The electric dipole moments of some substituted stilbenes in the ground (μg) and the first excited singlet state (μe) have been determined and discussed in regard of the donor-acceptor- interactions. A linear correlation between the Hammett σp-constants and the values of μg, μe and Δμ = μe - μg for different substituted stilbenes was found.

AbstractThe effect of substituents on the fluorescence quantum yield φf of trans-stilbenes (1) in dimethylformamide, acetonitrile, and n-propanol, as well as in n-heptane, is mainly due to radiationless deactivation. Contrary to n-heptane, the rate kd of radiationless deactivation in the above mentioned polar solvents for compounds 1 of similar structure is not a monotoneous function of the polarity of the first excited singlet state. The maximum of kd corresponds to compounds with medium polarity (1h, 1i). The effect of substituents on the fluorescence rate kfn in polar and nonpolar solvents is small compared to that on kd. In all solvents kfn drops with increasing polarity of the first excited singlet state.

Abstract The effect of substituents R (R=N(CH3)2, OCH3, CH3, H, Cl, Br, CN) on the polarity of trans-styryl-methyl-sulfones in the first excited singlet state is investigated. Linear relations are found between the dipole moment in the excited state, μe, and the Hammett constant, σp+ , and also between μe and the dipole moment in the ground state, μg. On increasing the electron-donor power of R, μe grows faster than μg.
