The chemistry of superacids has developed in the last two decades into a field of growing
interest and importance. Now available in a new expanded second edition, this definitive …

Ionomers, which are used as polymer electrolyte membranes as well as catalyst binders in
membrane electrode assemblies, are a key component of electrochemical energy …

Traditionally, alkaline water electrolysis (AWE) uses diaphragms to separate anode and
cathode and is operated with 5–7 M KOH feed solutions. The ban of asbestos diaphragms …

A reliable and practical approach is offered for the two critical fundamental challenges that
remain in step-growth polymerization: synthesis of narrow polydispersity and ultrahigh …

Complementary theoretical and experimental studies of the consecutive steps of superacid
catalyzed polyhydroxyalkylation reactions have been carried out. Calculations for the …

A new generation of confined palladium (II) catalysts covalently attached inside of porous
organic polymers (POPs) has been attained. The synthetic approach employed was …

We describe the synthesis of N-sulfonated poly (arylene-oxindole) by metal-free superacid,
denoted IDB, IBP, and IFP by polycondensation of isatin with 1, 4-diphenoxybenzene …

Proton exchange membranes (PEMs) play a critical role in many electrochemical devices
that could solve the shortcomings of current energy storage and conversion systems …

Hyperbranched polymers (HBPs) are highly branched macromolecules with 3-dimensional
globular structures, which have unique properties, such as low viscosity, high solubility, and …

A novel series of linear, high-molecular-weight polymers was synthesized by one-pot, metal-
free superacid-catalyzed reaction of isatins (1a− d) with linear, nonactivated, multiring …
