Metal–Organic Frameworks as Programable Platforms for Micro‐ and Optoelectronics: From Dielectrics to Semiconductors and White‐Light Emitters

Small Science, Volume 6, Issue 6, June 2026.
Programable metal–organic framework (MOF) architectures are revealed as versatile micro‐ and optoelectronic platforms, spanning low/high‐κ dielectrics, semiconductive frameworks, and electrically driven phosphor‐free white emitters. Metal nodes, π‐conjugated linkers, guests, and confined water emerge as decisive handles for tuning charge transport ...
