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
