Soluble Diazaiptycenes: Materials for Solution-Processed Organic Electronics

The synthesis and
characterization of soluble azaiptycenes is reported.
Optical and physical properties were studied and compared with those
of the structurally consanguine azaacenes. Electrochemical experiments
and quantum-chemical calculations revealed the electronic structure
of the iptycene derivatives. Their crystallization behavior was examined.
A highly fluorescent amorphous diazatetracene derivative was integrated
into a simple organic light-emitting diode, showing enhanced performance
compared with that of previously reported, structurally similar tetracenes.
