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 (1)H NMR analyses. Two polymorphs of the mentioned complex are obtained by using different polar solvents and further confirmed by single crystal X-ray analyses.
ABSTRACT
Synthesis, spectral and structural characterization of a pyrroloindolizine derivative having structural similarity with calix[2]pyrrole is described. Here, two pyrrole rings are connected with two meso-carbon atoms having an N,α-linkage and an α,ß-linkage to afford the smallest analogue in the calixpyrrole family. Detailed NMR spectroscopic studies along with single crystal X-ray analysis confirm the assigned structure of the molecule.
