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

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(C28 H35 Cl3 N2 O, Mr = 521.93) belongs to the triclinic system, space group P1 with a = 10.852(2), b = 11.352(2), c = 13.050(3), α = 101.95(3), β = 92.94(3), γ = 114.64(3)o, V = 1412.4(5)3, Z = 2, Dc = 1.227 g/cm3, F(000) = 552, μ = 0.347 mm–1, R = 0.0959 and wR = 0.2725(I > 2?(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.
