Synthesis of new π-conjugated heteroaromatic oligomers, such as indole, carbazole, dibenzofuran and dibenzothiophene bridged by acetylene are described in this review. Moreover, their photophysical properties investigated by means of UV-vis/fluorescence spectroscopies and comparison with those of the parent compound or any structural isomers are discussed.
