A series of V-type chromophores with electron-rich heterocyclevinylene bridges have been synthesized via Wittig-Horner-Emmons and Vilsmeier reactions. All the target chromophores showed strong one-photon and two-photon excited emission, and their electron properties could be tuned by using different heterocycles such as furan, thiophene and pyrrole moieties in I-III. The maximum two-photon absorption (TPA) cross sections occurred at 760 nm and were measured to be in the range of 400-800 GM.
