Different synthetic routes to obtain hydrophilic matrices

Dendrimers Derived from 1 → 3 Branching Motifs

“…214 This ester triol transformation (K 2 CO 3 , DMSO, TRIS) has been demonstrated in the conversion of numerous initially nondendritic hydrophobic materials into more hydrophilic compounds: e.g., a neutral, cyclophanedodecaalcohol, 320 diverse (cyclo)alkyl 321 and benzene cores, 321,322 and lower rim polyhydroxylated calix [4]arenes. 323 Other nonionic TRISbased polyols, useful as sugar macronutrient substrates in low-calorie food formulations, have been reported by Yalpani et al 324 Alvarez and Strumia 325 studied two protocols for obtaining hydrophilic acrylic acid-ethylene glycol dimethylacrylate matrices. One of the methods included CDI-based coupling with TRIS and copolymerization of hydrophilic monomers.…”

Three steps to organic–inorganic hybrid films showing superhydrophilic properties

“…Indeed, multiple carbodiimides can be used as coupling agents to modify carboxyl-containing supports: DCC is less expensive and most widely used and is soluble in organic solvents or organicsolvent/water mixtures; EDC is a water-soluble coupling agent and has demonstrated a better effectiveness for the incorporation of a ligand with a basic amine group on a carboxyl containing matrix because of the speed and high conversion yields. 39 Moreover, as the reaction proceeds in water, it should favor the swelling of the polyacrylic acid chains and make the carboxylic groups more accessible. The reaction was thus carried out in water using EDC as coupling agent in the presence of NHS.…”
