. SCSD analysis of the central anthracene core of the tetrabenzopentacene derivative in CCDC: WUHTUO. These are, of course, among the most distorted examples, and compounds 1.3-1.5 have a nonanthracene electronic core, so would present non-anthracenoid photochemistry. From this data, we can however preview the modes of distortion applicable to a small unit may be inherited when composing part of a larger molecule, giving some indication of local curvature in an extended system. This approach is being investigated.
