A new heterocyclic calixarenes and their derivatives and the calyx(n)arenes comprising heterocyclyl calyx(n)arenes wherein n represents phenolic units and is equal to 4, 6, 8 and 10. The arenes so obtained are characterised by IR spectra at 3059(bs), 2935(sh), 1670.6(s), 1595.56(s), 1479, 1449.8, 1429(w), 1212(s), 1008.75(s), 765.83(s), 718.67(m), 696(s), 643.7(m) cm-1 wherein n is 8. The typical 1H NMR spectra of heterocyclyl calix[n]arenes, wherein "n" is equal to 8, when taken in deurated chloform solvent shows peaks at 7.99-7.96(d, ArH), 7.69-7.64(m, Arh), 3.93(s, OCH3), 4.21(bs, ArCH2Ar).
