“…Various trimer carboxylic acids have been prepared, directly connected to the thiophene rings [ 342 , 343 , 344 , 345 ] or linked through a spacer. In fact, spacers of one [ 346 , 347 , 348 , 349 , 350 , 351 , 352 ], two [ 279 , 353 , 354 ], three [ 355 ], four [ 354 ], five [ 356 ] or six [ 350 ] carbon atoms are reported ( Scheme 18 , I and II). Benzoic acid, connected in para on position 3′, is also reported ( Scheme 18 , III) [ 249 , 357 ].…”

“…Therefore, common precursors of carboxylic acid trimers are 3-thiophenecarboxylic acid and 3-Thiopheneacetic acid. Thiophene aldehyde can be converted to α,β-unsaturated carboxylic acid by aldol condensation [ 279 , 354 ]. Furthermore, in order to avoid the esterification and the hydrolysis steps, in some works the carboxylic acid is obtained by hydrolysis of nitrile [ 313 , 342 , 345 ].…”

Certainly, the success of polythiophenes is due in the first place to their outstanding electronic properties and superior processability. Nevertheless, there are additional reasons that contribute to arouse the scientific interest around these materials. Among these, the large variety of chemical modifications that is possible to perform on the thiophene ring is a precious aspect. In particular, a turning point was marked by the diffusion of synthetic strategies for the preparation of terthiophenes: the vast richness of approaches today available for the easy customization of these structures allows the finetuning of their chemical, physical, and optical properties. Therefore, terthiophene derivatives have become an extremely versatile class of compounds both for direct application or for the preparation of electronic functional polymers. Moreover, their biocompatibility and ease of functionalization make them appealing for biology and medical research, as it testifies to the blossoming of studies in these fields in which they are involved. It is thus with the willingness to guide the reader through all the possibilities offered by these structures that this review elucidates the synthetic methods and describes the full chemical variety of terthiophenes and their derivatives. In the final part, an in-depth presentation of their numerous bioapplications intends to provide a complete picture of the state of the art.

“…This monomer was potentiodynamically electropolymerized to form films on the surface of a glassy carbon electrode (GCE) and an Au electrode of a QCR for electrochemical impedance spectroscopy (EIS) and PM transduction, respectively (Table 2). Neutravidin was irreversibly Microstructural changes of films of terthiophene functionalized with acrylic acid (PTAA) [141] or with pentadienoic acid [142] have been examined (Scheme 15). The microstructure of both films was sustained in organic solvents, but collapsed in aqueous buffer solutions.…”

“…[3',3'''-bis(hydroxymethyl)-2':2'',5'':2'''-(terthiophene)-3''-yl]acrylic acid (HTAA), was synthesized (Scheme 15)[144] to mitigate the PT microstructure collapse in aqueous solutions[141,142]. Indeed, this collapse was significantly diminished compared to that of the previously prepared terthiophene polymers.…”
