The study of π-conjugated oligomers is of great interest due to their great potential use in organic electronic devices (OEDs), such as solar cells, light-emitting diodes, etc. Thiophene-containing compounds have been extensively studied because of their good stability and synthetic accessibility; however, studies on furan-containing compounds have shown that these may also be viable, and even more preferred substitutes. Furan-containing compounds show greater solubility and increased fluorescence compared to their thiophene analogues. Furan is also biodegradable and can be obtained from natural sources, making it a good choice for mass produced products. Furan compounds, however, tend to be rather unstable and possess high HOMO-LUMO gaps. In the study presented here, hybrid oligomer systems containing both furan and thiophene were synthesized and characterized using DFT methods and a number of spectroscopic methods in an attempt to determine if combing the two heterocycles could create a compound possessing the positive attributes of the two individual cycles.
