分子聚集极大地影响了双苯乙烯基苯衍生物的荧光量子效率、瞬态寿命和放大自发辐射（ASE）。我们比较了各种形态（溶液、薄膜、掺杂薄膜和单晶状态）的光学性质（见图），并证明了场效应晶体管中1，4-双（4-甲基苯乙烯基）苯层的双极操作导致了具有相当尖锐的发射宽度的强烈蓝色电致发光。
Molecular aggregation greatly affects the fluorescence quantum efficiency, transient lifetime, and amplified spontaneous emission (ASE) of bis-styrylbenzene derivatives. We compare the optical properties for various morphologies (solution, film, doped film, and single crystalline state) (see figure) and demonstrate that ambi-polar operation of a 1,4-bis(4-methylstyryl) benzene layer in field-effect transistors leads to intense blue electroluminescence with a rather sharp emission width.
