Chemodosimetric cyanide sensing in a 5,15-porphodimethene Pd(ii) complex

Abstract

The Pd(II) complex of 5,15-porphodimethene is shown as a chemodosimetric sensor where it selectively senses cyanide ions, monitored through electronic spectral analysis and identified by the naked eye. The possible binding mechanism is also proposed based on the ¹H NMR analyses. Two polymorphs of the mentioned complex are obtained by using different polar solvents and further confirmed by single crystal X-ray analyses.
