The cis- and trans-configurational isomers of 3 are designed and investigated as chemodosimeters for CN(-) ions for the first time. The cis-3 reveals a NIR absorbance at 717 nm (vs. trans-3, 620 nm), and such a configurational difference can be attributed to the acidity as well as position of the binding site (CH group). A probable sensing mechanism involving cyanide-driven carbanion electron-transfer
                                    3的顺式和反式构型异构体被设计并首次用作CN(-)离子的
化学计量器。cis-3在717 nm(vs. trans-3,620 nm)处显示NIR吸光度,这种构型差异可归因于酸度以及结合位点(CH基团)的位置。提出了一种可能的检测机制,涉及
