  • Title: Synthesis and fluorescence properties of oligonucleotides containing pyrene-dimethylaniline chromophore.
    Author: Okamoto A, Nishiza K, Saito I.
    Journal: Nucleic Acids Symp Ser (Oxf); 2004; (48):91-2. PubMed ID: 17150493.
    Abstract:
    The photophysical properties of DNA oligomers containing novel uracil derivatives tethering a solvatochromic pyrene-dimethylaniline (Py-DMA) chromophore were investigated. In the steady-state fluorescence measurements of the modified DNA oligomer, dual fluorescence, originating from a locally excited (LE) and a twisted intramolecular charge transfer (TICT) state, was observed.
