A new
cadmium/6-aminonicotinate-based coordination polymer (CP) with an
unprecedented multicolored and long-lasting emission is reported.
This material shows a blue fluorescence which rapidly turns to green
persistent phosphorescence with a lifetime of nearly 1 s. Time-dependent
density functional theory calculations revealed that electronic transitions
arising from both first excited singlet and triplet states involving
ligand-centered and ligand-to-metal charge-transfer mechanisms are
responsible for such behavior.
