Abstract
ESR and UV investigation of synthesized diradical reveals its lifespan that extends to weeks even with the existence of oxygen. It is also found to be capable of surviving brief heating in toluene of up to about 60 degrees celsius. In a temperature that ranges from -10 to 50 degrees celsius, the diradical exhibited reversible thermochromic behavior. Meanwhile, the phenoxyl and nitroxide spin carrying units almost exhibited an isolated behavior when subjected under hyperfine analysis.
