Precipitates or xerogels of 1,3-bis[(3,4-dioctyloxy phenyl) hydrazide] phenylene (BP8-C) from ethanol or toluene were demonstrated to show three different aggregate structures depending on different cooling procedure, i.e. cubic phase and two kinds of hexagonal columnar phase (denoted as Col_h1 and Col_h2). DSC measurement indicated that cubic-Col_h1 and Col_h1-Col_h2 transition showed endothermic behavior while Col_h2-Col_h1 transition showed exothermic, indicating cubic structure was the most stable. Annealing of the BP8-C/ethanol suspension or the BP8-C/toluene gel caused the gradual structural transitions from either Col_h1 to cubic or Col_h2 to cubic phase. Higher incubation temperature, longer annealing time, or polar solvent could accelerate the transitions from instability structure to stability ones in the gels.

来自乙醇或甲苯的1,3-双[（3,4-二辛氧基苯基）酰肼]亚苯基（BP8-C）的沉淀或干凝胶被证明显示出三种不同的聚集体结构，这取决于不同的冷却程序，即立方相和两种六方柱状相（分别表示为Col _h1和Col _h2）。DSC测量表明，立方-Col _h1和Col _h1 -Col _h2转变显示出吸热行为，而Col _h2 - Col _h1转变显示出放热行为，表明立方结构最稳定。BP8-C /乙醇悬浮液或BP8-C /甲苯凝胶的退火引起从Col _h1的逐渐结构转变到立方或Col _h2到立方相。较高的温育温度，较长的退火时间或极性溶剂可加速凝胶中从不稳定结构到稳定结构的转变。
