Nanosecond kinetics of the photoconductivity of liquid TMPD solutions in methylcyclohexane

The electric conductivity of N,′N,′N′,N′-tetramethyl- p-phenylenediamine solutions in methylcyclohexane induced by a 347 nm laser pulse has been studied. At temperatures < 180 K a new transient photoconductivity effect has been revealed a current peak whose duration (≈30 ns) equals the duration o...

Description
Summary:The electric conductivity of N,′N,′N′,N′-tetramethyl- p-phenylenediamine solutions in methylcyclohexane induced by a 347 nm laser pulse has been studied. At temperatures < 180 K a new transient photoconductivity effect has been revealed a current peak whose duration (≈30 ns) equals the duration of the laser pulse. The current is attributed to the electric polarization of trapped electron-cation pairs before geminate recombination.
