SYNTHESES AND CHARACTERISATION OF DIUREA MOLECULAR TWEESORS FOR THE RECOGNITION OF ANION
Two novel urea anion receptors (11) and (12) were synthesized from building block 3,3' methylene diamine and was characterized via the techniques of ¹H NMR, 13CNMR, DEPT- 135 ¹H-¹H COSY, HMQC and HMBC spectroscopy. The ¹H NMR profile of both compounds reveals diagnostic peaks. For compound (11)...
