| dc.description.alternative | Spectral properties of a newly synthesized thioflavin T (ThT) derivative, trans-2-[4-(dimethylamino)styryl]-3-ethyl-1,3-benzothiazolium perchlorate (DMASEBT) with absorption and fl uorescence spectra shifted to longer wavelengths (than ThT), were studied. Quantum-chemical calculations established that DMASEBT is planar in the ground state.The energy minimum of the excited molecule corresponded to a twisted conformation (TICT-state) with a 90° angle between the planar fragments. Charge in the molecule edistributed and a non-fl uorescing TICT-state was formed if the fragments rotated. Fluorescence occurred from the non-equilibrium excited state (LE-state). It was shown that limited torsional rotation of the molecular fragments and; therefore, a decreased probability of transitioning into the non-fl uorescing TICT-state, were responsible for the signifi cantly increased quantum yield and fl uorescence lifetime of DMASEBT upon increasing the solvent viscosity and incorporating it into amyloid fi brils. | ru |
