Construction of three-dimensional polymeric D-histidine based metal-organic framework (MOF) for selective sorption of CO2 and copper ion sensing applications

This report investigates infinite three-dimensional D-histidine based bio-metal organic framework single crystal (DHTZn) for versatile applications. Sorption analysis at different temperatures indicates DHTZn crystal has excellent adsorption capacity for CO2 (462 cm(3) g(-1) at 273 K and 379 cm(3) g(-1) at 298 K) when compared to N2 (230 cm(3) g-1 at 273 K and 188 cm(3) g(-1) at 298 K). The DHTZn was effectively sensing Cu2} ions, KSV value and detection limits are 4.24 x 105 M-1 and 0.0947 x 10- 7 M respectively. Based on the above outcomes, DHTZn crystal might be useful for selective sorption and separation of CO2 with Cu2+} ion sensing.
