Diverse effect of PEO–PPO–PEO and PPO–PEO–PPO triblock copolymers on temperature responsive behavior of luminescent hard–soft colloids

Triblock copolymer-based luminescent organic–inorganic hybrids triggered by heating and fluoroquinolone antibiotics

“…This phenomenon can be detected by dynamic light scattering (DLS) measurements at various temperatures. The micelles appear as 10-12 nm aggregates at the temperature of micellization (CMT) [30]. The CMT point is 34°C when the concentration of L64 is 10 mM, and increases with decrease in L64 concentration [30].…”

“…The triblock copolymer L64 undergoes temperature-induced micellization in aqueous solutions [27][28][29][30]. This phenomenon can be detected by dynamic light scattering (DLS) measurements at various temperatures.…”

“…Triblock copolymers (PEO) 13 (PPO) 30 (1) was prepared in accordance with the previously reported procedure. Mo powder was pre-treated with H 2 (700˚C) to remove oxides, KI was dried in vacuum at 100˚ C for several hours prior to use, I 2 was freshly sublimed [21].…”

“…Mo 6 I 14 ] in the (PEO)13 (PPO)30 (PEO) 13 (L64)-based solutions at specific concentration conditions results in the formation of organicinorganic hybrids exhibiting peculiar colloid and luminescent properties. The temperatureinduced aggregation behavior of the L64-based organic-inorganic hybrids results in the temperature-dependent cluster-centered luminescence.…”

Passive optical mapping of structural evolution in complex fluids

“…The structural evolution of such complex uids has been intensely studied by means of SANS, 22,23 laser temperature jump, 24 ultrasonic relaxation, 25 differential scanning calorimetry (DSC), 21 Fouriertransform infrared spectroscopy (FTIR), 21 and both SLS and DLS. 21,22,25,26 The concentration and temperature regimes covered by these techniques are summarized in the schematic phase diagram of Fig. 1 for the specic case of Pluronics L64, a well-studied block copolymer system.…”
