General description

TFB, a hole transporting material and an electron-blocking layer, has high hole mobility, low electron affinity, and high ionic potential. Its electron blocking nature results in effective confinement of injected charge carriers in the perovskite layers.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, are prone to degradation in ambient conditions.Click here for more information.

Application

TFB can be used in the formation of multilayer quantum dot-based light-emitting diodes (LEDs). It can also be used in the fabrication of highly responsive gas sensors for breath analysis.
