Tris(2,3,5,6-tetrathiaaryl)methyl radicals, so-called tritylradicals, are emerging as spinlabels for distance measurements in biological systems based on Electron Paramagnetic Resonance (EPR). Here, the synthesis and characterization of rigid model systems carrying either two or three trityl moieties is reported. The monofunctionalized tritylradicals are connected to the molecular bridging scaffold
