Abstract

Abstract : We prepared an organic molecular glass material with a large central planar π unit, which showed a unique dielectric anomaly and isolated fluorescence properties. Abstract : We prepared octylbenzoate-substituted [12]DBA (C8[12]DBA ) as an organic molecular glass material. Even with a central large, planar π unit of [12]DBA, which is generally advantageous for the formation of a crystalline/liquid crystalline state, this compound formed a thermally stable glass state due to its small intermolecular π contact between [12]DBA units and twisted geometries around the terminal benzoate units. C8[12]DBA showed a unique dielectric anomaly and isolated fluorescence properties in the glass state.
