Dye aggregation and influence of pre-micelles on heterogeneous catalysis: A photophysical approach

Steady state and time-resolved fluorescence spectroscopy of quinine sulfate dication in ionic and neutral micelles: Effect of micellar charge on photophysics

“…The fluorescence lifetime of a fluorophore in micellar solutions is very sensitive to the local environment around the probe and helps to understand the different interactions between the probe molecule and the micelle, the location of the probe in micelles and the local viscosity and polarity of the microenvironment [32][33][34][35][36][37][38][39][40][41]. Differential degrees of solvent motion around the fluorophore or partitioning of the fluorophore in distinct regions of a confined environment of micelles gives rise to different fluorescence lifetime components.…”

“…The fluorescence anisotropy measurement of a probe molecule has been established to be a most powerful and sensitive technique to elucidate information about the complex micro heterogeneous environment [37][38][39][40][41]. In order to obtain the location and mobility of QSD molecule in micellar systems, time resolved anisotropy measurements were performed.…”

Effect of nanosize micelles of ionic and neutral surfactants on the photophysics of protonated 6-methoxyquinoline: Time-resolved fluorescence study

“…The fluorescence anisotropy measurement of a probe molecule has been established to be a most powerful and sensitive technique to know information about the complex micro heterogeneous environment [48][49][50]47,54]. Rotational relaxation and dynamics of a probe molecule in micellar assembly is determined using time resolved anisotropy measurements.…”

“…The lifetime determines the time available for the fluorophore to interact with or diffuse in its environment. Lifetime measurements can yield information about the molecular microenvironment around the fluorescent molecule and help us to understand the interaction between the probe molecule and micelles, the location of the probe in micelles and local viscosity and the polarity of the microenvironment [41][42][43][44][45][46][47][48][49][50]. Factors such as ionic strength, hydrophobicity, oxygen concentration, binding to macromolecules, and the proximity of molecules that can deplete the excited state by resonance energy transfer can all modify the lifetime of a fluorophore.…”

Photophysical Investigation of 8-amino 2-Naphthol in Different Micellar Environment

“…The fluorescence lifetime of a fluorophore in micellar solutions is very sensitive to the local environment around the probe and helps to understand different interactions between the probe molecule and the micelle, the location of the probe in micelles and the local viscosity and polarity of the microenvironment [41][42][43][44][45][46][47][48][49][50]. Differential degrees of solvent motion around the fluorophore or partitioning of the fluorophore in distinct regions of a confined environment of micelles gives rise to various fluorescence life time components.…”
