Novel tris D-π-A substituted triphenylcarbinol derivatives have been synthesized and studied for their mol. second-order nonlinear optical properties by elec. field induced second harmonic generation and hyper Rayleigh scattering (HRS). Compared to their Ph analogs with only one D-π-A system, the triphenylcarbinol derivatives I (R = NO2, R1 = H; R = CHO, R1 = Me) and II (R = CN, NO2) exhibit an increased hyperpolarizability (〈β〉HRS) without the undesired red-shift of the charge-transfer band. The dipole moments and hyperpolarizabilities depend on both the close proximity (3-4 Å) and the orientation of the three NLO-phore units. The nature of the acceptor substituent strongly influences the magnitude of the 〈β〉HRS values. I (R = NO2, R1 = H) exhibits a 〈β〉HRS value of 15 × 10-31 esu, which is almost the same as that of its reference compound, p-nitroanisole, whereas II (R = NO2) exhibits a 〈β〉HRS value of 338 × 10-30 esu, which is >3 times larger than that of its reference compound, 4-methoxy-4′-nitrostilbene.
