“…The lower ionization potential of selenium leads to a polymer that has a lower band-gap (1.6 eV) than polythiophene. [26][27][28] The greater mass and polarizability of selenium is also expected to lead to improved charge transport characteristics. So far, polyseleophenes have similar hole mobilities, but improved electron mobilities when compared to polythiophenes.…”

Will polytellurophenes bridge the gap between conjugated polymer and inorganic solid-state semiconductors? Polytellurophenes are a virtually unexplored class of conjugated polymer. In this paper, the synthetic methodologies that have been used to prepare polytellurophenes are chronicled. The properties of the resulting polymers are discussed and their potential for use as electronic materials is evaluated. It is far too early to know if these materials will lead to a useful class of thin-film semiconductors, however some key challenges associated with their synthesis and implementation are outlined. These challenges will need to be addressed as the conjugated polymer research community begins to utilize this area of the periodic table.

“…In situ electropolymerization provides access to uniform polymeric films on conductive substrates with tunable morphologies and thicknesses [271]. However, over the past few decades, electropolymerization has been limited to applications such as electrochromism and conductive films where ion-doping is required [272][273][274][275][276]. Indeed, non-quantitative unlimited electrochemical coupling reactions usually lead to conducting conjugated polymers with high doping states.…”

No. of Pages 30 2 G. Rydzek et al. SummaryDuring the last few decades, electrochemistry and electrode modification have seen a tremendous fall off in creativity with the emergence of the nanoarchitectonic-based layerby-layer (LbL) film deposition technique. An unprecedented variety of building blocks can be immobilized on surfaces, leading to progress in several fields including sensing, electrochromic, electro-responsive and energy devices. This review describes the state of the art of electrochemical devices based on LbL assemblies, with a focus on supercapacitors, biosensors, and electroresponsive LbL such as electrodissolution/electroswelling of coatings. Recently, electrochemistry has also been used as an ''active trigger'' to induce the formation of films by covalent coupling, leading to new nanoarchitectonic approaches beyond the LbL strategy. These emerging electro-coupling reactions, including electroclick and carbazole chemistry, open new perspectives toward architecture and patterning of functional films and are extensively reviewed.

“…Electrochromic materials have been known for many years, containing inorganic electrochromic materials [11][12] (WO 3 , NiO, et al) and organic electrochromic materials [13][14]. The organic electrochromic materials can overcome the shortcoming of the inorganic electrochromic materials, such as high costs, the long response time and the single color change.…”
