Abstract

A family of metallocavitands with extended cavities of general formula {[Cp* Ta] 3 (μ2-RB (O) 2) 3 (μ2-OH)(μ2-O) 2 (μ3-OH)}(R= polyaromatic rings) has been synthesized and characterized by NMR spectroscopy and X-ray diffraction. The trimetallic species feature a large Lewis acid type cavity allowing for substrate binding in both the solid and the liquid state using a unique electrostatic interaction and a hydrogen bond. Δ H° and Δ S° values ...
