dc.description.abstract | Photophysical and TPA properties of series of push-pull aryl(bi)thiophene chromophores bearing electron-donating (D) and electron-withdrawing (A) end-groups of increasing strength are presented. All compounds show an intense Intramolecular Charge Transfer (ICT) absorption band in the visible region. Increasing the D and/or A strength as well as the length of the conjugated path induces a bathochromic and hyperchromic of the absorption band as reported for analogous push-pull polyenes. Yet, in contrast with corresponding push-pull polyenes, a significant increase in fluorescence is observed. In particular, chromophores built from a phenyl-bithienyl conjugated path and bearing strong D and A end-groups were found to combine very large one and two-photon brightness as well as strong emission in the red/NIR region. These molecules hold promises as biphotonic fluorescent probes for bioimaging. | por |
