Abstract
The reaction of Cul with the highly flexible dithioether ligand p-TolS(CH2)(8)STol-p affords both in MeCN or in EtCN the 2D coordination polymers [Cu(8)l(8){p-TolS(CH2)(8)STol-p}(3)(solvent)(2)](n) (1 center dot MeCN and 1 center dot EtCN) containing octanuclear Cu(8)l(8) clusters as connection nodes. In contrast, treatment of Cul with p-tBuC(6)H(4)S(CH2)(8)SC(6)H(4)But-p in EtCN solution leads to the formation of the luminescent 1D CP [Cu(4)l(4){t-BuC6H4S(CH2)(8)SC6H4-tBu)(2) (2 center dot EtCN)(n) incorporating Cu-4([mu(3)-l)(4) clusters of the closed cubane type as secondary building units (SBUs). The 2D coordination polymers 1 center dot MeCN and 1 center dot EtCN demonstrate the ability to lose their solvent crystallisation molecules under vacuum and readsorb the same or a new one using vapor as monitored by powder X-ray diffraction, thermogravimetric, IR, chromaticity, emission spectra and emission lifetime measurements. Conversely, the 1D material 2 center dot EtCN does not readsorb EtCN, likely due to the collapse of the macrocycles formed by the metal cluster nodes and flexible long chained ArSC8SAr ligands but absorbs a smaller substrate such as CO2.
