Amino(oligo)thiophene dyes useful for studying the electrophysiology of organelles, cells, and tissues are described. Compared to previously known dyes, the amino(oligo)thiophene dyes exhibit improved (faster) response to membrane potential changes, as well as the ability to be excited by 1064 nanometer femtosecond pulses. Methods of preparing the amino(oligo)thiophene dyes are also described.
carboxaldehyde. Side chains on these fluorophores impart a strong affinity for biological membranes. Compared with benzene analogues, these thiophene fluorophores show significant red shift in the absorption and emission spectra, offering compact red and near-infrared emittingfluorophores. More importantly, both the fluorescence quantum yields and the emission peaks are very sensitive to various environmental
