Anthracene and its dyes have gained substantial attention for a very long period of time due to their rich photophysical properties. Its derivatives are highly tunable and small changes in their substituents or π-conjugation can drastically change the optical properties. Among the ethynylanthracene based molecules, 9,10-bis(phenylethynyl)anthracene (BPEA) is a very well-known industrial dye with robust chemical and thermal stabilities and a quantum yield value of unity. BPEA and its derivatives absorb as well as emit in the visible region with high emission efficiencies. They have been widely studied and have been functionally employed in various fields such as photovoltaics, organic light-emitting diodes (OLEDS), fluorescent sensors, optical waveguides as well as in bio-applications.1,2,3 Though there are various reports regarding the syntheses and applications of the symmetrical molecules, not much have been explored about the basic photophysical properties of unsymmetrical molecules or their monosubstituted analogues. In this research proposal seminar, a brief literature review about this class of molecules, the objective to fill the gap area as well as our preliminary results will be discussed.
