The photochemistry of 10,H,10′H-bianthrylidene was extensively studied over a wide temperature range. Two photoisomers, C and E, are formed, both reverting thermally to the parent modification A. The C isomer is a cyclization product of the 4a,4b-dihydrophenanthrene type, whereas the E isomer results from cis–trans-isomerization about the central double bond together with additional torsions about
