Synthesis and electronic properties of isotruxene-derived star-shaped ladder-type oligophenylenes: bandgap tuning with two-dimensional conjugation.
The synthesis of star-shaped ladder-type oligophenylenes Sn (n = 4, 7, 10, 13, and 16), where n is the number of pi-conjugated phenylene rings, is reported. The two-dimensional conjugation interactions in Sn result in a lower bandgap for S16 than the currently known ladder-type poly(p-phenylene)s (LPPPs).
