Abstract:Substituent effects (SEs) are fundamental for predicting molecular reactivity, while polyene, polyyne and acene derivatives are precursors to compounds with diverse applications. Computations were performed for Y‐R‐X systems, where reaction sites Y = NO2 and O−, substituents X = NO2, CN, Cl, H, OH, NH2, and spacers R = polyene, polyyne (n=1‐5, 10 repeating units) and acene (up to tetracene). The cSAR (charge of the substituent active region) approach allowed to present, for the first time, quantitative relatio… Show more
