文摘

A series of new N-arylpyrrole-based chromophores with the donor-蟺-donor structure have been designed and synthesized via Wittig鈭扝orner鈭扙mmons olefination and Suzuki coupling reactions. The electronic and optical properties of the designed chromophores could be well tuned by modifying the conjugation bridges and changing the groups linked to the pyrrole moieties through the C鈥擭 single bond. All the chromophores exhibited two-photon absorption activity in the range of 730鈭?00 nm with a large two-photon absorption cross section (1000鈭?700 GM).
