中文摘要：
合成了一种棒形的化合物4,4＇-二（α-腈基-4-苯丙氧基苯乙烯）联苯（Ben-DCSB）,利用核磁共振（NMR）、质谱（EI-MS）、傅里叶变换红外光谱（FT-IR）和元素分析等对其进行了结构表征.对Ben-DCSB重结晶粉末进行研磨后,其发光颜色从蓝绿色变成黄绿色,荧光量子效率（ΦF）从初始的52.7%变为38.7%,表明该化合物具有力致变色性质.扫描电子显微镜（SEM）、X-射线衍射（XRD）和荧光寿命等测试结果显示,这种现象是由于在外界环境刺激下改变了Ben-DCSB在聚集态下的分子堆积结构所造成的.研磨后的样品暴露在溶剂蒸气（乙醇、二氯甲烷、四氢呋喃或丙酮）或100℃温度下放置2 min又能转换回初始状态的蓝绿色荧光,表明化合物研磨后的样品具有气致和热致变色性能,且展现出可逆变色性能.对该化合物进行多次＂力-溶剂蒸气刺激＂和＂力-热刺激＂循环实验,结果显示其具有很好的荧光可逆转换性能.热分析结果显示化合物Ben-DCSB在194℃和212℃间存在向列相（纹影织构）的液晶态;其热分解温度为362℃,表明该化合物具有较好的热稳定性.
