New Zr(IV)- and Hf(IV)-based metal-organic framework photocatalysts, termed VNU-1 and VNU-2 (where VNU = Vietnam National University), were synthesized and their resulting structures fully characterized. By employing a highly π-conjugated linker, namely 1,4-bis(2-[4-carboxyphenyl]ethynyl)benzene, the optical absorption properties were effectively red-shifted

A new conjugated polymer possessing calix[4]arene-oxacyclophane units wired-in-series by phenyleneethynylene linkers was synthesized by a Sonogashira-Hagihara cross-coupling method in high yield. The polymer was structurally characterized by FTIR and 1H/13C/HSQC NMR techniques, and its average Mn (38.5 kDa) retrieved from GPC
