There are mainly three kinds of substituent electronic effects derived from aromatic rings: ground-state, radical-state, and excited-state effect. However, excited-state substituent constants of ortho-substituents have not been reported up to now. In this paper, a method for extracting the excited-state substituent constant σCCoex of ortho-substituents was provided. Forty-nine 2,4′-disubstituted stilbenes were synthesized, and the UV absorption spectra of the synthesized stilbenes were determined The σCCoex values of ortho-substituents involving MeO, Me, F, Cl, Br, CF3, and CN were quantified by curve fitting method based on the measured UV absorption spectra. The rationality of the σCCoexvalues were further exptl. confirmed by measuring the UV absorption spectra of other 10 samples of synthesized 2,3′-disubstituted stilbenes and by applying these σCCoexvalues in regression anal. of the UV absorption spectra for a complicated data set of 284 organic compounds
