Two is better than one: a luminogen comprised of two units of tetraphenylethene (BTPE) emits more efficiently than that with one tetraphenylethene unit in the solid state; self-assembly of the BTPE molecules affords crystalline microfibers that fluoresce in 100% efficiency, giving the largest effect of aggregation-induced emission (alpha(AIE)-->infinity); BTPE-based electroluminescence devices emit in current efficiency up to approximately 7.3 cd/A.
两个总比一个好
一个由两个四苯乙烯（BTPE）单元组成的发 光体在固态下比一个四苯乙烯单元的发光体效率更高；BTPE 分子的自组装提供了结晶微纤维，在 100%效率下发出荧光，产生最大的聚集诱导发光效应（α（AIE）-无穷大）；基于 BTPE 的电致发光器件的电流效率高达约 7.3 cd/A。
