Regioselective bromiantion of naphthalenetetracarboxylic dianhydride and synthesizing its derivatives for DNA binding studies

Abstract

Functional p-conjugated organic systems have drawn considerable attention owing to their numerous applications in wide areas ranging from electronics to biomedicine.1 Rylene tetracaboxylic diimides shown in Figure 1.1 are class of robust polycyclic aromatic molecules with excellent thermal and oxidative stability, high electron affinities, high electron mobilities and therefore, promising candidates for a variety of organic electronics applications.1 Interest in rylene diimides such as those based on benzene and naphthalene stems, arrived from early observations of electron transfer behavior and the ability to tune molecular electronic properties by well-established organic chemistry protocols, either through variation of substituents on the imide nitrogen atoms or on the rylene skeleton.
