Optical Properties and Applications of Crystalline Materials

Recent years have witnessed the prosperous developments of crystalline materials based on diverse organic/inorganic small molecules, metal organic frameworks (MOFs), covalent (COFs), etc. Crystalline are highly attractive for their ordered molecular and supramolecular architectures, allowing rational design with brilliant optical properties advanced photonic applications. In particular, often feature well-defined morphologies in wavelength subwavelength scales, therefore ideal platforms realization many functionalities such as waveguiding, lasing, logics. recognition importance this field, we gladly taken opportunity to serve Guest Editors organize themed special issue, aim highlight state art area This consisting 14 reviews 6 research papers, covers a broad spectrum recent advances MOFs, COFs, perovskites, microporous zeolites, molecules. It encompasses some important achievements, efforts practices well-established applications including light emitting diodes (LEDs), waveguides, sensing, nonlinear optics (NLO), well emerging technologies terahertz (THz) generation detection. MOFs assembled by coordination interactions between metal-containing nodes linkers. Luminescent diversified devisable pore structures affluent luminescence, provide great potential development novel phosphors. review article, Prof. Guodong Qian co-workers focus phosphor-converted white LEDs MOF matrixes doped luminescent lanthanide ions, ligands, and/or encapsulated guest species dyes, complexes, quantum dots (adom.202001817). terms host–guest Xian-He Bu comprehensive construction strategies particles hybridized (adom.202100283). Similar encapsulation strategy can be applied other porous materials.
