## Abstract ^13^C NMR spectra of 39 thiophene and furan chalcone analogues in CDCl~3~ solutions are reported. The effect of substituents on the ^13^C chemical shifts in the phenyl and in the 5βmembered rings is discussed. ^13^C NMR shifts are correlated with Hammett parameters and with experimental
Static quenching (T=77K) of luminescence of naphthalene derivatives via CT complexes in solid state with tetracyanoethylene has been studied. The linear correlation between the logarithm of K quenching constant and 1 Q CT frequency in electronic absorption spectra of CT complexes has been observed.
