Special Issue Chemistry at the Interface
Frank H. Quina
How to cite this articleThe modulation of reactivity by interfaces is of fundamental importance in chemical and biochemical systems. The pseudophase assumption coupled with ion selectivity at the interface are sufficient to reproduce (as well as predict) many of the effects of simple ionic detergent micelles on chemical reactivity. These concepts illuminatethe underlyingrelationships betweenchemical and photochemical reactivity and the structural and electrostatic properties of charged interfaces. Details are presented in the Review Modeling Chemical Reactivity in Ionic Detergent Micelles: a Review of Fundamentals by Frank H. Quina on page 267.

Water with excess charge is the outcome of many different events triggered by electric fields or by interfacial phenomena that produce non-electroneutral water, either liquid, solid or vapor, due to excess H+ or OH- concentration.

Aquo[N,N'-bis(salicylidene)-o-phenylenediamine]zinc(II) ([Zn(salophen)(OH)2]) exhibits low photoluminescence (PL) and electroluminescence (EL) properties. However, due to the high energy transfer and charge recombination from the poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-co-(9,9-di-{5'-pentanyl}-fluorenyl-2,7-diyl)] (PFOFPen) blue luminescent polymer, [Zn(salophen)(OH)2] exhibits an intense EL, combining polyfluorene and coordination compounds, and generates a near-white light organic light-emitting diode (OLED).
