The achiral liquid crystalline materials showing two B4 (HN) phases have been found to exhibit strong gelation ability for various organic solvents with reversible sol–gel phase transition. The gel is formed by helical tubules, which build entangled 3D network, encapsulating the solvent. The equilibrium of left- and right-handed tubules is preserved in the gel, even if the chiral solvent is used.
研究发现,呈现两种 B4(HN)相的非手性液晶材料对各种有机溶剂具有很强的凝胶化能力,并具有可逆的溶胶-凝胶相变。凝胶由螺旋管形成,螺旋管构建了缠结的三维网络,将溶剂包裹起来。即使使用手性溶剂,凝胶中也能保持左旋和右旋小管的平衡。
