Application

Intermolecular charge-transfer states at the interface between electron donating (D) and accepting (A) materials are crucial for the operation of organic electronics, such as solar cells, transistors and organic light-emitting diodes (OLEDs). The 4,7-Diphenyl-1,10-phenanthroline, also known as Bathophenanthroline (Bphen) enables use as Electron Transport / Hole Blocking Layer (ETL / HBL) in your organic electronic devices. It has a μe of about 3.0 x 10-4 cm2 V−1 s−1 and is solution-processable.
