“…We suppressed undesired cross reactions through the noncovalent interactions of an anionic micelle with the charges of the reactants, intermediates, and products: the cationic light-harvesting complex remains affixed to the micelle surface, which blocks the access of the negatively charged sacrificial donor, aryl radical anion and hydrated electron, but allows the pyrene ground-state almost unhindered entry into the Stern layer despite a carboxylate substituent by virtue of its large dipole moment. …”

“…The decreasing polarity of the cybotactic region of pyrene with increase in the chain length “n” indicates an increased extent of packing of cationic head groups in the Stern layer. DF(–) ion seems to play a vital role in the formation of the resulting aggregates, as probed by small angle neutron scattering and transmission electron microscopy. …”

“…Results have revealed complex formation, unfolding, and a static quenching mechanism in the interaction of gemini surfactants with α-CHT. The Stern–Volmer constant (K(SV)), quenching constant (k(q)), the number of binding sites (n), and binding constant (K(b)) were interrogated by utilizing the fluorescence quenching method, UV–vis, synchronous, 3-D, and resonance Rayleigh scattering fluorescence studies. …”

“…The UV-vis and steady-state fluorescence parameters indicated a ground-state association between HSA and 4-TPyP and the absence of any dynamic fluorescence quenching was confirmed by the same average fluorescence lifetime for HSA without (4.76 ± 0.11 ns) and with 4-TPyP (4.79 ± 0.14 ns). Therefore, the Stern–Volmer quenching (K(SV)) constant reflects the binding affinity, indicating a moderate interaction (10(4) M(−1)) being spontaneous (ΔG°= -25.0 kJ/mol at 296 K), enthalpically (ΔH° = -9.31 ± 1.34 kJ/mol), and entropically (ΔS° = 52.9 ± 4.4 J/molK) driven. …”
