Solvatochromic shift
WebAug 8, 2024 · Abstract. Ester carbonyl stretch in a widely used organic semiconducting material, [6,6]-phenyl-C 61-butyric acid methyl ester (PCBM), has been utilized as a vibrational probe of molecular morphology in emerging electronic materials due to the sensitivity of its vibrational frequency to the local environment.Vibrational solvatochromic … WebNov 9, 2024 · Solvatochromic dyes have been used for years to gather information about chemical and biological systems [1,2,3,4,5,6,7,8] because the intramolecular charge transfer in this class of molecules shifts accompanying medium polarity changes.Depending on the direction of this shift, three types of solvatochromic behavior have been recognized in the …
