“…Absorption spectra of 1-6 9,26,[32][33][34][35] were obtained in MCH and are summarized in Table 1. The fusion of one thiophene ring on the f-bond of benzothiophene (1) results in a 38 (30) nm bathochromic shift of the longest wavelength absorption band of 3 (4).…”

Six aromatic compounds with embedded thiophenes differing in the number of rings (2-5) and thiophene orientation along the long axis of the molecule (syn, anti) were investigated. Photophysical properties, steady-state absorption, fluorescence, phosphorescence, lifetimes, quantum yields, and a comprehensive time-resolved spectroscopic analysis (femtosecond and nanosecond transient absorption spectroscopy) have been studied as a function of molecular structure.

“…24 The molar decadic extinction coefficient of 2 is 3-5-fold higher than that of 6a in the spectral region between 300 and 350 nm. 25,26 Since we irradiate at 300 nm and the most efficient product formation occurs when 2 is used in excess, we deduce that 6a is the reactive species in the photoreaction. Alternatively, 2 and 6a might form an excited-state complex, but this assumption has to be investigated further.…”

Photoaddition Reactions of Acetylene and Butadiyne Derivatives to Benzodithiophene^,¹

The photochemical [2pi +2pi] cycloaddition of dimethyl acetylenedicarboxylate to benzo[1,2-b:4,5-b']dithiophene has been used to synthesize substituted cyclobuta[b]thieno[2,3-f][1]benzothiophene. The first [2pi + 2pi] photocycloaddition reaction of a series of butadiynes to benzodithiophene is reported to yield regioselective and acetylene-substituted cyclobutene derivatives containing an aromatic thiophene moiety.
