The target compound(C58H74N6O10) has been structurally determined by singlecrystal X-ray diffraction. The crystal is in the monoclinic system, space group C2/c, with a = 22.08(3), b = 12.628(19), c = 21.73(3) , β = 106.78(3)°, C58H74N6O10, Mr = 1015.23, Dc = 1.16239 g/cm3, V = 5801(14)3, Z = 4, F(000) = 2176, μ(MoKa) = 0.080 mm-1, T = 293(2) K, 5107 independent reflections with 3125 observed ones(I > 2σ(I)), R = 0.0768 and w R = 0.2305 with GOF = 1.025(R = 0.1129 and w R = 0.2674 for all data). The calixarene moiety maintains the symmetric cone conformation through intramolecular O–H···O and N–H···O hydrogen bonds. The thermal analysis showed that the decomposition mechanism of compound 3 is complex. Fluorescence spectra of 3 exhibited an emission band at 423 nm when excited with 360 nm radiation at room temperature in DMF.
