We achieved a dense IO hybrid superhydrophobic porous coordination polymer (PCP), [Pb(H-BTMB)(DMF)] (1), by solvothermal methods. The single-crystal XRD structure of 1 indicated that it has a three-dimensional M-L-M framework with one-dimensional M-O-M connectivity leading to an IO network. The new PCP obtained exhibited open metal sites (OMSs) by losing a coordinated DMF molecule. The degassed phase displayed selective adsorption of CO gas over N, CH, and CH gases. Additionally, it has a superhydrophobic surface with a contact angle of 156.4° at room temperature and it is stable even at 90 °C, displaying a contact angle of 135.3°.

Synthesis, characterization, and antibacterial active studies of 12 coumarin derivatives were described in this study. Synthesis was achieved by the reaction of 4‐carbonyl chloride with 1,2‐dichloroethane as a solvent, in moderate to good yields. The structures of all the newly synthesized molecules were assigned by spectral data and elemental analysis. The synthesized compounds were screened for their antibacterial activities strains using paper disc method.
