Facile fabrication of photonic MOF films through stepwise deposition on a colloid crystal substrate

Abstract

Based on stepwise deposition of MOF films on a colloid crystal substrate, a strategy for fabricating photonic MOF films was developed. We found that the integration of a photonic structure endows MOF materials with unique optical properties, which can be used as a general and effective transduction scheme for a convenient study of the host-guest chemistry of MOFs.
