Abstract

7,7,8,8-Tetracyanoquinodimethan(TCNQ) was adsorbed on the surfaces of alumina and titania from three basic solvents. The amount of TCNQ adsorbed decreased with an increase in the acid-base interaction between TCNQ and the basic solvent for both metal oxides. The TCNQ anion radicals were formed as a result of electron transfer from the metal oxide surfaces to adsorbed TCNQ. Further, the concentration of TCNQ anion radicals formed on the oxides after the TCNQ adsorption decreased also with an increase in the acid-base interaction between TCNQ and the basic solvent.
