disaggregation and complete fluorescence quenching. The in situ generated BTPPA-Cu2+ complex can further act as a chemosensing ensemble for highly selectiverecognition of pyrophosphate (PPi) via Cu2+ displacement approach, which results in re-aggregation of BTPPA and fluorescence recovery. Thus relay recognition of Cu2+ and PPi has been achieved with ‘on-off-on’ emission changes through aggregation-switching
