pH-Regulated structural evolution enables excitation-dependent tunable and quasi-white-light emission in tetrazole-based d 10 coordination polymers

Puntos clave

• The study aims to explore how pH and structural evolution influence photoluminescence in tetrazole-based coordination polymers.
• Investigated three tetrazole-based coordination compounds with different dimensionalities.
• Analyzed the relationship between coordination geometry and π–π interactions and their effects on photoluminescence.
• Supported findings with crystal structures and density of states (DOS) calculations.
• Demonstrated excitation-dependent multicenter photoluminescence in all three compounds.
• Showed structural changes influenced emission properties, resulting in quasi-white-light emission.
• Established a mechanism for tunable photoluminescence based on coordination geometry.
