Source of material
4-Morpholinonaphthalen-2-ol (2.4 mmol), 1-(3-bromo-4-morpholinophenyl)-1-phenylprop-2-yn-1-ol (1.2 mmol), toluene (50 mL) and p-toluenesulfonic acid (0.24 mmol) respectively were added to a 100 mL single-mouth flask. The resultant reaction mixture was stirred at 80 °C, and TLC was used to monitor the progress of the reaction. After the reaction was completed, toluene was removed under reduced pressure. A saturated sodium carbonate solution (100 mL) was added, and the mixture was extracted with ethyl acetate (50 mL × 3). The organic phases were combined, dried over anhydrous MgSO4, and concentrated under reduced pressure. Purification of the residue furnished the title compound.
Experimental details
Hydrogen atoms were positioned geometrically.
Discussion
Photochromism is referred to as a reversible photoiso-merization process induced at least in one direction by an electromagnetic radiation between two isomers having different absorption spectra such as biindenylidenedione compounds, quaterthiophene compound, benzofuran compound [5], [6], [7], [8]. In 1992, the family of biradical compounds was first explored by Toda and Tanaka [9]. During the past years, various types of organic photochromic compounds have aroused lots of interests because of their potential applications as photoswitchable molecular devices, optical memory storage media, as well as multi-color display [10], [11], [12], [13], [14], [15], [16], [17]. For practical applications, some groups try to modulate the photochromic properties of diarylethenes, which has recently been reported. Huang’s groups gated the spectral properties of dithienylethene by means of Lewis acid-base interaction [18], [19].
In this work, we report on the synthesis of the title compound in high yield, which is a key method for the synthesis of photochromic compounds. There is one crystallographically independent molecule in the asymmetric unit, in which all bond lengths are in normal ranges. In the title crystal structure including a pyran ring, several important bond lengths are as follows: O2—C7 = 1.459 Å, C7—C14 = 1.521 Å, C14—C8 = 1.304 Å, C8—C3 = 1.471 Å, C3—C4 = 1.380 Å, C4—O2 = 1.357 Å.
