A highly selective iron ions fluorescent probe based on the benz(c)acridine-1,2,3-triazole derivatives was produced by multi-step reactions. 1-(7-Benz[c]acridinyl)-4-(4-methylphenyl)-1,2,3-triazole(4 a), C_(26)H_(18)N...A highly selective iron ions fluorescent probe based on the benz(c)acridine-1,2,3-triazole derivatives was produced by multi-step reactions. 1-(7-Benz[c]acridinyl)-4-(4-methylphenyl)-1,2,3-triazole(4 a), C_(26)H_(18)N_(4), was structurally determined by single-crystal X-ray diffraction. It crystallizes in the trigonal system, space group R-3 with a = 36.230(10), b = 36.230(10), c = 7.993(3)Å, β = 90°, V = 9086(6)Å^(3), Z = 18, D_(c)= 1.271 g/cm^(3), F(000) = 3636, μ = 0.602 mm^(-1), the final R = 0.0865 and wR = 0.1619 for 3951 observed reflections(I > 2σ(I)). X-ray analysis indicated that all four rings of benz(c)acridine are in the same plane, and the 1,2,3-triazole ring and the corresponding linked benzene(C(1)–C(6)–C(7)–C(8)–C(9)–N(1)) are approximately perpendicular with a dihedral angle of 106.5°. The crystal packing of the compound was stabilized by two weak interactions between C(11)–H(10)…N(4) and C(18)–H(18)…N(1). In fluorescence spectra studies, compound 4 c was exhibited good selectivity and sensitivity towards iron ions in DMSO: mops buffer solution. Furthermore, 4 c was successfully used for imaging iron ions in living He La cervical cancer cells.展开更多
