Solution Growth And Characterization Of High-Quality Organic 4-N,N '-Dimethylamino-N-Methyl-4-Stilbazolium Tosylate Crystals

High-quality 4-N,N'-dimethylamino-N-methyl-4-stilbazolium tosylate crystals has been grown onto a seed from supersaturated methanol solution by controlled temperature lowering method. XRD studies confirm structural perfection of the grown crystals. The functional groups of DAST were identified by FTIR studies. The average values of microhardness obtained on the surface and on the cleaved facet of the grown crystals are different and amount 28.1 and 32.6 kgf/mm(2), respectively. There is established a correlation between the values of microhardness and the character of distribution of dislocations in the DAST crystals.
