Polar order by rational design: crystal engineering with parallel beloamphiphile monolayers

Area of Science:

• Materials Science
• Chemistry
• Physics

Background:

• Large-scale polar order is difficult to achieve in biological systems, often limited to nanoscale domains or cancelled out.
• The dipole alignment problem questions the possibility of macroscopic polar order.

Purpose of the Study:

• To investigate the feasibility of achieving large-scale polar order in molecular crystals.
• To design and synthesize novel materials exhibiting perfect polar order.

Main Methods:

• Interdisciplinary approach combining mathematics, computational chemistry, and synthetic chemistry.
• Crystallization and crystallographic analysis.
• Investigation of intermolecular bonding in molecular crystals.

Main Results:

• Successfully designed and synthesized azine- and biphenyl-based beloamphiphiles.
• These novel compounds exhibit perfect polar order.
• Demonstrated a new generation of highly anisotropic functional materials.

Conclusions:

• Achieving large-scale polar order in molecular crystals is possible.
• The developed beloamphiphiles represent a significant advancement in functional materials.
• This work addresses the long-standing dipole alignment problem.
