摘要

•A novel baso-chromic spiropyrrolizine displaying isomerization have been designed.•The baso-cyclization is induced by organic/inorgainc base, affording the ring-closed isomer.•It induces dramatic changes in both absorption and emission.•The formation of SP was demonstrated by 1H NMR and DFT calculation.
