Evidence of Heteroepitaxy and Solid Solutions in Lattice Matched Ternary Covalent Organic Framework Systems
Covalent organic frameworks (COFs) are crystalline, porous materials with the possibility for broad applications, but their structural diversity remains constrained by simple net topologies, limiting ...

Alena's and Juliane's paper is now out! By matching linker sizes we could show that disordered mixed ternary phases form, as well as molecularly defined heteroepitaxial interfaces between COFs. @jacs.acspublications.org

If you ever decide you want to make a COF for the first time, this one should be your first try. It is somewhat known in the community, but you will not really learn this from the literature this COF system is one of the most robust, in terms of synthesis and activation conditions.
