Abstract
Official abstract text for this publication.
Compounds are provided for the capture of polycyclic aromatic hydrocarbons. The compound is selected from formula (I) and formula (II): The compound includes a salt formed with a suitable counter anion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A compound salt of formula (I): and PF 6 − . 2. A separation medium consisting of the compound salt according to claim 1 . 3. A method of separating a polycyclic aromatic hydrocarbon (PAH) compound from a solvent comprising the PAH compound, comprising: contacting the solvent comprising the PAH compound with a compound salt of formula (I): and PF 6 − . 4. The method of claim 3 , wherein the solvent is selected from an aqueous or organic solvent. 5. The method of claim 3 , wherein the PAH compound consists of a planar PAH compound. 6. The method of claim 5 , wherein the PAH compound is naphthalene.
