Abstract
This study highlights some of the effects of UV crosslinking of DNA-CTMA on its electrical and optical characteristics. The crosslinking of DNA-CTMA occurs via the photodimerization of attached coumarin moieties under UV irradiation. An exposure time of 30 min to UV light with an output power of 166 mW/cm2 is needed to complete the crosslinking process. The UV-crosslinked films show a significant increase in the electrical resistivity (decrease in leakage current) and a markedly lower dielectric constant.
