NMR. With suitable substituents, as in Phthal8, Phthal12, and Phthal16, these disks self-organize into a thermotropic, columnar, discotic phase. The disubstituted phthalhydrazide unit thus represents a general motif for the recognition-induced generation of supramolecular, discotic liquid crystals by self-assembly.
6,7-双(烷氧基)-2,3-二氢酞嗪-1,4-二酮在溶液中自组装成内酰胺-内酰胺三聚体圆盘,如 SEC 和 NMR 所示。使用合适的取代基,如 Phthal8、Phthal12 和 Phthal16,这些圆盘自组织成热致、柱状、盘状相。因此,二取代的邻苯二甲酰肼单元代表了通过自组装识别诱导产生超分子盘状液晶的通用基序。
