Abstract

The preparation of organic-soluble DNA bearing carbazole side chain (Cz-DNA) was carried out and the resulting Cz-DNA shows good solubility in alcohol, which allows the fabrication of thin films for studying the photophysical properties of DNA in a solid state. We demonstrated the absorption and photoluminescence behaviors of new soluble Ir(III) complex in two polymer hosts of Cz-DNA and poly(N-vinylcarbazole) (PVK). We compared the absorption and photoluminescence (PL) spectra with the concentration of Ir(III) complex. The Ir(Cz-ppy)3 in Cz-DNA was observed to have a larger quantum yield and induce enhancement of green emission of Ir(Cz-ppy)3.
