We described a serious of zinc complexes that exhibit characteristic fluorescence responses toward pyrophosphate(PPi) and adenosine triphosphate(ATP) in aqueous media. These novel probes exploited tetraphenylethene(TPE) as fluorophore and macrocycle-polyamine(including 1,4,7,10-tetraazacyclododecane and 1,4,7-triazacyclononane) Zn(II) complexes as binding group. These ‘‘OFF–ON’’ type probes exhibited promising selectivity and sensitivity to PPi and ATP via a restriction of intramolecular rotation(RIR) mechanism. The detection limit for PPi was found within nmol/L range.
We described a serious of zinc complexes that exhibit characteristic fluorescence responses toward pyrophosphate (PPi) and adenosine triphosphate (ATP) in aqueous media. These novel probes exploited tetraphenylethene (TPE) as fluorophore and macrocycle-polyamine -tetraazacyclododecane and 1,4,7-triazacyclononane) Zn (II) complexes as binding group. These ’OFF-ON’ ’type- ores revealed promising selectivity and sensitivity to PPi and ATP via a restriction of intramolecular rotation (RIR) mechanism. The detection limit for PPi was found within nmol / L range.

磷杂环丙烷加热裂解可以生成亚膦烯,但是迄今为止通过这种方法合成亚膦烯的例子并不多。在探索磷杂环丙烷配合物热解生成亚膦烯配合物的过程中,发现1-H磷杂环丙烷配合物可以发生异构化生成[(CO)_5W-P-CH_2CH_3]乙基亚膦烯配合物,1-酯基磷杂环丙烷配合物可以裂解生成典型的亚膦烯配合物,1-酰基磷杂环丙烷配合物则发生配合物的脱离,而1-酰基2-苯基磷杂环丙烷可以发生裂解生成酰基亚膦烯配合物,也
