Tetracene octaesters, which were prepared by twofold [2+2+2] cocyclization, were isolated as red, orange, and orange-yellow solids for the methyl, ethyl, and propyl ester derivatives, respectively. X-Ray crystallographic analysis reveals that the difference in solid-state color arises owing to differences in molecular packing.
通过两次[2+2+2]共环化制备的并四苯八酯,分离出红色、橙色和橙黄色固体,分别为甲酯、乙酯和丙酯衍生物。 X 射线晶体学分析表明,固态颜色的差异是由于分子堆积的差异而产生的。
