Translating MOF chemistry into supramolecular chemistry: soluble coordination nanofibers showing efficient photon upconversion

Abstract

A method for synthesizing coordination nanofibers by extracting the structural motifs of metal–organic frameworks (MOFs) is demonstrated. In these soluble nanofibers, multiple chromophores with largely different sizes and shapes can be arranged at desired compositions, and excited triplet energy migrates among the densely assembled chromophore arrays, showing an efficient photon upconversion even at very low concentration.
