Intramolecular charge transfer effect
WebApr 14, 2024 · Enhanced intramolecular charge transfer (ICT) with increasing the polarity of the solvents in addition to the intramolecular and intermolecular H-bonding causes the progressively red shift of the fluorescence emission band from 480 nm (in hexane) to 520 nm (in methanol) (Fig. 2) [11, 30,31,32,33,34]. WebThe energy levels of the dye are indicated by horizontal lines, vertical purple arrows illustrate the transition of BADAN molecules from the ground to an excited state, blue and green arrows illustrate the radiative transitions of BADAN from PICT (planar intramolecular charge transfer state) and TICT (twisted intramolecular charge transfer state) to the …
