for the solvent-free synthesis of aryl-substituted tetrazoles.

Tetrazole moieties are components of various pharmacologically active molecules. Several synthetic protocols for the synthesis of tetrazoles have been developed. Among those, the reaction of organic nitriles with azides catalyzed by Lewis acids (LAs) provides a convenient access.

A versatile method for the determination of photochemical quantum yields via online UV-Vis spectroscopy.

We have developed a simple method for determining the quantum yields of photo-induced reactions. Our setup features a fibre coupled UV-Vis spectrometer, LED irradiation sources, and a calibrated spectrophotometer for precise measurements of the LED photon flux. The initial slope in time-resolved absorbance profiles provides the quantum yield.
