Single-site group 4 metallocene catalytic systems have enabled us to produce polyolefins with the tailored polymer architecture in terms of molecular weight, functionalities, and degree of functionalization, which in turn may lead to intriguing properties. Particularly, polyolefins bearing triarylamine (TAA) functionality could be of great interest in display applications like OLEDs since they can possess hole-transporting properties. In this regard, we recently reported that polyethylene bearing triphenylamine group can act as hole-transporting layer materials in OLEDs. As part of our continuous contributions to this area, we have investigated the effects of catalyst structure and triarylamine functionality on the ethylene/-olefin copolymerization. The details of synthesis, characterization and photophysical properties of polymers will be presented. |
