aggregation-induced enhanced emission (AIEE) properties. Notably, DSA, 4-BFSA, 3-BFSA and BDFSA display solvatochromic properties. The relationship between their structures and photophysical properties was further discussed. This work has demonstrated that depending on the amount and position, fluorine substitution can tune the structures and photophysical properties of DSA effectively.
由于氟取代的位置和程度的不同,四种氟化的DSA(9,10-二苯乙烯基蒽)衍生物,即9,10-双(4-氟苯乙烯基)蒽(4-BFSA),9,10-双(3) -氟苯乙烯基(3-BFSA),9,10-双(3,5-二氟苯乙烯基)蒽(BDFSA)和9,10-双(3,4,5-三氟苯乙烯基)蒽(BTFSA),显示出不同的晶体堆积和固态的光物理性质 此外,已经研究了溶液中的光物理性质。结果表明,所有四种化合物均表现出可调节的聚集诱导增强发射(AIEE)特性。值得注意的是,DSA,4-BFSA,3-BFSA和BDFSA显示溶剂变色性质。进一步讨论了它们的结构与光物理性质之间的关系。这项工作表明,根据取代的量和位置,氟取代可以有效地调节DSA的结构和光物理性质。
