the compounds were screened for preliminary antitubercular activity against Mycobacterium phlei and Mycobacteriumtuberculosis H37RV. Among all the target compounds, the compound possessing chlorine (7k, MIC 1.56 μg/mL) and bromine (7m, MIC 1.56 μg/mL) on 6th position of benzofuran showed highest activity against Mycobacterium phlei. Whereas, bromine on either 5th position (7l, MIC 3.125 μg/mL) or 6th

Optoelectronic properties have been carried out by combination of DFT calculations and moleculardynamics (MD) simulations, in order to assess the potential of this structure for applications in organic electronics. Further, the study encompassed calculations of reorganization energies for holes and electrons and charge transfer rates. DFT calculations have been also used in order to identify locations
