Effect of polythiophene thickness on hybrid sensor sensitivity

Reviews on Advanced Materials Science, 2021
In recent years, hybrid structures have attracted wide consideration because they generate new very interesting properties. In this study, a hybrid gas sensor was developed using a simple fabrication process from the combination of porous silicon (PSi ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Electrodeposition of strictly alpha,alpha’-polythiophene chains on oxidizable metals in acidic concentrated aqueous media

Journal of Electrochemical Science and Engineering, 2022
Electropolymerization of thiophene was performed in aqueous acidic media on various substrates, namely, titanium, nickel and SS steel. The films were successfully elaborated using voltamperometric, chronopotentiometric and chronoamperometric techniques ...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Poly(Alkoxythiophene) Rod‐Coil Block Copolymers for Organic Electrochemical Transistors

Advanced Materials, EarlyView.
We present the first synthesis of poly(3‐alkoxythiophene) rod‐coil block copolymers as a new architecture for OMIECs. Incorporating PEG and PLLA coils can enhance device performance beyond the homopolymer. The figure‐of‐merit depends uniquely on coil length.

Insulator-to-metal transition in polythiophene [PDF]

Physical Review B, 1994
In the present work, the electronic structure of polythiophene at several doping levels is investigated by the use of the H\"uckel Hamiltonian with \ensuremath{\sigma}-bond compressibility. Excess charges are assumed to be stored in conformational defects of the bipolaron type.
