A barium(II) metal‐organic framework (MOF) based on a predesigned amino‐functionalized ligand, namely [Ba2(L)(DMF)(H2O)(NO3)1/3]⋅DMF⋅EtOH⋅2 H2O (UPC‐33) [H3L=4,4′‐((2‐amino‐5‐carboxy‐1,3‐phenylene)bis(ethyne‐2,1‐diyl))dibenzoic acid] has been synthesized. UPC‐33 is a 3‐dimensional 3,18‐connected network with fcu topology with a rare twelve‐nuclear Ba12(COO)18(NO3)2cluster. UPC‐33 shows permanent porosity
industrial applications. However, challenges exist in the pore environment engineering of porous materials to recognize two molecules due to their similar molecular sizes and physical properties. Herein, we report a strategy to optimize pore environments of multivariate metal-organic frameworks (MOFs) for efficient C2H2/CO2 separation by tuningmetal components, functionalized linkers and terminal ligands

hexafluorophosphate is prepared and used as a water-soluble ligand in the Suzuki-Miyaura reaction. This ligand and palladium chloride generates a new active catalyst for the Suzuki coupling reaction between aryl iodides or bromides with arylboronicacids in neat water. This catalyst can be recycled and reused for the coupling reaction of 4-bromobenzonitrile with phenylboronic acid for at least six runs with

Disclosed herein are am bipolar host compounds represented by formula (I), wherein: a) R4 is an optionally substituted aryl or an optionally substituted heteroaryl group; b) n is at least 2; e) for each (ii) at least one of R1, R2 and R3 is independently an optionally substituted carbazole group, and the remaining of R1, R2 and R3 are independently selected from hydrogen, halogen and a C1-20 organic group: and d ) Y is selected from (III), wherein R5 is an.optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted alkyl group or an optionally substituted heteroalkyl group, and wherein R6 is hydrogen,, an optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted alkyl -group or an optionally substituted heteroalky! group. The compounds can be used in OLED devices and are ambipolar. The OLED devices can show high efficiency and high luminance.
a yellow-emitting supramolecularpolymer thin film with high quantum yield (0.22), a white-light-emitting LED was fabricated by painting the thin film onto an ultraviolet LED. This study presents an efficient approach for tuning the properties of fluorescent supramolecularpolymers and the potential of the metallacycle-cored supramolecularpolymers as a platform for the fabrication of light-emitting
