2-Bromo-5-dodecylthiophene is an organic compound that has been used as a dopant in liquid crystal devices. It is soluble in benzene, chloroform, and carbon tetrachloride. The temperature transition of this compound is between -10°C and -35°C. 2-Bromo-5-dodecylthiophene has an anthracene structure with a mesomorphic phase between room temperature and -10°C. This material displays optical activity and can be observed using optical microscopy techniques such as bright field, dark field, polarized light microscopy, and optical coherence tomography. Diffraction from 2-bromo-5-dodecylthiophene shows the presence of dodecane rings at the molecular level. Ferroelectric properties are also exhibited by this material when it undergoes a phase transition to its helical form at around -14°C to -18
