conditions, a further negatively shifted oxidation onset potential
at 0.04 V can be observed for isomer 6c which exhibits two
reversible redox couples with half-wave potentials of 0.11 and
0.39 V, respectively. Such two-step one-electron oxidations
correspond to the sequential removal of electrons from the
thiopyran moieties to form the stable radical cation and dication.
Moreover, unlike isomers 6a and 6b, the CV curves of 6c overlap
very well during repetitive cycling, which implies that its
oxidized states are extremely electrochemically stable.
In summary, an unexpected ring-expanding cycloaromatiza-
tion of cyclopenta[b]thiopyran from 1-acetyl-2-thienyl deriva-
tive catalyzed by PtCl2 was developed. From an identical
precursor, three rigid and planar S-heteroarene isomers were
successfully synthesized. Interestingly, the three resulting
isomeric S-heteroarenes demonstrated completely different
photophysical and electrochemical properties. The NIR
absorption, relatively low oxidation potential, and the excellent
electrochemical stability will make aromatic cyclopenta[b]-
thiopyran derivatives as promising building blocks for organic
semiconductors with unique properties. Our ongoing work is
focused on the expansion of the substrate scope and their further
applications in optoelectronics.
