Abstract: A novel calix[4]arene derivative (2), 5,11,17, 23-tetra-tert-butyl--25, 26-dihydroxy-27, 28-[bis(p-toluenesulfonylaminoethoxy)]calix [4]arene was synthesized in a 90% yield by the reaction of 5,11, 17, 23-tetra-tert-butyl-25, 26-dihydroxy-27, 28- [bis (β-aminoethoxy)]-calix [4] arene (1) and p-tolue-nesulfonyl chloride in dry CH2C12 in the presence of NEt3.compound 2 crystallizes in triclinic space group P1, with a = 1.20444(11) nm, b = 1.61735(14) nm, c = 1.77316(15) nm, a=80.050(2)°, β=76.644(2) °,γ = 82.084(2) °, V = 3.2929(5) nm3, Dc=1.135 g/cm3, Z=2, R = 0.0683.Theresult shows the flatted cone conformation with the distorted sulfonamido substituents attached to the low-er rim of compound 2 resulted from the dipole-dipole repulsive interaction.The structure of 2-acetonitrilecomplex shows that the acetonitrile lies on the pseudo crystallgraphic fourfold axis with the nitrogen atomdirecting exo and the methyl pointing inside the intramolecular cavity, which is attributed to the specificCH-π interaction between the acetonitrile CH3 group and the aromatic nuclei of host 2.
