Ultrafast Intramolecular Charge Separation in Tetrapyrazinoporphyrazines Controls the Quantum Yields of Fluorescence and Singlet Oxygen

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Modeling quantum effects in photosynthetic charge separation

Nature used light as a source of energy. Organisms like plants and bacteria rely on photosynthesis to power their activity. Light is absorbed by pigment molecules, which are part of large protein complexes. The initially absorbed photon creates an energy packet, which moves through the complex towards a reaction center, where charge separation takes place [1]. Over the past ten years, the role ...

Photoirradiation wavelength dependence of cycloreversion quantum yields of diarylethenes.

The cycloreversion quantum yields of compounds 1b and 2b increased upon irradiation with light at shorter wavelengths. The irradiation wavelength dependence is ascribed to the energy barrier on the 2A potential energy surface in the excited electronic state.
