One small step in synthesis, a big leap in charge mobility: diphenylethenyl substituted triphenylamines

摘要

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)1 s~(-1)), are reported.
