E,E-1,4-Bis(2,4-ditrifluoromethylstyryl)benzene (d24CF3) and E,E-1,4-bis(3,5-ditrifluoromethylstyryl)benzene (d35CF3) were synthesized. The d35CF3 crystals grown from solution displayed a unique fibrous form and emitted propagated fluorescence, and a d35CF3 film demonstrated a very low ionization potential of −6.7 eV. Meanwhile, d24CF3 crystals exhibited aggregation-induced emission.
合成了 E,E-1,4-双(2,4-二三
氟甲基苯乙烯基)苯(d24CF3)和 E,E-1,4-双(3,5-二三
氟甲基苯乙烯基)苯(d35CF3)。从溶液中生长出来的 d35CF3 晶体呈现出独特的纤维状,并发出传播荧光,d35CF3 薄膜的电离电位非常低,仅为 -6.7 eV。同时,d24CF3 晶体显示出聚集诱导发射。
