Nanocomposite Polymeric Materials Based on Butyl Rhodamine BIncorporated in Mesoporous Films of High-Density Polyethylene

Preparation and properties of photoactive polymeric materials based on mesoporous matrices of high-density polyethylene and Butyl Rhodamine B are described. The above materials are characterized by well-pronounced fluorescence response, and its intensity is controlled by pore dimensions of the mesoporous matrix and by the presence of highly viscous inert additive (dioctyl phthalate) at fixed porosity and dye concentration. Upon interaction with heavy anions (iodine), fluorescence quenching of the sensing additive takes place.
