摘要：

Novel indeno[1,2-b] benzo[4,5-e] pyran-11-one-type fluorophores exhibiting intense solid-state fluorescence were conveniently synthesized and the relation between their solid-state photophysical properties and the X-ray crystal structures were investigated, which demonstrates that non-planar structures with sterical hindered substituents prevent the fluorophores from forming short pi - pi contacts causing fluorescence quenching in the solid state.
