One small step in synthesis, a big leap in charge mobility: diphenylethenyl substituted triphenylamines†
Abstract
Star-shaped charge transporting materials with a triphenylamine core and a varying number of diphenylethenyl sidearms, obtained using a one step synthesis procedure from commercially available and relatively inexpensive starting materials and possessing comparatively high hole drift mobility (up to 0.017 cm2 V−1 s−1), are reported.
