Spectroelectrochemistry of 2,5,8,11-tetra-tert-butyl-peri-xanthenoxanthene 1 yields the UV/VIS spectra of the corresponding radical cation 1(.+) and dication 1(2+). The bathochromic shift for the dication 1(2+) relative to 1 and to the isoelectronic hydrocarbon anthanthrene (2) can be understood by quantum mechanical calculations (ab initio, AM1) of model structures.
