Title	The Synthesis and Spectral Properties of Conjugated Dye Systems
Advisor	Connors, Robert E., CH

Abstract In this MQP, the synthesis and spectral properties of a conjugated dye, namely 1, 9-bis-(p-dimethylamino)-nonane-1,3,6,8-tetraene-5-one, or 2dbmac, were explored. The electronic absorption and fluorescence properties were examined in various nonpolar and polar solvents. In addition to the electronic absorption and fluorescence properties, fluorescence quantum yields and fluorescence lifetime parameters were explored. Upon calculating the fluorescence quantum yield and fluorescence lifetime parameters, first-order radiative and nonradiative rates of decay were calculated. Lastly, quantum chemical calculations were performed on the compound.
