Organic cations, complexation

Persistent Organic Cationic Complexes Structure and Reactivity... 

Recent results obtained by the authors and their co-workers in the field of organic cationic complexes generated under stable ion conditions are discussed. Complexes with C- and N-centered electrophiles are considered. 

By employing modem physical methods and quantum-chemical calculations, a significant body of data concerning the structure and reactivity of organic cationic complexes has been accumulated during the past decade and further studies on this dynamic area of organic chemistry are currently underway in our laboratoiy. 

In NF, it is also charge and sieving that are important. While in MF colloid interactions and in UF organic interactions are important, in NF it is the speciation, ion dissociation, organic-cation complexation, as well as the structure and size of compound that have a significant impact on rejection. Solute-solute interactions of decreasing size scale are determining rejection as membrane pore size decreases. 

In 2002. Abraham published an extensive review of organic cation complexation by caiixarenes.
