Abstract
The triplet state of tetramethylparaphenylenediamine (TMPD) dissolved at 10−5 M in aliphatic hydrocarbons was photoionized with light of photon energy ≤3.86 eV at room temperature. A combination of transient photocurrentmeasurements, transient absorption measurements, and temperature effects permitted evaluation of the pertinent kinetic parameters. A representative thermalization range of the low‐energy photoejected electron was estimated to be 180 Å and the absorption coefficient connecting triplet to continuum between 320–410 nm was estimated as 1 × 10−18 cm2.Keywords
