OLEDs are [effectively] chemiluminescent devices, so yes you can "recharge" or, more commonly "turn on and off" chemiluminescent reactions with a couple electrodes and appropriate bias voltage, aka "electrogenerated chemiluminescence" (ECL). 9,10-Diphenylanthracene (DPA, blue) and ruthenium tris bipyradine (Ru(bpy)3, orange) are a couple commonly used ECL molecules, and they take advantage of different mechanisms to produce the excited state. Not sure how detailed you want but a text reference for you: Electrogenerated Chemiluminescence by Allen J. Bard (hard copy: http://amzn.to/2l0TTtZ ordigital: https://books.google.com/books?id=3aK2sahiRY8C&printsec=frontcover#v=onepage&q&f=false). The full copy is expensive, but it may be available in univ. chem library and google books digital copy has partial text available.

Just wanted to note your triangle example isn't one of error, it's of perception. The red and blue triangles have slightly different angles and so the area difference is accounted for by the fact that the assembled "triangle" is actually not a triangle at all (in either case).

Hi Erbil, I'm really not sure how to answer your questions, but will try. Note: electrochemistry benefits a lot from a class or background in it. If you have not done electrochemistry before, you can read applications notes and get texts, but it is really useful to have a more in depth interaction with a person/persons who are familiar with it. on to your questions. First question: it is not universal but for most researchers more negative potentials are more cathodic and increase the likelihood and rate of reduction. Conversely more positive potentials are more anodic and increase the likelihood and rate of oxidation. The measure of voltage, however, is a relative measure--i.e. voltage is measured at the working electrode (WE) vs. some reference point (hence: reference electrode) and the nature of that reference point affects what reactions can occur at given voltages. As such it is impossible to say what *should* happen at a given potential without complete knowledge of the system: # electrodes, nature of reference, type of working and the [possible] electoactive species and their existing state (+1, 0, -1...). Second question: no. The Echem Analyst is an analysis program, not an experimental one (Framework is the experimental program) so editing Analyst scripts doesn't let you run any experiment. Now, if you mean is it possible to run chronoamp based off values obtained from running CV's then absolutely, yes. You can run CV, to determine which potential(s) to use for a subesequent chronoamperometry experiment then run chronoamp at the relevant potential(s) to get data, maybe to electrolyze or plate or catalyze...
