摘要	A large area, aligned, ordered, -conjugated film of a liquid crystalline bi-1,3,4-oxadiazole derivative (BOXD-5) (up to several square millimeters) with polarized fluorescence (Imax/Imin of 6.0, F = 72%) and a deep blue amplified spontaneous emission (ASE) ( = 405 nm, threshold of about 2 kW cm-2) can be easily obtained upon cooling from its nematic phase with homeotropic texture in air at room temperature without the help of an alignment layer. The laser damaged aligned BOXD-5 film sandwiched between untreated glass slides can "self heal" through an easy heating-cooling thermal process. Neither the polarized fluorescence nor the ASE phenomenon were observed in the vacuum evaporated film. The directional - interactions between the 1,3,4-oxadiazole rings and phenyl rings, and its peculiar mesophase sequence cooperatively sustain a large area, aligned, ordered, -conjugated film with polarized fluorescence and an ASE. This journal is The Royal Society of Chemistry 2013.
