Key Points

To elucidate noncovalent anion–π interactions in a naphthalenediimide-based palladium(II) coordination polymer and evaluate its utility for fluoride ion sensing.
Synthesized a zigzag coordination polymer composed of palladium(II) ions and linear N,N′-di(4-pyridyl)naphthalenediimide (DPNDI) ligands.
Characterized structural noncovalent interactions between anions and ligands using single-crystal X-ray crystallography.
Assessed ligand π-acidity and monitored fluoride-induced electron transfer via electrochemical and colorimetric analyses.
X-ray crystallographic analysis provided direct structural evidence of noncovalent anion–π interactions between triflate anions and DPNDI ligands.
Electrochemical measurements revealed that DPNDI/triflate interactions decrease π-acidity, whereas palladium(II) coordination enhances DPNDI π-acidity.
The [Pd(II)/DPNDI]n coordination polymer preserved fluoride-induced electron transfer, enabling visual colorimetric detection of fluoride.
