Structure and lateral electron hopping in osmium-tris-4,7-diphenylphenanthroline perchlorate monolayers at the air/water interface

Article Abstract:

A study obtained direct measurements of the kinetics of lateral electron hopping in Langmuir monolayers at the air/water interface through the use of two-dimensional electrochemical measurements conducted with line microelectrodes. The technique used in this experiment can be used to systematically investigate the kinetics of electron transfer process involving redox species in Langmuir monolayers where the effects of molecular orientation, intermolecular distances and solvent environment can be controlled.

Dynamic properties of supercritical C14TEMPO monolayers at the air/water interface

Article Abstract:

Monolayers of 4-tetradecaneamido-2,2,6,6-tetramethyl-1-piperidinyloxy (C14TEMPO) were investigated at the air/water interface. The C14TEMPO Langmuir monolayers allowed the 2-D voltammetric measurements of its lateral diffusion constant, D, extended into a previously inaccessible region of low surface densities with mean molecular areas A~600 angstrom(super 2)/molecule.
