Single-electron transistor of a single organic molecule with access to several redox states

Article Abstract:

Results indicate that single-electron-transistor measurement derived molecular electronic levels are strongly perturbed than those in solution, which leads to a reduction of the gap between the highest and the lowest molecular orbitals. Data suggest this may be due to the charges generated in the source and the drain electrodes resulting in the deposition of charges on the molecule.

Spatially resolved observation of crystal-face-dependent catalysis by single turnover counting

Article Abstract:

A real time monitoring of the chemical transformation of individual organic molecules by fluorescence microscopy is adapted to monitor reactions catalyzed by crystal of a layered hydroxide immersed in reagent solution. The results revealed that ester hydrolysis proceeds on a lateral crystal faces, while transesterification occurs on the entire outer crystal surface.

Usage, Fluorescence microscopy

Solid awakening

Article Abstract:

The author discusses the development of an organic solid or crystal that exhibits excellent chain reactivity on being kept under light. Such organic solids are found to exhibit unimolecular, as well as bimolecular reactivity and hence can be employed in the sensor-based materials and other applications.
