Novel
bisboron complexes of bidentate ligands consisting of 1,4-benzoquinone
and two pyrrole rings were synthesized by using a simple two-step
reaction. In solution, the bisboron complexes showed absorption maxima
at ∼620 and 800 nm, which were attributed to the allowed S0 → S2 and forbidden S0 →
S1 transitions, respectively. The bisboron complexes did
not show any fluorescence, probably because of their highly symmetrical
structure which forbids the S0 → S1 transition.
Bisboron complexes underwent a two-electron reduction to yield the
corresponding aromatic dianion, which showed absorption maxima at
∼410 nm.
