Abstract

Two planarized analogues of the prototypical Blatter radical (1), peri-annulated 1_Sand 1_O, 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 1_S. Magnetization studies revealed nearly ideal paramagnetic behavior at high temperatures for both radicals 1_Sand 1_Owith one-dimensional ferromagnetic interaction in the former (2J=14.4 cm⁻¹) and antiferromagnetic interactions in 1_Oat low temperatures.
