| Abstract: | Utilizing semirigid lactic acid derivatives (R)‐H2CBA and (S)‐H2CBA as chiral ligands, two pair of homochiral coordination polymers formulated as Zn((R)‐CBA)(1,4‐DIB)] · H2O ( 1 ‐ D ), Zn((S)‐CBA)(1,4‐DIB)] · H2O ( 1 ‐ L ), Co((R)‐CBA)(1,4‐DIB)] · H2O ( 2 ‐ D ) and Co((S)‐CBA)(1,4‐DIB)] · H2O ( 2 ‐ L ) were prepared under solvothermal reaction condition. Single X‐ray diffraction study reveals that all the complexes are comprised of three kinds of helical chains, which are constructed by corresponding metal ions, CBA2– ligands, and/or 1,4‐DIB ligands. Moreover, some physical characteristics, such as PXRD, thermal stabilities, solid‐state circular dichroism (CD), luminescent and magnetic properties are also investigated. |
