Synthesis of Rigid Rod, Trigonal, and Tetrahedral Nucleobase-Terminated Molecules

An efficient fragment splicing method for the construction of multiple nucleobase-terminated monomers has been developed. Conformationally fixed rod, trigonal planar and tetrahedral thymine and adenine structures were generated in moderate to good yields,

Preparation of a bispyridine based porous organic polymer as a new platform for Cu(ii) catalyst and its use in heterogeneous olefin epoxidation

A new type of bispyridine (bpy) incorporated POP was prepared via a cobalt-catalyzed acetylene trimerization. Subsequent immobilization of CuCl2 gave POP-Cu(ii). This new heterogeneous catalyst displayed outstanding olefin oxidation activity compared to its homogeneous analogue, suggesting that the degradation of the homogeneous catalyst was successfully inhibited by site isolation.

Microporous organic polymers involving thiadiazolopyridine for high and selective uptake of greenhouse gases at low pressure

A new core of [1,2,5]-thiadiazolo-[3,4-c]-pyridine was employed for the fabrication of microporous organic polymers exhibiting a very high CO2 uptake of 5.8 mmol g-1 (25.5 wt%) at 273 K and 1 bar. The presence of CO2-philic active sites and microporosity confer the high uptake and superior selectivity (61) towards CO2 over N2.
