Physicochemical characteristics of reverse micelles of polyoxyethylene nonyl phenol in different organic solvents

3,4,9,10‐Perylenetetracarboxylic Acid Derivatives, Their Spectral Behavior and Their Chemical Interaction with Hydrated Iron Oxide Nanopar

“…20 Fluorescence quenching of photosensitive dyes by neutral or charged species in organized assemblies has been frequently studied in order to characterize the medium. 21 In the present study, we report the photophysical properties and laser activity of some new perylene derivatives namely, N,N-bis(pyrimidenyl) -3,4,9,10-peryl-enetetracarboxylic diimide (PmPBD), N,N-bis(pyridenyl)-3,4,9,10-perylenetetracarboxylic diimide (PyPBD) and N,N-bis(4-methylpyridenyl)-3,4,9,10-perylenetetracarboxylic diimide (MPyPBD). The interactions of metal ion as Co 2＋ ion and hydrated iron oxide nanoparticle with perylene derivatives are also investigated.…”

Self-assembly of cetylpyridinium chloride in water–DMF binary mixtures: A spectroscopic and physicochemical approach

“…To carry up the details of the interaction involved in the solvophobic effect, many investigations have carried out where water is partially replaced with another polar solvent [6][7][8][9]. Cetylpyridinium chloride (CPyCl) is a versatile cationic surfactant and frequently used in several applications, including chemical and biophysical studies [10,11].…”

Substituent effect on the emission behavior of thiazolidinedione derivatives in cationic and anionic micellar media

“…The knowledge of the structure of the micelles, the local environment, the local concentration and the relative orientation of the solubilized molecules is of fundamental importance in understanding the nature of the solubilization and the physical and chemical behavior of the solubilized species [6,7]. Micelles, which are used as membrane biomimetic agents, gain importance by virtue of their capacity to provide a matrix for arranging the reaction sequentially for efficient interaction, i.e., they help in compartmentalization of the reactants dynamically [8][9][10][11][12][13][14][15][16][17]. Water molecules, which are tightly bound to the surfactant head groups of micelles, resemble the hydrophilic pockets of enzymes and have high viscosities, low mobilities and polarities [18,19].…”
