Order from Chaos: Self-Assembly of Nanoprism from a Mixture of Tetratopic Terpyridine-Porphyrin Conformers

Porphyrins have been widely used in the self-assembly of metallo-supramolecules. In this study, we introduced 2,2':6,2"-terpyridine (tpy) into a porphyrin core to synthesize a tetratopic building block with multiple conformers. During the self-assembly with Zn(II), such a mixture of conformers was able to form a discrete nanoprism with all building blocks in one conformation. Detailed characterizations, including NMR, ESI-MS and traveling-wave ion mobility-mass spectrometry (TWIM-MS), all supported the formation of the desired assemblies. AFM and TEM further confirmed the dimensions of assembled nanoprisms. Moreover, the photophysical properties of the ligands and complexes were noticeably different depending upon size and metal ion center.

Dehydrogenative lactonization of diols with a platinum-loaded titanium oxide photocatalyst

A new catalytic route for the lactonization of diols was developed by using a metal-loaded TiO2 photocatalyst. In particular, Pt-loaded rutile TiO2 exhibited a high photocatalytic activity with high selectivity. In addition, it was found that a heterogeneous acid catalyst can accelerate this photocatalytic lactonization.

Organocatalytic enantioselective synthesis of phthalans via Wittig/oxa-Michael cascade reaction

An enantioselective synthetic method for 1-substituted phthalans has been developed. The organocatalytic reaction between 1,3-dihydro-2-benzofuran-1-ols and Wittig reagents using cinchona squaramide-based organocatalyst proceeded with sequential Wittig reaction followed by an enantioselective intramolecular oxa-Michael reaction, yielding enantioenriched phthalans with moderate to good enantioselectivities.
