# Hydroxyl-terminated dendrimers with sulfonimide linkers as binders for metals of industrial significance

## TL;DR

This paper explores the use of hydroxyl-terminated dendrimers to bind metals important in industry and the environment.

## Contribution

The study introduces new hydroxyl-terminated dendrimers with sulfonimide linkers for selective metal binding.

## Key findings

- Dendrimers effectively bind Fe3+, Al3+, and UO22+ with industrial relevance.
- Dendrimers show selectivity for Fe3+ in mixtures with Al3+.
- Dendrimer synthesis was confirmed using a 1,3-diaminopropane core and sulfonimide linkers.

## Abstract

First- and second-generation hydroxyl-terminated dendrimers were prepared starting from a 1,3-diaminopropane core and sulfonimide linkers. A first-generation mesitylene-derived dendrimer was also prepared with the same terminals. The dendrimers were then reacted with Fe3+, Al3+, and UO22+ separately in order to apply the dendrimers for binding these metals, which have important industrial applications and pose environmental problems simultaneously. The prepared dendrimers were also shown to bind Fe3+ selectively from mixtures with Al3+.
