摘要：

A new metastable liquid-crystalline phase BP S was observed in pure chiral compounds. The BP S is transformed reversibly from the supercooled BP I and is thermodynamically stable with respect to the BP I and metastable to the cholesteric phase. Rhombic single crystals of the BP S probably indicate a cubic lattice structure as in other BPs, but the lattice constant exhibits an anomalous temperature dependence.
