resumo
Phenyl-1,3-diacetate (1,3-PDAt) bridging Cd(II)-based 1D coordination polymer {[Cd(1,3-PDAt)(phen)]& sdot;(MeOH)& sdot;(H2O)(0.5)}(n), (CP) where 1,10-phenanthroline (phen) serves as chelating ligand has been structurally confirmed by Single Crystal X-Ray Diffraction measurements along with other spectral data. The thermal treatment releases MeOH at similar to 90 degrees C and the final product ends at CdO. The Tauc's plot evaluates the band gap, 3.87 eV (calculated value, 3.76 eV) using absorption spectral data which marks the semiconducting nature of the material. This has motivated us to fabricate Schottky Diode device and the measured conductance is 8.87 x 10(-6) S/m in the dark. Interestingly, 1D CP shows selective and specific sorption of Bromocresol Green (BG) out of four common dyes (Methylene blue, Methyl orange, Rhodamine B, and Bromocresol Green (BG)). Besides, the sorbed BG in the CP is leached out on treating with water and the CP has been re-used for further sorption studies. Thus, the CP is economically recycled which is the first principle of Sustainable Development Goals.
