Structural Study and Fluorescent Property of a Novel Organic Microporous Crystalline Material

A novel microporous organic material [(2-{2-[2-(bis-methoxycarbonylmethylamino) phenoxy] ethoxy}-4-benzimidazole-phenyl) methoxycarbonylmethylamino] acetic acid methyl ester 6 was synthesized and characterized by single crystal X-ray diffraction, Fourier transform infrared spectroscopy (FT-IR), electron spray ionization-mass spectrometry (ESI-HRMS), X-ray powder diffraction (PXRD), H-1 and C-13 NMR. 6 crystallizes in the centrosymmetric monoclinic space group C2/c, with unit cell parameters a = 35.648(3) angstrom, b = 14.3240(12) angstrom, c = 15.3693(13) angstrom, alpha = 90.00, beta = 94.8190(10), gamma = 90.00, V = 7820.16 angstrom(3) and Z = 8 at 296(2) K. As indicated by crystal packing, the molecular conjugation planes arrange along the c axis to form micropores due to the hydrogen bonds. In addition, the fluorescent spectrum and luminescence lifetime were studied for 6.
