Abstract

A new family of dimeric B/N Lewis pairs with sterically tunable substitutions has been accomplished using the Two-in-One design strategy. Their structures are characteristic of doubly B/N-containing cores, and the electronic interactions between B and N centers can be modulated by the steric effects of ortho-substitutions from methyl groups. Interestingly, unique white-light emissions were achieved for 2M'2BNM and 1M2BNM, ascribed to the integration of two triarylborane species (B_sp²- and B_sp³-hybridization) into one single molecule.
