The title compound 2,5-bis(morpholino)-3,4-bis(p-chlorophenyl) thiophene 2 was obtained by the reaction of -thio-p-chlorobenzoyl thioformmorpholine 1 with trimethyl phosphite in refluxing xylene. The crystal is of triclinic, space group P?with unit cell constants: a = 6.0740(1), b = 10.3250(1), c = 19.779(2) , ?= 76.740(1), = 87.110(1), = 74.920(1), C24H24Cl2N2O2S, Mr = 475.41, Z = 2, V = 1165.7(3) ?, Dc = 1.354 g/cm3, (MoK) = 0.71073, = 0.392 mm-1, F(000) = 496, the final R = 0.0324 and wR = 0.0819 for 3102 observed reflections (I > 2(I)). X-ray analysis reveals that the two morpholinyl groups are located at the -position of thiophene, and the two p-chlorophenyl groups at the -position. Therefore, the title compound is a new symmetric thiophene derivative. 展开更多

The crystal structure of the title compound 1-(4-fluorophenyl) -2-hexylthio-benzo [4,5]furo[3,2-d]-1,2,4-triazolo[1,5-a]pyrimidin-5(1H) -one(C23H21FN4O2S,Mr = 436.5) has been prepared and determined by single-crystal X-ray diffraction. The crystal is of monoclinic,space group P21/n with a = 13.9854(3) ,b = 17.2678(4) ,c = 18.1828(5)A,β = 99.364(2) °,V = 4332.58(18) A^3,Z = 4,Dc = 1.338,F(000) =1824,μ = 0.185 mm^-1,MoKa radiation(λ = 0.71073) ,R = 0.0538 and wR = 0.1162 for 4728 observed reflections with I 〉 2σ(I) . X-ray diffraction analysis reveals the fused rings of benzo[4,5]furo[3,2-d]-1,2,4-triazolo[1,5-a] pyrimidin-5(1H) -one system are nearly coplanar. The crystal packing is mainly stabilized by weak intermolecular C-H···O hydrogen bond and π-π interactions. 展开更多

Geometry optimization and subsequent harmonic vibration calculations of prior synthesized (E)-3-(4-fluorophenyl)-N-[4-(phenyl-amino) quinazoline-7-yl] acrylamide were carried out by DFT/B3LYP method with both 6-31G and 6-311G basis sets.The Infrared (IR) spectrum of the title compound was recorded in the field of 400-4000 cm 1 and then assigned.The correlation analyses between the scaled theoretical vibration frequencies and the experimental ones indicate that there exist good linearity relationships since the correlation coefficients R 2 are larger than 0.999.The intramolecular interactions existed in the title molecule were confirmed by the Atoms in molecules (AIM) method,and their influences on the absorption frequency were also investigated. 展开更多

The chiral molecule (+)-N-[(3S)-3-(4-fluorophenyl)heptanoyl]bornane-10,2-sultam (C23H32FNO3S, Mr = 421.56), a fluorine-containing derivative of camphorsultam, was conveniently obtained and crystallized in the orthorhombic space group P212121 with a = 7.9044(11), b = 11.6680(16), c = 24.899(3) , V = 2296.4(5) 3, Z = 4, Dc = 1.219 Mg/m3, λ = 0.71073 , μ(MoKα) = 0.172 mm-1 and F(000) = 904. X-ray diffraction analysis reveals that the six-membered ring of sultam shows a boat conformation (Fig. 1). The planes constructed by ((C6), (C7), (C8), (C9)) and ((C4), (C5), (C6), (C9)) form a dihedral angle of 70.3(3)°. The plane of (C1)-(C2)-(C3) forms dihedral angles to the aforementioned planes of 85.9(4) and 89.5(4)°, respectively. The molecules are linked via C-H···O/F interactions. 展开更多

By converting incident light into electric power,self-powered electrochromic window(SP-ECW)can achieve color change in electrochromic layer with no need for external voltage.In this work,a newly-de signed SP-ECW is proposed for altering its color between deep blue and colorless state according to on/off state of incident light.The device consists of a working electrode with planar integration of photovoltaic(PV)and electrochromic(EC)elements on one electrode,a platinum counter electrode and a redox electrolyte comprising Br^-/Br_3^-couple.A high transmittance modulation of 41%at 582 nm is obtained.Electrical energy converted from light is not only sufficient to drive the device,but also can be outputted to the external circuit. 展开更多
