- Abstract
A pair of enantiomers of three‐dimensional (3D) chiral coordination polymers (CCPs) were successfully constructed by using achiral components 4,2′:6′,4′′‐terpyridyl precursors and Cu2+ through spontaneous resolution (1 a). By utilising feeding controlled chiral‐templated induction and chiral auxiliary behaviour of optically pure camphor sulfonate (CSA), the enantioenriched (1 b‐P and 1 b‐M) and CSA captured (1 c‐P and 1 c‐M) CCPs were successfully synthesised, respectively. The chiral information of the corresponding products was confirmed by X‐ray single crystal diffraction and solid‐state CD spectra. Meanwhile, the formation processes of 1 b‐P and 1 b‐M were monitored through solution CD spectra, UV/Vis spectra and ESI‐TOF MS. Based on these results, a reasonable chiral‐templated induction mechanism of forming 1 b‐P and 1 b‐M was proposed.
