Title: A Cobalt Supramolecular Triple-Stranded Helicate-based DiscreteMolecular Cage

Description: This research was supported by the National Research Foundation of Korea(NRF) grant funded by the Korea government (MSIP) (NRF-2015R1A4A1041631and NRF-2016R1A2B4009281). Experiments at PLS-II were supported in partby MSIP and POSTECH (2016-1st-2D-002 and 2016-2nd-2D-008). Magneticmeasurements were performed using facilities at IBS Center forCorrelated Electron Systems, Seoul National University.

abstract: We report a strategy to achieve a discrete cage molecule featuring a high level of structural hierarchy through a multiple-assembly process. A cobalt (Co) supramolecular triple-stranded helicate (Co-TSH)based discrete molecular cage (1) is successfully synthesized and fully characterized. The solid-state structure of 1 shows that it is composed of six triple-stranded helicates interconnected by four linking cobalt species. This is an unusual example of a highly symmetric cage architecture resulting from the coordination-driven assembly of metallosupramolecular modules. The molecular cage 1 shows much higher CO2 uptake properties and selectivity compared with the separate supramolecular modules (Co-TSH, complex 2) and other molecular platforms.
