A new azopyrrole compound, 1, has been synthesized and characterized. The crystal of 1 is of monoclinic system, space group P21/c with a = 8.7167(9), b = 17.5929(19), c = 12.8096(15) ?, β = 97.565(2)o, V = 1947.3(4) ?3, Z = 4, C_(20)H_(26)N_4O_2, Mr = 354.45, Dc = 1.209 g/cm~3, F(000) = 760 and μ(Mo Kα) = 0.080 mm~(-1). In the crystal, 1 binds one methanol molecule through N–H…O, O–H…O and O–H…π interactions. UV-Vis titration and 1H NMR titration studies reveal that compound 1 can selectively detect fluoride ion in the DMSO solution.
