A novel α-pyrone derivative was synthesized. Photophysics and aggregation of the molecule were investigated. The molecule is almost non-emissive in good solvent, but strongly emissive in solid or aggregate state. The aggregate of the molecule shows blue emission and the quantum yield reaches 17%. The emission enhancement is attributed to the restriction of intramolecular rotation in aggregates according to the structure of the molecule and temperature-dependant emission spectra results.

Key words: α-pyrone derivative, aggregation-induced emission enhancement, restriction of intramolecular rotation, nanoaggregate
