Acceleration of the rate of alkaline ester hydrolysis by linear amphiphilic ionenes

Fusion-Fission Transport of Probes and Quenchers in Microdomains of an Amphiphilic Ionene Polyelectrolyte†

“…In aqueous solution, [n,m]-ionenes with short methylene segments, such as the [3,6]-ionene (n = 3, m = 6), adopt extended conformations and behave like typical rod-like polyelectrolytes (1)(2)(3)(4). In contrast, amphiphilic ionenes, such as the [3,22]-ionene (n = 3, m = 22), spontaneously adopt globular conformations and form microdomains that are highly micelle-like , i.e.…”

Catalysis of an Alkaline Hydrolysis Reaction by Ionenes Immobilized on Silica

“…In contrast, amphiphilic [n,m]-ionenes with long methylene segments, such as the [3,22]-ionene, prefer globular conformations, forming microdomains via intra-or inter polymeric aggregation of the long segments. [1,5,6] Because of their micelle-mimetic properties, amphiphilic [n,m]-ionenes have been shown to have a variety of applications in analytical chemistry. [7][8][9] Because the ionenes are polymers, it is possible to immobilize them on solid supports by covalent bonding or electrostatic adsorption.…”

Synthesis and Characterization of Chiral [3,22]‐Ionenes

“…Ionenes with short methylene segments, such as the [3,10]ionene, exhibit behavior typical of linear polyelectrolytes, adopting an extended rodlike conformation in aqueous solution. [5] On the other hand, ionenes with at least one methylene segment longer than 14 carbons, present polysoaps or micelle-mimetic behavior, adopting globular conformations and forming hydrophobic microdomains in aqueous solution through intrapolymeric aggregation of the longer methylenic segments of the polymer chain. [4][5][6][7] Aqueous solutions of ionenes usually have much higher surface tensions and exhibit much lower foaming than typical surfactant solutions and do not emulsify in the presence of organic solvents.…”
