Two planarized analogues of the prototypical Blatter radical (1), peri-annulated 1Sand 1O, are demonstrated and provide a new platform for molecular and supramolecular engineering, and for tuning electronic and magnetic properties of the radical. Planarization of 1 results in bathochromic shift to the near-IR region, greater spin delocalization, and anodic shift of the reduction potential only for 1S. Magnetization studies revealed nearly ideal paramagnetic behavior at high temperatures for both radicals 1Sand 1Owith one-dimensional ferromagnetic interaction in the former (2J=14.4 cm−1) and antiferromagnetic interactions in 1Oat low temperatures.
