Tunable NLO activity: The title compounds were efficiently assembled from the enantiopure and threefold-symmetric tris(4-pyridylduryl)borane ligand L through coordinative bonds. Cd–organoboron framework (see picture) exhibits a significant second harmonic generation response and, more importantly, activity can be tuned by means of different encapsulated counteranions.
