Compounds with an unpaired electron, known as radical species, are currently being synthesized to have increased stability. This research has been focused on synthesizing an organic stable radical with luminescent properties built-in to the backbone of the molecule. The target compound, (tris[4-(3,5-dichloro)pyridyl]methyl radical), seeks to balance both properties of chemical stability and luminescence. The intermediate product, bis[4-(3,5-dichloro)pyridyl]methanol, has been obtained through nucleophilic substitution of 3,5- dichloropyridine to 3,5-dichloro-4- pyridinecarboxaldehyde at 31% yield. The mesylation of the intermediate product to bis[4-(3,5-dichloro)pyridyl]methyl methanesulfonate has been achieved at 50%. Another nucleophilic substitution of 3,5- dichloropyridine to bis[4-(3,5-dichloro)pyridyl]methyl methanesulfonate, produced the precursor molecule. Future work includes forming the radical species and characterizing its stability and luminescent properties. As the synthesis of this compound continues,  the aim is to expand upon current design principles used for stable organic radicals in combination with luminescent characteristics.<br/>
