چکیده انگلیسی
Single crystals of 3-methyl-4-methoxy-4â²-nitrostilben (MMONS) of large size (40Ã32Ã32 mm3) and excellent quality were grown by the low-temperature solution growth method using methyl ethyl ketone as a solvent. Supersaturation was established by lowering the temperature at a rate of 0.07 °C/day at the initial stage and 0.3 °C/day at the final stage. MMONS crystals showed unidirectional growth along the polar axis, which can be explained by the molecular recognition concept. The overall morphology is represented by a truncated octahedron covered with {1 1 1}, {2 1 1¯}, {1 2 0}, {1 0 0} and (0 0 1) faces. Crystal perfection was characterized by using white beam synchrotron X-ray topography, which shows perfection of high degree.
