The molecular and crystal structure of perfluoro-9,10-diphenylanthracene and its perfluorinated dihydro derivatives (9,10-diphenyl-1,4-dihydroanthracene, 9,10-diphenyl-2,9-dihydroanthracene, and cis,trans- 9,10-diphenyl-9,10-dihydroanthracenes) is determined by single crystal X-ray diffraction. 9,10-Diphenyl- 2,9-dihydroanthracene is analyzed in cocrystal with 9,10-diphenyl-1,4-dihydroanthracene (2:1)
全氟-9,10-二苯基蒽及其全氟二氢衍生物(9,10-二苯基-1,4-二氢蒽、9,10-二苯基-2,9-二氢蒽和顺,反-9, 10-二苯基-9,10-二氢蒽)通过单晶X射线衍射测定。在与 9,10-二苯基-1,4-二氢蒽 (2:1) 的共晶中分析 9,10-二苯基-2,9-二氢蒽。结果表明,在所研究的化合物中,苯环平面与蒽核的夹角接近90°。根据 DFT/B3LYP/6-31G(d) 计算,9,10-二苯基-1,4-二氢蒽在所研究的二氢蒽中热力学最稳定。所研究化合物的晶体中存在 C–F…π 相互作用,而没有 π 堆积相互作用。
