B2PymPm


Product Code M2173A1
Price £266.00

B2PymPm, 4,6-Bis(3,5-di(pyridin-2-yl)phenyl)-2-methylpyrimidine, has a 2-methylpyrimidine core with four pyridine pendants. It is used as an electron-transport layer or hole-blocking layer material for OLED or photovoltaic devices.

Pyridine rings enable intramolecular and intermolecular hydrogen bondings in and between the molecules. This can cause the molecules to become planar and enhance the horizontal molecular orientation, thus leading to high charge mobility.
