In situ electrochemical fluorescence studies of PPV

Article Abstract:

In situ electrochemical steady-state fluorescence spectroscopy is used to study the electrochemical and spectroelectrochemical properties of poly[2-methoxy-5-(3'-7'-dimethyloctyloxy)-1,4-phenylene-vinylene](MDMO-PPV). The change of the fluorescence during non-Faradic relaxation has followed first-order kinetics that is similar to the variation of a gel in the course of shrinking.

Rotationally resolved electronic spectra of 2- and 3-methylanisole in the gas phase: A study of methyl group internal rotation

Article Abstract:

The low and high resolution S1 <-- S0 fluorescence excitation spectra of 2-methylanisole (2MA) and 3-methylanisole (3MA), as isolated species in the gas phase, are described. The spectra show that the position of substitution of the methoxy group on the aromatic ring determines the preferred orientation and torsional barrier height of the attached methyl group.

Surface plasmon-coupled emission and Fabry-Perot resonance in the sample layer: A theoretical approach

Article Abstract:

A theoretical approach is used to investigate the coupling of surface plasmon-coupled emission to Fabry-Perot resonance in the sample layer. It is found that this approach should be well-suited for directing emission from fluorophores in specific directions.
