Description	The synthesis and optical properties of three new fluorescent alkoxy-substituted thieno[3,2-b]indole (TI) derivatives, including 7-methoxy thieno[3,2-b]indole (7-MeOTI), 6,7- methylenedioxythieno[3,2-b]indole (6,7-MDTI) and 6,7-dihexyloxythieno[3,2-b]indole, (6,7-DHTI), were investigated. Electronic absorption spectra, fluorescence excitation and emission spectra, fluorescence quantum yields (Phi(F)), lifetimes (tau(F)), and other photophysical parameters of the three TI derivatives were measured in DMSO solutions at room temperature. Theoretical electronic absorption and fluorescence spectra were also calculated by means of a molecular orbital (MO) method. For all three alkoxy-TI derivatives, the fluorescence emission maximum wavelength was significantly red shifted relative to un-substituted TI, which was attributed to delocalization of the fused hetero-aromatic ring pi electronic system by the electron-donating alkoxy group(s). Phi(F) values varied from 0.12 to 0.19, according to the compound. tau(F) were short, in the range 0.56-1.13 ns. (C) 2013 Elsevier B.V. All rights reserved.
