摘要

我们报告了两种新设计的双双膦芳基二吡咯烷酮（BDP 和 NDP）染料在溶液和固态中的自组装行为，这两种染料在内酰胺位置上有两个自由 N-H。有趣的是，萘基 NDP 通过 π-π 堆叠自组装形成传统的柱状液晶（LC）组装体，而较小的苯基 BDP 则通过氢键相互作用形成染料平行于柱状轴的非常规柱状 LC 相。这项研究揭示了在染料材料中调节氢键的新设计原理，有望应用于光电领域。

Influence of hydrogen bonds and π–π stacking on the self-assembly of aryldipyrrolidones†

We report on the self-assembly behaviour in solution and in the solid-state of two newly designed bisdendronized aryldipyrrolidone (BDP and NDP) dyes with two free N–H groups at the lactam positions. Interestingly, while the naphthalene-based NDP self-assembles via π–π-stacking to form conventional columnar liquid-crystalline (LC) assemblies, the smaller benzene-based BDP forms unconventional columnar LC phases with the dyes parallel to the columnar axis, via hydrogen-bonding interactions. This work presents new design principles to modulate hydrogen bonding in dye materials with potential application in optoelectronics.
