| 中文摘要 | Three polymorphs of tris(dibenzoylmethane) gallium were characterized by optical microscopy, absorption, photoluminescence (PL) and used for electroluminescent devices (EL). PL spectrum of the thin film is composed of both gamma-type yellow emission and beta-type blue emission, but only gamma-type yellow EL emission was observed, indicating the polymorphic counterpart beta-type with weaker pi-pi interactions was defeated in competition for EL generation. A comparison of the three polymorphic crystal structures reveals that a zigzag channel from intermolecular pi-pi interaction at a distance of 3.6-3.7 angstrom to intramolecular bond-bond conjugation may dominate the charge transport and be responsible for the yellow EL emission.
