"Graphene" – a new carbonaceous material – is
distinguished from conventional electronic systems such as graphite due
to its exceptional features, e.g., a large magnetic moment around the
zigzag edges and massless Dirac fermion, stimulating development of
future electronic/spintronic devices. Several unique features of
graphene are closely connected with the "open-shell character",
which originates in the "instability of chemical bonds" in π-conjugated system with unconventional spin states and
strongly correlates with the topology of π-electron
array, especially aromatic sextet formation. This symposium focuses on recent
hot topics regarding unique physical and chemical properties derived from
pseudo and real spins in π-conjugated
compounds, toward collaboration between theory, computational modeling
and experiment. A wide range
of compounds from small conjugated/aromatic molecules and inorganic metal
complexes to nano- and large-size graphenes will be covered, and origin
of the open-shell character as well as functional properties such as
electron conductivity, optical and magnetic properties will be
concentrated as important domains in the symposium.
