An unprecedented nanoporous and fluorescent supramolecular framework with an SrAl2 topology controllably synthesized from a flexible ditopic acid

Abstract

A novel supramolecular framework was obtained from the ligand H2BDOA (benzene-1,3-dioxyacetic acid) that exhibited an SrAl2 topology with 1.7 × 1.7 nm channels formed by strong hydrogen bonds and demonstrated an interesting crystal-to-crystal transformation property.
