The nonlinear optical properties of heterocyclic compounds (1-7) were investigated. π-Centers benzo[1,2-b:4,3-b']dithiophene (1) and trithia[5]helicene (5) were studied. Compounds 2-4, 6 and 7 possess either donor-π (D-π) or donor-π-acceptor (D-π-A) structures. The optimized geometry of 7 shows a 3D helical structure. Two-photon absorption cross-sections related to the third-order nonlinear susceptibility were measured using open-aperture Z-scan techniques. Compound 7 has a two-photon absorption cross-section of 103 GM when excited at 720 nm. Important molecular structure-nonlinear optical property relationships are formulated.
