High-purity (>99.0%) and available online for priority dispatch, Bis(2-(2-hydroxyphenyl)benzothiazolate) zinc (II), CAS No. 58280-31-2, Sublimed ≥99.0%
Zn(BTZ)2 is one of the most studied high efficient electroluminescent material. It has also been widely used as an excellent electron transporting materials in OLEDs [1].
Zn(BTZ)2 exhibits an unusual broad electroluminescent (EL) emission and for this reason, a single-emitting component for white light emitting diodes can be fabricated by using Zn(BTZ)2 as emitting layer material [2]. It has also been reported that with an insertion of rubrene layer, the purity of the white light emitting of Zn(BTZ)2 can be improved [3].
