“…Based on these research backgrounds, ( R )‐4‐(1‐carboxyethoxy) benzoic acid (( R )‐H 2 CBA) and ( S )‐4‐(1‐carboxyethoxy) benzoic acid (( S )‐H 2 CBA) were synthesized by using lactic acid as chiral moiety to attach 4‐hydroxybenzoic acid [32] . As expected, ( R )‐H 2 CBA and ( S )‐H 2 CBA as chiral linkers have provided a convenient path to synthesize chiral MOFs [33–34] . Herein, we continued to choose ( R )‐H 2 CBA and ( S )‐H 2 CBA to assemble with Co(II) ions to obtain chiral MOFs in the existence of 1,3‐di(pyridin‐4‐yl)propane (1,3‐DPP) as second linker.…”

A pair of new chiral Co(II) metal‐organic frameworks based on semi‐rigid lactic acid derivatives, namely, {[Co((R)‐CBA)(1,3‐DPP)(H2O)0.5] ⋅ H2O}n(1‐R) and {[Co((R)‐CBA)(1,3‐DPP)(H2O)0.5] ⋅ H2O}n (1‐S) (H2CBA=4‐(1‐carboxyethoxy) benzoic acid, 1,3‐DPP=1,3‐di(pyridin‐4‐yl)propane) were synthesized under hydrothermal conditions. The structures of complexes 1‐R and 1‐S were determined by single crystal X‐ray crystallography, revealing dinuclear cobalt units are connected through (R)‐ or (S)‐CBA2− anions that lead to the formation of enantiomeric helical chains. Helical chains are further linked together to build 3D Co‐(R)‐CBA (Co‐(S)‐CBA) framework in 1‐R(1‐S). Furthermore, more large helical chains are formed by Co(II) centers and 1,3‐DPP ligands in 1‐R and 1‐S. As a result, 1,3‐DPP ligands are introduced into complexes to stabilize the CBA−Co frameworks to obtain a four‐connected dia net. Apart from delicate structure, the UV‐vis sorption spectrum, Mott‐Schottky measurements and electrochemical impedance spectroscopy (EIS) demonstrated that complex 1‐R is a typical n‐type semiconductor with low resistance in charge transportation. Photo‐catalytic test result confirmed the complex 1‐R has catalytic activity for the degradation of RhB.
