摘要: Abstract Cyclame and hexacyclene derivatives, bearing four six long-chain substituents respectively, were synthesized. They are discussed as monolayer-forming amphiphiles well liquid-crystalline-phase-forming thermotropic mesogens. The compounds investigated form ordered monolayers at the gas/water interface. In monolayer hydrophilic cyclic head group lies flat on water surface, whereas hydrophobic oriented perpendicularly with respect to Most derivatives fitted aromatic exhibit a solid condensed state exclusively. contrast this, expanded phases can be found when spreading aliphatic-substituted compounds. latter case, onset of phase transition takes bump-like shape, owing kinetic reasons. A liquid-crystalline columnar order is only achieved hexacyclenes substituents, etherified one alkyl chain. Besides remaining melt from th...
