摘　　要：向4-(4-二甲基氨基苯乙烯基)甲基吡啶对甲苯磺酸盐(DAST)甲醇溶液中加入对甲苯磺酸(PTSA),从中生长出DAST晶体。测试了纯生长溶液和加入PTSA后溶液的亚稳区,发现PTSA能够明显增加DAST生长溶液的亚稳区的宽度。通过粉末XRD和FTIR分别测试了PTSA掺杂和未掺杂溶液中生长的DAST晶体的晶体结构和官能团,测试结果表明PTSA并不会改变其晶体结构。溶液的稳定性有助于生长出大尺寸DAST晶体。4-N,N-dimethylamino-4 ＇-N ＇-methyl stilbazolium tosylate（ DAST） crystals were grown from methanol solutions added with toluene-sulfonic acid（ PTSA）. The metastable zone widths（ MZW） of DAST solutions with and without PTSA were measured. It was found that PTSA could enhance the MZW significantly. The crystal structure and functional groups of the grown DAST were investigated by powder XRD and Fourier transform infrared（ FTIR）,respectively. The results indicated that PTSA did not change the crystal structure. The stability of solution with PTSA was helpful to the growth of large size DAST crystal.
