Abstract

A luminescent zinc complex has been encapsulated in the ordered, 3.2 nm wide hexagonal channels of a nanoporous MCM-41 host. A marked 19 nm blue-shift of the major absorption band maximum is found for the zinc complex in ethanol solution relative to the complex loaded in MCM-41, which is correlated with an increased band gap in the former. A 17 nm blue-shift of the emission peak is also observed, which is estimated to be related to the decrease of polarity around the zinc ions.
