A novel twistacene 11,12‐dichloro‐9,14‐diphenyldibenzo [de, qr]tetracene (TPyC) has been synthesized in one pot through classical Diels‐Alder cycloaddition reaction and fully characterized. Its analogues TPyO, TPyS, TPyF and TPyB were re‐prepared through the reported methods. All of them emitted blue fluorescence in toluene solution. The self‐assembly properties based on the as‐prepared molecules were examined in detail by re‐precipitation method, suggesting that the terminal substituents, temperature and solvent could affect the aggregation morphology in large part.

取代的丙烯衍生物：合成，光学性质和自组装行为

一种新颖的twistacene 11,12-二氯9,14-diphenyldibenzo [德，  q或r ]并四苯（TPyC）已以一锅通过经典狄尔斯-阿尔德环加成反应合成了完全表征。通过报道的方法重新制备了其类似物TPyO，TPyS，TPyF和TPyB。它们都在甲苯溶液中发出蓝色荧光。通过再沉淀方法详细研究了基于所制备分子的自组装性能，这表明末端取代基，温度和溶剂可能在很大程度上影响聚集形态。
