Abstract:
Well-known simple molecules such as diphenylethylene (DPE), dithienylethylene
(DTE), and tetraphenylethylene (TPE) show interesting optical properties; for instance,
TPE has been extensively studied because of its tunable luminescent properties and
some of its derivatives show aggregation-induced emission (AIE).
The corresponding thiophene based system: tetra-(2-thienyl)-ethylene (TTE), also giving
AIE, has not been as widely studied as TPE, but it and the peculiar electronic properties of
the thiophene ring make it much more appealing than TPE for applications in photovoltaics
and optoelectronics, both in itself and as building block in wider -conjugated systems.
Moreover, regioselective functionalization of the thiophene rings in TTE could afford a
wide target-oriented modulation of the scaffold properties. A few TTE derivatives had been
reported, but no systematic investigation of the structural and electronic features of the
thienylethylene class was available. Extension of the study to other heteroaromatic rings,
such as the furane based ones, was also overdue. To fill these gaps, we have performed an
electrochemical study, supported by spectroscopic experiments, on the aryl- and
heteroarylethylene molecules shown in Figure, most of them new, synthesized by us
according to an advantageous synthetic pathway. [1]
Our exhaustive investigation now affords a detailed rationalization of the redox properties
and electrooligomerization ability in this promising class of organic semiconductors, to be
exploited for target-oriented molecular design optimization.
