Microwave-Assisted Selective Synthesis of Mono- and Bistriazines with π-Conjugated Spacers and Study of the Optoelectronic Properties

Microwave-Assisted Synthesis of Bidentate Chiral Unsymmetrical Urea Derivatives of P-tert-butylcalix[4]Arene and their Anion Recognition Properties

Four new derivatives of p-t-butylcalix[4]arene containing two (1,3-distal) chiral unsymmetrical urea moieties at the lower rim were synthesised in four steps. Their anion recognition properties toward MeCO2−, H2PO4−, NO3−, I−, Br−, Cl− were assessed by UV-Vis titration spectroscopy. All the receptors showed the strongest recognition ability for MeCO2−, one of them having an association constant of 3139 M-1. 1H NMR studies of this receptor complex confirmed its tight binding of MeCO2−.

Synthesis and photophysical, electrochemical, antibacterial, and DNA binding studies of triazinocalix[2]arenes

The synthesized calix[2]arene[2]triazine derivatives bind effectively to DNA and exhibit efficient antibacterial activity against B. cereus, S. aureus and E. coli bacteria as supported by docking studies.
