Abstract

A series of dipolar-type terphenyl derivatives 13 featuring an electron donor (p-NMe2C6H4 group) and acceptor (p-NO2C6H4 group) unit was synthesized and their photophysical properties were investigated. By using aromatic heterocycles (thiophene, furan, pyrrole) as the π-linkers between the donor and acceptor units, significant effects on the bathochromic shift and enhancement of the two-photon absorption wavelength and the two-photon absorption cross-sections were observed, respectively.
