6,8-Di-tert-butyl-3-(2,4-dimethyl-quinolin-7-yl)-3,4-dihydro-2H-benzo[e] [1,3]oxazine:Synthesis, Crystal Structure and Luminescent Properties
摘要:
6,8-Di-tert-butyl-3-(2,4-dimethyl-quinolin-7-yl)-3,4-dihydro-2H-benzo[e] [1,3]oxa-zine (1) was obtained by one-pot reaction starting from 2,4-di-tert-butylphenol, 7-amino-2,4-dimethyl-quinoline and paraformaldehyde. The compound was structurally characterized by NMR, IR and single-crystal X-ray diffraction along with the elemental analysis. Compound 1 crystallizes as solvate with chloroform. The solvate 1·CHCl3 (C28H35Cl3N2O, Mr=521.93) belongs to the triclinic system, space group P1 with a=10.852(2), b=11.352(2), c=13.050(3) Å, α=101.95(3), β=92.94(3), γ=114.64(3)o, V=1412.4(5) Å3, Z=2, Dc=1.227 g/cm3, F(000)=552, μ=0.347 mm-1, R=0.0959 and wR=0.2725 (I>2σ(I)). The chloroform molecule displays a rotational disorder as one chloro atom can be located at two different positions. The packing of 1·CHCl3 was further stabilized by intramolecular C-H…O interactions, intermolecular C-H…N interactions, C-H…π interactions, and π…π interactions. The luminescent properties of compound 1 in both methylene chloride solution and the solid state were studied.
