A novel three-dimensional metal-organic framework with primitive cubic (pcu) topology exhibits interesting tunable photoluminescent emission based on the variation of excitation light at room temperature. By judicious choice of two different conjugated organic linkers incorporating in a certain framework, the contributions of distinct emission bands may be finely controlled. This work may provide a new route to explore functional luminescent materials with tunable photoluminescence. Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
