TL;DR: In this article, tetrakis(4-pyridyloxymethylene)methane (TPOM) with deprotonated 1,4-benzenedicarboxylate (H2BDc) or 5-hydroxyisophthalic acid (5-OH-H2bdc) were characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction.

Abstract: Solvothermal reactions of tetrakis(4-pyridyloxymethylene)methane (TPOM) with deprotonated 1,4-benzenedicarboxylate (H2bdc) or 5-hydroxyisophthalic acid (5-OH-H2bdc) in the presence of nitrates of cadmium, zinc, and cobalt in H2O or H2O/DMF produced five new complexes, namely, {[Cd2(TPOM)(bdc)2]·(H2O)5(DMF)}n (1), {[Zn2(TPOM)(bdc)2]·(H2O)4}n (2), {[Zn2(TPOM)(bdc)2]·(H2O)}n (3), {[Co2(TPOM)(5-OH-bdc)2(H2O)2]·(H2O)5}n (4), and {[Cd2(TPOM)(5-OH-bdc)2]·(H2O)2}n (5). These complexes were characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Complex 1 reveals a 2-fold interpenetrating three-dimensional (3D) framework with pcu topology constructed from binuclear Cd clusters and TPOM ligands. In addition, the experiment of single-crystal-to-single-crystal (SC-SC) structural transformations upon guest exchange was tested. Zn complexes 2 and 3 possess different 3D frameworks and are prepared from TPOM and H2bdc under different reaction conditions. In complexes 4 and 5, TPOM and ...

TL;DR: A MOF that consists of glycyl–serine dipeptides coordinated to metal centres, and has a structure that evolves from a solvated porous state to a desolvated non-porous state as a result of ordered cooperative, displacive and conformational changes of the peptide.

TL;DR: This work has shown that highly porous frameworks held together by strong metal–oxygen–carbon bonds and with exceptionally large surface area and capacity for gas storage have been prepared and their pore metrics systematically varied and functionalized.
Luminescent Metal–Organic Frameworks
TL;DR: This critical review discusses the origins of MOF luminosity, which include the linker, the coordinated metal ions, antenna effects, excimer and exciplex formation, and guest molecules.

A Homochiral Porous Metal−Organic Framework for Highly Enantioselective Heterogeneous Asymmetric Catalysis
TL;DR: Control experiments with dendritic aromatic aldehydes of different sizes indicate that the heterogeneous asymmetric catalyst derived from 1 is both highly active and enantioselective as a result of the creation of readily accessible, uniform active catalyst sites inside the porous MOF.
