Source of material
All reagents and solvents were commercially available and used as received without further purification. Azobenzene-3,3′-dicarbonylchloride (3 mmol) was added to a solution of ethanol (25 mL) and 1,2-dichloroethane (15 mL). The reaction mixture was stirred at 80 °C for 3 h, then the solution was naturally cooled to room temperature. After filtration orange flakes of the title compound were obtained with 94.6% yield. Crystals suitable for X-ray diffraction were obtained by slow evaporation of a solution including 0.05 g of the product in methanol (5 mL) and chloroform (5 mL).
Experimental details
H atoms were subsequently treated as riding atoms with distances C—H = 0.96 (CH3), 0.97 (CH2), 0.93 Å (ArH) and O—H = 0.85 Å.
Comment
In recent years, the study of liquid crystalline materials has been of interest due to their potentially wide range of applications, such as in electrical [5], optical [6], and biological medical fields [7]. In this respect, the preparation of liquid crystalline materials containing azobenzene moieties appears to be very promising, because the photoinduced trans-cis isomerization of azobenzene chromophores can give rise to photochromic and optical dichroic effects [8]. Liquid crystalline polymers containing azobenzene derivatives have been widely investigated for the photo-controlled release of drugs [9], the preparation of holographic optical memories [10], and non-linear optical materials [11]. In order to enlarge the number of azobenzene derivatives, the synthesis and crystal structure of the title compound was investigated.
The title crystal structure is centrosymmetric and contains one half of a title molecule in the asymmetric unit. Consequently the title molecule is located around an inversion center in the monoclinic space group P21/n (cf. the figure). Thus the intersection angle between two aryl rings is 0°, which is the same to that of azobenzene [12]. The crystal packing does not exhibit classical hydrogen bond interactions.
