Photocatalytic disassembly of tertiary amine- Q1 Q2 based dendrimers to monomers and their application to the ‘catch and release’ of a dye in aqueous solution

Sharma, Anindra ; König, Burkhard ; Jayaraman, Narayanaswamy



Abstract

Photocatalytic dis-assembly of tertiary amine-based poly(propyl ether imine) dendrimers, in the presence of either 9,10-anthraquinone or riboflavin tetra-acetate and O2 leads to di- and tripropanolamine monomers. An application is shown by solubilisation of a water-insoluble sudan I in aq. dendrimer solution (‘catch’), followed by its ‘release’ upon dis-assembly of the dendrimer.
