Sankaran, Balasubramanian published the artcileSynthesis, emission and spectro-electrochemical studies of bithienylnaphthalene systems, Application of 1,5-NAphthalenebis(trifluoromethanesulfonate), the publication is Synthetic Metals (2001), 123(3), 425-433, database is CAplus.
Four bis(2-thienyl)naphthalene monomers were synthesized and their absorption, emission and redox properties were studied. The monomers 1,5-dimethoxy-2,6-bis(2-thienyl)naphthalene (2,6-BTDMN), 1,5-dimethoxy-4,8-bis(2-thienyl)-naphthalene (4,8-BTDMN), and 1,4,5,8-tetramethoxy-2,6-bis(2-thienyl)naphthalene (2,6-BTTMN) were synthesized by Stille coupling reaction between the resp. dibromides and 2-(tributylstannyl)-thiophene. The monomers 2,6-bis(2-thienyl)-naphthalene (2,6-BTN, previously prepared from dibromo precursor) and 1,5-bis(2-thienyl)-naphthalene (1,5-BTN) were prepared similarly between the corresponding di-triflates and 2-(tributylstannyl)thiophene. Monomers 1,5-BTN and 4,8-BTDMN have only one peak in both absorption and emission spectra, while monomers 2,6-BTN, 2,6-BTDMN, and 2,6-BTTMN show multiple bands for absorption and a single doublet for emission. The oxidation potential is 0.95 V for 1,5-BTN and 0.59 V for monomer 2,6-BTTMN. Electrochem. polymerization of the monomers, with the exception of 2,6-BTTMN which was obtained by oxidative polymerization using FeCl3 as oxidant, produced good polymeric films on ITO coated glass electrodes. The polythiophenes are pale greenish in color in the oxidized state and relatively transparent and pale yellow in the reduced state. Spectro-optoelelectrochem. studies revealed a band gap of 2.4-2.9 eV. Iodine-doped poly(2,6-BTTMN) has a conductivity of 5×10-2 S/cm.
