“…A third strategy has involved increasing the label content such that the luminescent species itself acts as a modifier, which subsequently creates a new class of fluorescent polyelectrolyte [20,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. Copolymers of this type, containing a high degree of aromaticity have shown potential as media for efficient light harvesting OPTICAL PROPERTIES OF POLYELECTROLYTES (i.e.…”

“…Because poly(carboxylic acid)s have received particular attention in the literature in respect of their fluorescence behavior in aqueous solution [6,12,13,[16][17][18][19][20][21][22][23][24]26,[29][30][31][32][33][34][43][44][45][46] and have been comprehensively studied by classical methods [2][3][4][47][48][49][50][51][52] , this important class of polyelectrolyte will be reviewed initially before moving on to other examples. The active repeat unit in poly(methacrylic acid) (PMAA) is the carboxylic acid function, which dissociates upon increasing pH to form negatively charged carboxylate anions.…”

“…Synthetic strategies adopted to achieve this end have included simple copolymerization of an ionizable repeat unit with a hydrophobic monomer [20,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]129] to form statistical copolymers and formation of block copolymers [71,. The switch in conformation is marked by a change in macroscopic properties, such as solution viscosity, over a narrow and characteristic pH range specific to that polymer which is important from a technological viewpoint.…”

“…The polymer is presumed to form a "pseudo micellar"-type structure with the hydrophobic light-absorbing groups forming hypercoiled domains in the interior surrounded by ionic hydrophilic units on the exterior of the "micelle" thereby promoting the antenna effect [27]. 2.11, is the basis for the complex photophysics observed in these systems [20,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]128,129] but is also the rationale behind potential applications [31,32,36,38,40,44,45]. 2.11, is the basis for the complex photophysics observed in these systems [20,[27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43]…”

“…Consequently, luminescence methodologies have enjoyed increasing exposure to such amphiphilic systems over the last two decades [20,[33][34][35]38,93,120,121,[130][131][132]173,184,185,194,[196][197][198][199][200][201][202][203][204][205][206]. Fluorescence spectroscopic techniques would appear ideally suited to probing the nature of hydrophobic association of polysoaps in aqueous media because intramolecular interactions can be examined in isolation to intermolecular effects.…”

A polyelectrolyte can be defined as a macromolecule with ionizable repeat units, which can consequently display pH-dependent behavior when dissolved in aqueous solution.As the term polyelectrolyte can also be extended to encompass natural biopolymers, which contain ionizable groups such as peptides, proteins, and DNA, it is perhaps not surprising that synthetic polyelectrolytes are often used as simple models for more complex biological systems. Indeed, many of the photophyscial techniques discussed in this chapter were developed by biologists and biophysicists interested in the conformational behavior and interactions of biopolymers [1].

Amphipathic polymers with stimuli-responsive microdomains for water remediation: Binding studies withp-cresol

Amphipathic, stimuli-responsive water-soluble polymers have been investigated as potential remediation agents for micellar enhanced ultrafiltration (MEUF). The systems represent divergent architectural types, a triblock ABA copolymer of PEO-PPO-PEO, an n-octylamide modified poly(sodium maleate-alt-ethyl vinyl ether), and the transport protein, bovine serum albumin. Each type exhibits stimuli-dependent microphase separation or domain formation in response to temperature, pH, and/or ionic strength changes. Segmental associations result in hydrophobic clusters resembling those present in small molecule surfactant micelles. The effects of such segmental aggregation on sequestration of a model hydrophobic foulant, p-cresol, have been investigated using equilibrium dialysis. The favorable molar binding values, the large hydrodynamic dimensions of the stable polymer aggregates, and potential reversibility of foulant loading could have commercial utility in high flow rate, multiple-pass remediation processes.

Water‐soluble (co)polymers represent a diverse class of macromolecules ranging from naturally occurring biopolymers such as polysaccharides and most polypeptides to wholly man‐made materials. Such materials have found a wide‐range of applications. In this article we detail the synthesis and solution characteristics of both natural and synthetic polymers. Emphasis is placed on polynucleotides, polypeptides, and polysaccharides for naturally occurring polymers, while the discussion regarding synthetic materials is divided into sections dealing with neutral, anionic, cationic, and zwitterionic species. Special attention is given to recent advances in synthetic methodologies which now allow the tailoring of synthetic materials with precisely controlled microstructures, predetermined molecular weights, narrow molecular weight distributions, and complex topologies. Finally, we detail some of the self‐assembly characteristics of both high molecular weight statistical copolymers and lower molecular weight block copolymers in aqueous media with an emphasis on those materials which undergo phase transitions and/or conformational changes in response to an applied stimulus.
