Low‐lying p vacancies of the beryllium atoms inserted in 1,8‐di(BeX)naphthalene (X=H, F, Cl, CN, CF 3 , C(CF 3 ) 3 ) frameworks confer on these derivatives enhanced anion affinities that surpass those of some of the strongest neutral single Lewis acids reported. This enhanced ability to bind anions permits these compounds to be considered as good anion receptors and sensors, and therefore they can be candidates for a wide range of applications in the development of new electronic devices.
