Waveguide and ultralow-threshold amplified spontaneous emission in an aligned ordered solid state based on a highly fluorescent twin-tapered bi-1,3,4-oxadiazole derivative.

Strong fluorescence and amplified spontaneous emissions (ASE) both in solution and aligned ordered solid state were observed from a twin-tapered bi-1,3,4-oxadiazole derivative, which could be used in preparing functional supramolecular architectures with ultralow-threshold ASE.
