A series of new bis-thienylanthracene derivatives D1~D5 containing 9,10-antharcene moiety in the center and 2-methylenemalonotitrile or 2-cyanoacrylic acid functional group on the terminal thiophenes were synthesized and characterized by $^1H$-NMR and high-resolution mass spectroscopy. Their optical, electrochemical, and thermal properties were measured. They have absorption ${lambda}_{max}$ in the range of 437~480 nm and max of $7.4{ imes}10^3{sim}2.0{ imes}10^4M^{-1}cm^{-1}$. The substitution of 2-cyanoacrylic acid group allows greater value of ${varepsilon}_{max}$ than that of 2-methylenemalonotitrile. TGA curves showed that D4 and D5 which have 2-cyanoacrylic acid functional group on the terminal thiophene(s) exhibit good thermal stability and D4 was thermally stable up to $400^{circ}C$. Their optical properties and LUMO energy levels measured suggest that they can serve as potential candidates for electron donor materials of organic photovoltaic cells (OPVs) or D4 and D5 which contain 2-cyanoacrylic acid group can be used as organic dyes of dye-sensitized solar cells (DSSCs).
