Abstract

The photophysical and nonlinear properties of some push-pull fluorinated 4-(dicyanomethylene)- pyranes using the steady- sate and time-resolved picosecond spectroscopies with an electric-field-induced second-harmonic-generation technique have been investigated. Strong fluorescence quenching and large shifts of time-resolved transient picosecond spectra on going form nonpolar to polar solvents are connected with effective charge transfer interactions of polar singlet excited molecules with a polar environment. The high second- order polarizabilty (beta) equals 260 X 10^-30 esu for one of the investigated push-pull pyranes allows to propose using such kind of molecules in the development of second- harmonic-generation elements.
