Endowing organic dyes with desired emissive behaviors in diverse states is of great importance for broad practical applications, but it remains a huge challenge. In this study, based on the incorporation of tetraphenylethylene (TPE) into squaraine dyes, we successfully synthesized 2TPE-SQ and TPE-SQ and both exhibited dual state emission with emission efficiencies (ΦPL) up to 0.33 and 0.75, respectively. The intense emission in the crystalline state can be ascribed to highly restricted π-π stacking, while the different degrees of intramolecular phenyl motions in 2TPE-SQ and TPE-SQ result in weak and moderate emissions in solution. Combining density functional theory (DFT) calculations, local excited (LE)/twisted intramolecular charge transfer (TICT) and excited-state intramolecular proton transfer (ESIPT) mechanisms were proposed and accounted well for their very different emission wavelengths in solution and crystalline state, respectively. Besides, other emission behaviors such as aggregation-caused quenching (ACQ), crystalline-induced emission enhancement (CIEE) and thermo-/mechanochromism of these two derivatives were verified in detail, and all these results would bring a new insight into the investigation of organic luminogens in solution and solid state.

Fabrication of hybrid membranes composed of porous materials embedded in polymer matrices is a subject of topical interest. Herein, we introduce a new class of hybrid membranes: hyper-cross-linked metal-organic polyhedra (HCMOPs). These membranes are based upon soluble MOPs that can serve as high-connectivity nodes in hyper-cross-linked polymer networks. HCMOPs spontaneously form macro-scale, defect-free, freestanding membranes, and, thanks to the covalent cross-linking of MOPs, the resulting membranes possess multiple functionalities: strong water permeability; self-healing ability; antimicrobial activity; and better separation and mechanical performance than pristine polyimine membranes. This study introduces a new concept for the design and fabrication of multifunctional membranes and also broadens the applications of MOPs.

The Td point group symmetry of rare earth (RE3+) metal clusters RE4(μ3-OH)4(COO)62+ makes them attractive building blocks for creating metal-organic frameworks (MOFs) with controllable topologies. Herein, we describe the design and synthesis of a series of isoreticular MOFs featuring pcu topology [MOF-1114(RE) and MOF-1115(RE)] with variable rare earth metal ions (RE3+ = Y3+, Sm3+, Eu3+, Gd3+, Tb3+, Dy3+, Ho3+, Er3+, Tm3+, Yb3+) and linear amino-functionalized dicarboxylate linkers of different lengths. In total, we report 22 MOFs that vary in both composition and structure yet share the same RE4(μ3-OH)4 cluster motif. We demonstrate that these pcu MOFs are cationic and that anion exchange can be used to affect the MOF properties. We also investigate the luminescence properties of a representative member of this MOF series [MOF-1114(Yb)] that exhibits near-infrared emission. We show that the excitation energy for Yb3+ sensitization can be carefully adjusted to lower energy via covalent postsynthetic modification at the amino group sites within the MOF.
