Abstract:
We have synthesized a series of tetra(2-thienyl)ethylene
(TTE) derivatives, selectively functionalized at the thiophene
α positions, either by a coupling procedure or by direct electrophilic
substitution of the TTE system. Optical spectroscopy
revealed that TTE shows orange emission (470 nm) in a diluted
2-MeTHF matrix at 77 K and blue (420 nm) aggregation-induced emission (AIE) in the solid state. An exhaustive
electrochemical study afforded a full rationalization of the
electronic properties in terms of the HOMO and LUMO energy
levels and gaps, as well as localization and features of
the redox centers with respect to TTE functionalization
