Polythiophene and its derivatives are valuable conjugated polymers due to their physical properties and applications in various fields. Precursors of polythiophenes were conventionally obtained from petrochemical byproducts, which are non-renewable. Thiophene and its derivatives had been found naturally in Tagetes species such as Tagetes erecta, Tagetes tenuifolia, etc. Tagetes species produce 2, 2':5', 2''-terthienyl (Alpha-T), 5-(3-buten-1-ynyl)-2, 20-bithienyl (BBT), 5-(4-hydroxy-1-butynyl)-2, 20-bithienyl (BBTOH), and 5-(4-acetoxy-1-butynyl)-2, 20-bithienyl (BBTOAc), which are accumulated in different parts, specifically in the roots of the plants. These thiophene derivatives were extracted and identified by GC-MS, Uv-vis, FTIR and TLC analysis. The partially purified plant extract is polymerized through one step oxidative free radical polymerization to obtain polythiophenes. Product characterization has revealed that the selective polymerization of thiophene derivatives results in the phase-separated end product from the rest of the materials in the plant-extract.

“…Several types of conjugated oligomers and polymers were synthesized as new organic semiconductor candidates. [1][2][3][4][5][6][7][8][9][10][11] Among of the synthesized compounds for OTFTs candidates, many investigators have interest in anthracene moiety because of the characteristic results such as hole mobility. The hole mobility in anthracene single crystals was measured by the time-offlight photocurrent technique and found to reach up to 3 cm 2 V −1 s −1 at 300 K. 2 Since anthracene have shown good character for OTFTs, many research groups want to develop and find out more better structure of anthracene derivatives which have conjugated systems as OTFTs.…”

Here we report our recent result of a new semiconductor material, which has an asymmetric structure. The synthesized molecules consist of anthracene and thiophene connected by bridged ethylene and substituted with hexyl or dodecyl groups as pendants. The semiconductors were synthesized using a McMurry coupling reaction between anthracene-2-carbaldehyde and corresponding 5-hexyl(or dodecyl)thiophene-2-carbaldehyde. A first investigation of synthesized asymmetry AVHT (9a) and AVDT (9b) for the physical properties showed that they have high oxidation potential and thermal stability. The devices prepared by using AVHT (9a) and AVDT (9b) showed the mobility of 2.6 × 10 −2 cm 2 /Vs and 4.4 × 10 −3 cm 2 /Vs, respectively, in solution processed OTFTs.

“…A large fraction of recent work in this area is devoted to ab initio or density functional theory studies of the electron structure and emission/absorption properties of various polymers. 2 Molecular dynamics methods have been used to investigate the PAT conformation in different solvation regimes, [15][16][17] the structure and pressure/temperature responses of doped and undoped solidstate PAT films, 18,19 ion migration during PAT film doping, 20 and the orientation and dipole of an amphiphilic PT monolayer at an air/water interface. 21,22 In this article, we combine the above lines of investigation to model the insertion of single chains of EHPT and HPT into a patch of membrane.…”

Computational Modeling of Poly(alkylthiophene) Conductive Polymer Insertion into Phospholipid Bilayers

2007

We have previously demonstrated that some poly(alkylthiophenes) (PATs) are able to increase the electrical conductance of unsupported phospholipid bilayers and have hypothesized that this effect is due to the ability of some PAT side chains to permit stable insertion into the bilayer. We have further proposed the development of long-term intracellular electrodes based on that phenomenon. In this article, we apply molecular dynamics techniques to study the insertion of two model PATs into a patch of a lipid bilayer. Steered molecular dynamics is used to obtain potential trajectories of insertion, followed by umbrella sampling to determine the free-energy change upon insertion. Our results indicate that both branched-side-chain poly(3-(2-ethylhexyl)thiophene) (EHPT) and straightside-chain poly(3-hexylthiophene) (HPT) are able to enter the bilayer but only EHPT can cross the center of the membrane and establish an electrical bridge. HPT penetrates the head groups but is not able to enter the alkyl tail phase. These findings support the feasibility of our electrode concept and raise questions regarding the mechanisms by which branched side chains grant PATs greater solubility in a lipid bilayer environment. The parameters and methods used in this study establish a novel framework for studying these and similar systems, and the results hold promise for the use of EHPT in biosensing and neural interfacing.
