Achiral stilbene polycatenars forming smectic, columnar or cubic phase depending on the terminal chains length, were studied. The cubic Im3m phase exhibited optical activity originating in twisted face-to-face molecular aggregates. The optical activity of the phase is preserved upon sample crystallization, providing evidence of a transfer of chirality on a molecular level.
研究了根据末端链长度形成近晶相、柱状相或立方相的非手性二苯乙烯多链节化合物。立方Im3m相表现出源于扭曲面对面分子聚集体的光学活性。该相的光学活性在样品结晶后得以保留，这为分子水平上手性转移提供了证据。
