Mechanochemical synthesis of a processable halide perovskite quantum dot-MOF composite by post-synthetic metalation

Perovskite quantum dots (PQDs) are some of the most sought after materials for optoelectronic and photovoltaic applications. We report the mechanochemical, solvent-free synthesis of a PQD?MOF composite using a post-synthetically PbII metalated

Versatile Assembly of Metal-Coordinated Calix[4]resorcinarene Cavitands and Cages through Ancillary Linker Tuning

We propose a design strategy for assembly of metal-coordinated calix[4]resorcinarene cavitands and cages by tuning of the ancillary linkers. Assembly of newly functionalized cavitand with angular isophthalic acid analogs affords three intriguing metal-coordinated cavitands with deep cavities, 1a-1c. Further, by mediating appropriate spacers between two isophthalic acids, two bowl-shaped cavitands are successfully joined together to produce three elegant coordination cages with tunable sizes and shapes, 2a-2c. The cavitand and cage crystals possess considerable amount of accessible porosities, as clearly established by gas adsorption measurements. Remarkably, 1a-1c also exhibit high structural flexibilities, reversibly transforming between the open-pore and the narrow-pore structures, upon removal and sorption of guest molecules, as evidenced by diffraction and gas adsorption measurements. By combining experimental studies with density functional theory (DFT) calculations, we thoroughly elucidated the mechanism of the structural transformations in response to external stimuli in this new class of flexible porous solids.

Synthesis, Characterization, and X-ray Structure of the Ruthenium "Picnic-Basket" Porphyrins

The synthesis and characterization of a new class of sterically protected porphyrins, the "picnic-basket" porphyrins, are presented.These tetraarylporphyrins, which were prepared as cytochrome P-450 active-site analogues, bear a rigid superstucture on one face of the porphyrin macrocycle.The cavity defined by the appended superstructure may be readily varied in size, chirality, and functionality.In addition, the synthesis and characterization, including an X-ray structure, of several ruthenium picnic-basket porphyrin carbonyl complexes are reported.The regiochemistry of axial ligation in these ruthenium derivatives has been determined by 1H NMR spectroscopy.
