Abstract:
A systematic investigation of the reactivity and functionalization of two
heterocyclic analogs of triphenylmethane , namely tris(2-thienyl)methane and
tris(2-furyl)methane have been carried out and the results are presented in this
thesis entitled "NOVEL REACTIONS OF TRIS(2-THIENYL)METHANE AND
TRIS(2-FURYL)METHANE.". The history of organic free radicals dates back to Gomberg's monumental discovery of the triphenylmethyl radical in 1900. The heterocyclic analogs of triarylmethane are also interesting from the vantage point of their transformation to the corresponding radicals akin to Gomberg ' s triphenylmethyl radical and also they are prone to further transformation leading to three dimensionally elongated molecules such as dendrimers. Dendritic architectures are one of the most pervasive topologies observed in nature at the macro- and microdimensional length devices. Because of their ability to combine both organic and inorganic compounds and their propensity to either encapsulate or be engineered into unimolecular functional devices , dendrimers are versatile amongst existing nanoscale building blocks and materials.
