A nascent field of molecular spintronics has revolutionized the field of magnetic recording with future applications in next generation nano-electronics and information technology industry. An essential ingredient for realizing a spintronic device is the generation of spinpolarized current delivering metallic features for one spin channel and insulating for the other. Organic radicals featuring unpaired spin are ideal candidates for such components in conjunction with their rich behavior represented by Kondo signatures, magnetoresistance and shot noise resulting from spin correlations. One of the cornerstone is the transient nature of organic radicals where the stability of radical is even more questioned when interfaced with metallic substrates and conducting electrodes. The radicals moieties are typically stabilized by screening the paramagnetic center sterically or through the spatial delocalization of the unpaired electron, even though the integration of the persistent radical species to functionalize the highly conductive and stable single molecule devices has remained as a major challenge. One class of thermally robust π-conjugated radical based on 1,2,4-benzotriazinyl scaffold is Blatter's radical (shown in Figure ). The radical was first synthesized by Blatter in 1968. Later, several new synthetic strategies were developed by researchers for the easy synthesis of a library of the related superstable radicals. As described in our previous works, an extensive unpaired spin delocalization accompanied by delocalized SOMO makes the radical super-stable in nature. The spin-density distribution (shown in Figure ) reveals the unpaired electron for Blatter's radical is not only confined to three N-atoms but delocalizes across both the triazinyl and fused benzene ring. Owing to its super-stability, Rajca and co-workers designed and synthesized couple of high-spin Blatter-based diradicals, paving the way for this radical to be used in molecular spintronics. Consecutively, we also proposed several Blatter-based diradicals, based on the ab-initio calculations, with reasonably strong ferromagnetic exchange interactions. In the view of using stable radical moieties in real-devices, Blatter's radical has been recently studied in various environments involving metal-molecule interfaces. Ciccullo et al. demonstrated the possibility of using Blatter's derivative to create thin films with radical properties. In two subsequent reports, Venkataraman et al. provided a direct evidence of kondo resonance for Blatter's radical adsorbed on Au(111) substrate, while the radical character was suspected to be lost through oxidation in solution-based single-molecule conductance measurements. Later, Sadeghi and co-workers successfully synthesized stable Blatter's radical to form a single molecule junction by introducing an electron withdrawing (CF 3 ) group as a linker to prevent the oxidation of radical. Alongside, a theoretical study also claimed that Blatter's radical can unequivocally retain its open-shell nature when bound to gold electrodes irrespective of the environmental conditions. A recent magnetoresistance study on Blatter's molecular junction also confirmed the signature of the open-shell nature of the radical in a two-terminal device using dI/dV spectroscopy. More recently, such radical-based molecular electronic devices has started attracting even more interest due to continuous predictions of radical induced non-negligible enhancement of conductance (G).
