ABSTRACT

Pentacene and its derivatives have unique optoelectronic properties, which make them promising

materials in molecular electronic devices such as organic light-emitting diodes (OLEDs)1 and

organic field-effect transistors (OFETs)2. In this presentation, we report our recent studies on the

functionalization of pentacene-5,7,12,14-teraone by olefination and transition-metal catalyzed

cross-coupling reactions. A new class of pi-conjugated donor/acceptor systems has been

synthesized using pentacenetetraone as the precursor, while the structural, electronic and redox

properties of these compounds were characterized by spectroscopic analyses in conjunction with

density functional theory (DFT) calculations.3-4
