Entwicklung neuer photoleitender Polymersysteme
In order to obtain fast organic photoconductors with a charge carrier mobility >10"-"4 cm"2/Vxs and with improved processing behaviour, liquid crystalline systems were prepared and characterized. Besides some calamitic liquid crystals with smectic and nematic mesophases, mainly discotic columnar mesophases with efficient charge transport along the one-dimensional ordered columns were synthezised and subsequently studied in time-of-flight, transient absorption, quantum yield and steady-state photoconductivity experiments. For the studied systems structure-property relationships could be established between structure, order, mobility, doping with electron acceptors, photoconductivity and mechanic properties. It is demonstrated that doped electron-rich hexaalkyloxytriphenylenes act as excellent hole conductors with a charge carrier mobility up to 10"-"3 cm"2/Vxs in the liquid crystal phase.
