Abstract
The title dication (1 2+) was generated by oxidative bond cleavage of a 4,5-dihydoropyrene derivative (2) with two spiro(10-methylacridan) units. Despite the skewed deformation of the arylene spacer, two cationic chromophores in 1 2+ are forced to face in a proximity with a very short interatomic separation of 2.98(1) Å between carbenium centers (X-ray), which makes the LUMO level of 1 much lower than that of biphenyl-2,2′-diyl-type dication (3 2+).
