Fluorescent recognition of Fe³⁺ and Fe³⁺-functionalized composite materials for enhancing photocatalytic activities of Co^II complexes

Abstract

Six new Co^II complexes (<bold>1–6</bold>) based on a bi-methylene-bridged bis-pyridyl-bis-amide have been synthesized. <bold>5</bold> and <bold>6</bold> exhibit photoluminescent sensing selectivity for Fe³⁺, and Fe³⁺-functionalized composites Fe³⁺@<bold>5</bold> and Fe³⁺@<bold>6</bold> show photocatalytic properties for the degradation of organic dyes.
