Owing to their unique structural and redox properties, the anthraquinoid type of π-extended tetrathiafulvalene (referred to as TTFAQs) and their D-A functionalized derivatives have offered promising prospects in modern organic electronic and optic materials. This thesis primarily summarizes the research of a series of novel functionalized TTFAQ derivatives, including a series of novel dumbbell-shaped C₆₀-TTFAQ-C₆₀ triad molecules and various donor/acceptor substituted TTFAQ systems. Electronic and optical properties of these compounds were studied by cyclic voltammetry (CV), UV-vis absorption, and fluorescence spectroscopy, and detailed oxidation state spectroscopic properties of the TTFAQ based donor/acceptor systems were characterized. These data contributed to establishing a clear structure-property relationship for these novel TTFAQ compounds, and was also informative to further investigation on their photophysical behavior and photovoltaic applications. In addition, some exploratory investigations on a TTFAQ-cored conjugated molecular switch and a one-pot synthetic strategy for rapidly preparing complex butadiynylene centered systems are reported.
