A novel NaNi0.8Co0.15Al0.05O2 material with a spherical architecture and layered monoclinic phase structure was prepared, which delivers remarkable capacity retention of 86.7% at 1C after 200 cycles.

Aiming at tuning the adsorption and fluorescence properties of targeted porous organic polymer, four new aminal-linked porous organic polymers (NAPOPs) were synthesized through the reaction of 1,4-Bis(4,6-diamino-s-triazin-2-yl) benzene (BATB) with four kinds of aldehydes substituted with different N-heterocyclic groups. Among the polymers, NAPOP-3 decorated with 5-phenyl-tetrazole group shows the largest CO 2 adsorption capacity (2.52 mmol g 21 at 273 K and 100 kPa) because of its relative large surface area, while NAPOP-1 decorated with piperazine groups shows relative large CO 2 /N 2 adsorption selectivity (77 at 273 K and 100 kPa), attributable to its large CO 2 adsorption heats and cabined pore (<4 Å ). Meanwhile, NAPOP-1 and 23 exhibit high adsorption rate toward iodine with a high capacity (>240 wt %). In addition, different luminescence emissions were also observed for NAPOPs, indicating different intramolecular charger transfer occurred inside polymer networks.
