| pubmed-article:17150493 | pubmed:abstractText | 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. | lld:pubmed |
