These novel probes exploited tetraphenylethene （TPE） as fluorophore and macrocycle-polyamine （including 1,4,7,10-tetraazacyclo- dodecane and 1,4,7-triazacyclononane） Zn（ll） complexes as binding group. These ＂OFF-ON＂ type probes exhibited promising selectivity and sensitivity to PPi and ATP via a restriction ofintramolecular rotation （RIR） mechanism. The detection limit for PPi was found within nmol/L range.展开更多
