Abstract:

Due to their great advantages over conventional Inorganic luminescent molecules, i.e. facile and economical processing, easy modification of the desired properties etc, Organic luminescent molecules are finding widespread use in modern day’s science and technology in search for more efficient and environment friendly functional materials. The highly fluorescent nature of various conjugated derivatives of 2,1,3-benzoxadiazole, more specifically known as benzofurazan, have been mainly utilized in designing various fluorogenic precolumn labeling reagents for amino acids analysis and heavy metals detection. However contrary to its Sulfur containing analog, i.e. 2,1,3-benzothiadiazole that is exhaustively utilized in solar cells, semiconductors, liquid crystals and conjugated polymers, the benzofurazan derivatives are rarely reported for such kind of applications. In this work we present syntheses and photophysical properties of some rationally designed derivatives of benzofurazan with extended conjugation and their potential use in OLEDs
