Electrogenerated Chemiluminescence (ECL)
Electrogenerated Chemiluminescence, ECL, involves the electrochemical generation of reactive species in solution, typically radical ions, which undergo highly exergonic reactions that are able to produce the excited state of one of the parent molecules. This program deals with one of the simplest cases in which radical ions are generated at a large electrode (i.e. we treat 1D semi-infinite diffusion) from a parent molecule by stepping the electrode between positive and negative potentials. These radical ions react in the solution space to generate the excited state which then radiates. Light emission in this simulation is not treated in absolute terms, rather, as the rate of radiative decay of the excited state. This simulation also considers the formation of multiply charged species, which is interesting since it allows the evaluation of Donor-Acceptor systems that can form these species.
