An Alternative Synthysis of Thieno [3, 4-b] Thiophene. Brandsma L and Verkruijsse HD.

Synth. Commun. 20(15) , 2275-77, (1990)

Synthesis and structure of alkyl-substituted fused thiophenes containing up to seven rings.

J. Org. Chem. 72 , 442, (2007)

We have established a series of synthetic methods to synthesize alkyl-substituted fused thiophenes with degrees of fusion from two to seven rings. These fused thiophene ring compounds have very good s...

Double photoionization of thiophene and bromine-substituted thiophenes.

J. Chem. Phys. 129(23) , 234303, (2008)

We report the double photoionization spectra of thiophene, 3-bromothiophene, and 3,4-dibromothiophene using a coincidence spectroscopy technique based on electron time-of-flight measurements. Spectra ...
