摘要:
A novel calix[4]arene chromophore 1 was synthesized by introduction of two D-pi-A units (4-nitrophenyl)azophenyloxy groups) on the lower rim of calix[4]arene. The measurement results of hyper-Rayleigh scattering (HRS) and UV-vis spectra show that the static first molecular hyperpolarizability of the chromophore 1 is more than two times that of the corresponding mono-D-pi-A unit reference compound 4-(4-nitrophenylazo)phenol 2, without causing red-shift of absorption band.
