Overview

Structural analysis reveals self-assembled pentagonal liquid crystalline honeycombs in carbosilane bolapolyphiles, highlighting molecular design strategies for complex tessellations.

Key Points

  • To design and evaluate p-terphenyl-based bolapolyphiles bearing bulky carbosilane-based lateral groups that self-assemble into rare periodic pentagonal liquid crystalline honeycombs.
  • Synthesized p-terphenyl-based bolapolyphiles functionalized with terminal glycerol units and bulky carbosilane side-groups.
  • Systematically varied the lateral substituents using two or three cycloalkyl or branched alkyl chains at silicon branching points to evaluate phase behavior.
  • Bolapolyphiles with two cycloalkyl or branched alkyl chains spontaneously formed type-2 pentagonal liquid crystalline honeycombs with p2gg plane group symmetry over broad temperature and volume ranges.
  • Increasing the substitution to three alkyl branches restricted the pentagonal honeycomb phase stability by predominantly favoring crystalline phases.
