Comparison of thermal and optical electron-transfer barriers in ruthenium redox polyether melts

Article Abstract:

Experimental determinations and comparison of thermal and optical energy barriers for electron transfers in a specific redox polyether melt, namely the metal complex Ru(bpy350)2(CN)2 where bpy350 is 4,4'-dimethyl-2,2'-dipridyl alkyl-bonded to 350 MW polyethylene glycol monomethyl ether is described. The energy barrier results revealed that the observed thermal electron transfer barrier is only an apparent one, being instead controlled by ion atmosphere relaxation processes, whereas the optical energy barrier corresponds to that of the actual electron-transfer process itself.

Effect of position of polyether attachment on the electron self-exchange activation barrier energies of redox polyether hybrid molten salts

Article Abstract:

Results show that activation of homogeneous electron transfers in molten salts encounter large activation barriers. Data further indicate that physical diffusion rates and viscosity is dependent on the number of ethylene oxide segments in the polyether tails.
