Nucleobases for optoelectronics

This paper will review the use of nucleobases for optoelectronic applications. Nucleobases possess unique electromagnetic, optical, mechanical and thermal properties, including low optical loss and simultaneous low electrical resistivity, high temperature stability and a strong resistance to organic solvents. They are also hydrophobic, providing excellent hermetic sealing. They can be vapor deposited for a number of applications. Nucleobases have highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) levels suitable for charge blocking layers in organic light emitting diodes (OLEDs) and nonlinear polymer electro-optic modulators. With their low optical loss, they may prove suitable for optical waveguiding applications.
