Electronic structure of the boron nitride rings and fullerene-like BN-molecules (the fulborenes) are calculated using MNDO, AM1, Extended Huckel, INDO and ab initio (STO-3G) methods. The fulborene B⁶⁰N⁶⁰ is confirmed as the boron nitride analogue of buckminster-fullerene C⁶⁰. Comparisons with other calculations are presented and possible applications as nanoporous materials and photonic crystals are discussed.
