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.Fundação para a Ciência e a Tecnologia (FCT)Royal Society of ChemistryUniversidade do MinhoGenin, EmileHugues, VincentClermont, GuillaumeHerbivo, CyrilComel, AlainCastro, M.
