Time-resolved microwave conductivity TRMC

Time-resolved microwave conductivity TRMC) Technique allowing the quantitative and qualitative detection of radiation-induced charge separation by time-re-solved measurement of the changes in microwave absorption resulting from the production and decay of charged and dipolar molecular entities. [Pg.349]

Fig. 16.8 Charge recombination lifetimes in the compounds shown in the inset in dioxane solvent. (J. M. Warman, M. P. de Haas, J. W. Verhoeven, and M. N. Paddon-Row, Adv. Chem. Phys. 106, Electron transfer—from isolated molecules to bio-molecules, Part I, edited by J. JortnerandM. Bixon (Wiley, New York, 1999). The technique used is time-resolved microwave conductivity (TRMC), in which the change in dielectric response of a solution is monitored following photoinduced electron transfer—a charge separation process that changes the solute molecular dipole. The lifetimes shown as a function of bridge length (number of a-bonds separating the donor and acceptor sites in the compounds shown in the inset) are for the back electron transfer (charge recombination) process.

They are fully presented in several texts, see for example the compilation of Baxendale and Busi [15]. To summarise, the detection techniques used in this field are mainly D.C. and time resolved microwave conductivity (TRMC), and Optical Absorption and Emission Spectroscopy. [Pg.116]

A separate development of the TRMC techniques was their application to the study of dipolar and excitonic species formed on flash-photolysis of dilute solutions and, more recently, to charge transport and charge separation in thin (aligned) solid films. In the present review we restrict ourselves to results that we have obtained on pulse-irradiated materials, for which the method has become known as the pulse-radiolysis time-resolved microwave conductivity or PR-TBAIC technique. [Pg.162]

Van de Craats et al. used the pulse-radiolysis time resolved microwave conductivity (PR-TRMC) technique to study the charge-transport properties of [ (Ci2H250)gPc 2Lu]. Their results showed an increase in charge carrier mobility at the crystalline solid to Col mesophase... [Pg.102]
