Abstract
Abstract In this contribution, we have presented the dynamics of molecular rotor dye thioflavin T (ThT) in Stern layer of sodium dodecyl sulfate (SDS) micelle using femtosecond fluorescence up-conversion and broadband transient absorption spectroscopy. ThT being a positively charged molecule is expected to remain in the Stern layer of micelle due to columbic attraction with the negatively charged surfactant head groups. The restriction imposed by the environment slows down the rotation of molecular fragments, which increases its quantum yield ∼8 times compared to pure water. We have confirmed the dual relaxation channel of ThT (LE → TICT1 and LE → TICT2) and found that the lifetime of the three states namely LE, TICT1 and TICT2 are 0.5, 3.1 and 15.7 ps respectively in 40 mM SDS.
