been investigated by nanosecond transient absorption spectroscopy, photoacousticcalorimetry, measurements of 1 O 2 quantum yields, and photochemical studies in solution. Both the lifetime (1.4 μs) and the energy (74-76 kcal mol -1 ) of the BNEN triplet reflect its exceptional conformational rigidity, which prohibits relaxation along the 3 (π,π * ) potential energy surface by twisting around the C=C
