Inside Back Cover: In Situ Tandem Synthesis of Charged Boron‐Oxo Clusters into Highly Ordered Architectures (Angew. Chem. Int. Ed. 48/2025)

The synergistic combination of dynamic covalent bonding, coordination-driven assembly, and electrostatic interactions in an in situ tandem process enables the controlled organization of disordered ionic and molecular species into highly ordered architectures, allowing systematic modulation of third-order nonlinear optical (NLO) properties. This work establishes a robust synthetic approach for the rational design of boron-oxo clusters and their assembly into well-defined architectures.
