Facile synthesis of a micro-scale MOF host–guest with long-lasting phosphorescence and enhanced optoelectronic performance

Abstract

Micro-scale MOFs with a persistent phosphorescence lifetime of 900 ms can be facilely synthesized by a fast precipitation process in aqueous solution. The in situ encapsulation of a dye into the MOF matrix can expressly tune the phosphorescence color from green to a rare example of red emission with a lifetime of 450 ms, highly enhancing the photoelectrocatalytic water splitting.
