Rose bengal poly

TABLE 3.8 Photodynamic inactivation of microorganisms on the surface of paper treated with conjugates of Rose Bengal (RB) and Phloxine B (PhB) with poly (vinyl amine) (PVAm) (adapted from Brovko et ai, 2009)... 

Silica gel as a support for Rose Bengal was reported by Tamagaki, Liesner, and Neckers [303], A similar system had been reported previously with the sensitizer methylene blue [304], Rose Bengal immobilized to poly(2-hydroxyethyl methacrylate) has also been reported by Schaap [305],... 

This excited state hasn t the energy to abstract hydrogen from a Merrifield poly(styrene-co-divinyIbenzene) backbone. Rose Bengal triplets are completely quenched by oxygen at concentrations over 10 m. 

The immobilization of rose bengal to non-crosslinked poly(styrene-co-chloromethyIstyrene) is shown for a 3 1 co-polymer with differing concentration of rose bengal in Table HI.

Protonated poly vinylpyridine (PVP) coated on Nesa glass bound rose bengal electrostatically. This modified electrode, when dipped into an aqueous solution containing a redox reagent such as Fe, induced an anodic photogalvanic effect A photo-... 

Using a dendritic box which was constructed from a flexible poly(propyleneimine) dendrimer with 64 amine end groups and an L-phenylalanine derivative (Fig. 6.7) as host and Rose Bengal andp-nitrobenzoic acid as two guests with different sizes, Meijer et al. demonstrated shape-selective liberation of guests from dendritic boxes (Fig. 6.8) [25]. Four molecules of... 

Recently, we are also able to perform liquid-liquid extractions of water-soluble dyes from water to organic solvents like toluene using the unimolecular dendritic micelles as extractants. These guest-host properties of the modified poly(propylene imine) dendrimers make use of the basic nature of the interior of the dendrimer. Therefore, it is possible to transfer dyes like Bengal Rose into toluene. Although simple tri-octylamines are capable of transferring these dyes as well, it is evident from the experiments that unimolecular dendritic inverted micelles are much more selective, probably due to the shielding effect of the apolar shell [70].
