Narrowband Macrocycles: A New Paradigm for High‐Color‐Purity Organic Light‐Emitting Diodes

FlexTech, Volume 2, Issue 1, Page 34-43, June 2026.
This graphical abstract illustrates two key strategies for constructing macrocyclic multi‐resonance (MR) emitters for high‐performance OLEDs: (1) the covalent assembly of MR moieties onto macrocyclic scaffolds, and (2) the local multi‐resonance strategy within the macrocyclic backbone.
