“…S7A †) was compared to the IR spectra of the thinner brushes obtained in nitromethane (140 nm) and dry chloroform (170 nm) ( Fig. 50 Unfortunately, pendant thiophene rings in the formed PMTM brushes could not be polymerized by the proposed electrochemical approach due to low reactivity as it was noticed by the authors. It was found that the average conjugation length was the largest for the 140 nm brush obtained using polymerization in nitromethane (see Fig.…”

Conductive polythiophene-based brushes grafted from an indium tin oxide substrate were fabricated as promising materials with directional conductivity for potential optoelectronic applications. The obtained brushes, thanks to their ordered structure and large conjugation length, exhibited high conductivity after chemical doping. Surface-initiated photoiniferter mediated polymerization of a 3-methylthienyl methacrylate monomer was used in the first step of grafting enabling formation of dense brushes. In the second step a self-templating approach that utilized oxidative polymerization of the pendant thiophene groups in the grafted multimonomer chains was used for the formation of ladder-like conjugated brushes. The polymerization conditions were optimized towards the largest possible effective conjugation lengths of the macromolecules. The rate of the undesirable spontaneous iodine dedoping process was followed for the first time using conductive atomic force microscopy. UV-VIS and grazing angle IR spectroscopy were applied to find correlations between various synthetic procedures and the conjugation lengths of the brushes. † Electronic supplementary information (ESI) available: Additional results of AFM measurements, grazing angle IR spectra, UV-VIS spectra, XPS spectra, estimations of the brush conductivity and a movie showing C-AFM images changing in time.

“…Most importantly, the delamination of the polymer layer from the surface can be eliminated. Very recently, Saha et al [43] reported the grafting of poly(terthiophene methyl methacrylate) (PTTMM) and poly(3-methylthienyl methacrylate) (PMTM) from gold and indium tin oxide (ITO) substrates via surface-initiated ATRP (Scheme 4). Moreover, the pendant terthiophene groups in PTTMM were electrochemically cross-linked to produce a conjugated polythiophene network.…”

In contrast to conventional main-chain conjugated polymers, incorporation of electronically active conjugated oligomers into non-conjugated polymer backbones as pendant groups represents a promising alternative strategy to developing novel electroactive polymer materials that are desirable for potential applications in organic electronics. This review focuses on polymers with thiophene in the side chain and summarizes the most important synthetic approaches to these polymers, including direct controlled polymerization techniques (e.g., ATRP, ROMP, and RAFT) as well as post-polymerization modifications. Additionally, various properties and applications of these polymers are discussed.

“…The hydroxyl function was also obtained by aldehyde reduction. In this way, methyl alcohol was obtained either in position 3′ [ 148 , 276 , 277 ], in position 3 [ 278 ], or in position 3 and 3″ [ 279 ], affording asymmetrical or symmetrical trimers with the alcohol group on the lateral units. An example of asymmetric trimer carrying alcohols on the lateral units is given by the works of the van Esch’s group, where the –OH terminated poly(ethylene glycol) chains are connected in position 3″ and 4 [ 280 , 281 ].…”

“…The alcohol [ 250 , 253 , 273 , 274 , 275 , 277 , 364 , 365 , 368 , 369 ] or the carboxylic acid [ 302 , 343 , 344 , 346 , 347 ] on the trimer is exploited for this purpose ( Scheme 19 , I and II). In this way, several molecules, nanoparticles and other functional materials were covalently linked to the trimers, including spyropyran [ 343 , 370 ], gold nanoparticles [ 371 ], poly(ethylene glycol) [ 302 , 372 ], cellulose [ 373 ], methaclyate [ 277 ], thiocarbonylthio derivate useful for RAFT (Reversible addition−fragmentation chain-transfer) polymerization [ 275 ] and olefin dendrons [ 374 ]. Numerous works report the preparation of the 3′,4′ trimer diester ( Scheme 19 , III) [ 242 , 361 , 362 , 366 , 375 , 376 ].…”

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.
