title: Ph₂N-susbtituted ethylene-bridged p-phenylene oligomers: synthesis and photophysical and redox properties.
abstract: For a series of p-phenylene-based oligomers terminated with two triphenylamines, their absorption, photoluminescence, and band gaps show a pattern of extensive π-conjugation with increasing array size. Oligomers with large central arrays have greater quantum yields than their small analogues. Cyclic voltammetric (CV) measurements indicated two-step oxidations of the two diphenylamino groups for compounds 1-5 and one-step oxidations for the two amines of large oligomers 6 and 7.
