ABSTRACT

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.
