We previously found that two magnesium(II) phthalocyanine (Mg(Pc))–based nano/microcrystals fabricated by nanoscale electrocrystallization exhibit finite gate–field responses despite their high conductivity. To clarify the origin of these unusual characteristics, we investigated the electronic structures and electrical properties of the corresponding bulk crystals. The results revealed that, although continuous charge transport is restricted by electron correlation and non–uniform π–π overlap, the crystals possess charge carriers introduced by electrochemical oxidation. This characteristic electronic structure is suggested to be responsible for both the high conductivity and the gate–field response.
