Abstract
A 2D coordination polymer, [Zn2(BDC)4(QPR)2(H2O)]n (Zn(II)‐CP) (BDC2− = 1,4‐benzenedicarboxylato; QPR = 7‐[(pyridin‐4‐ylmethylene)‐amino]‐chromen‐2‐one), is presumably the first reported on coumarinyl‐pyridyl framework with terephthalato linker. The optical band gap, 2.91 eV, is obtained from the Tauc's plot that insists to fabricate an optically stimulated semiconducting device, and the electrical conductivity exhibited (Λ) is 8.07 × 10−3 S m−1 (dark) and 9.26 × 10−3 S m−1 (light). The cytotoxicity in the selected human cancer cell lines like HeLa, MDA‐MB 231, and HepG2 cells in relative to the normal kidney epithelial (NKE) cell line has been examined, and its efficacy is observed highest in inhibiting proliferation of HeLa cells (IC50, 21.02) compared with other cancer cells (IC50: 42.22 [HepG2] and 46.37 [MDA‐MB 231]). Further, the Zn(II)‐CP possess intracellular reactive oxygen species (ROS) generation and caspase‐3/7 activation leading to G2/M cell cycle arrest and apoptotic cell death in HeLa cell line. This novel coumarinyl‐pyridyl ligand appended Zn(II)‐CP has been employed for the fabrication of semiconducting device, which is quite impressive in view of existing energy crisis civilization; in addition, the compound has excellent bio‐activity.
