Abstract

Abstract : Due to the periodically physical/chemical environment and high‐efficient confinement effect of the metal‐organic framework (MOF) only possessing 1D channels, the authors realize periodically and highly aligned dye molecule integration within the MOF hybrid material ZJU‐68⊃DMASM. Such molecule integration can provide an opportunity to directly determine 4‐[ p ‐(dimethylamino)styryl]‐1‐methylpyridinium (DMASM) molecules in the MOF channels by electron density mapping using X‐ray diffraction data. Furthermore, combining the anisotropic emission property of such molecule integration and the perfect crystal morphology of ZJU‐68 serving as the natural resonant cavity, the authors obtain a single‐mode linearly polarized laser excited by light ranging from visible to near‐infrared. Abstract : A periodically aligned laser dye molecules integrated within the metal‐organic framework (MOF) ZJU‐68 exhibit σ‐polarized single‐mode lasing. Such molecule integration provides an opportunity to directly determine dye molecules in the MOF channels by electron density mapping via X‐ray diffraction data and exhibits significant anisotropic properties of light absorption and emission.
