“…For small conjugated oligomers, the charge carrier -phonon assembly (so-called polaron) can delocalize over the whole molecule and, hence, λ i strongly depends on the size of the oligomer. As described before, a single exponential equation analogous to equation (10) was employed to fit the λ i values as a function of n and to obtain an estimate at the polymer limit (see Figure 5). These estimated λ i values for the infinite polymer chains are within the 0.020 -0.037 eV and 0.024 -0.054 eV ranges for electron and hole transport, respectively.…”

[9][10][11][12][13][14] The interesting electronic properties exhibited by PAEs can be related to the axial symmetry of ethynylene groups, which allows to maintain the conjugation (note that between adjacent aryl groups at different relative orientations rotational barriers are as small as 1 kcal mol -1 in these cases) [15][16][17][18][19][20] across the whole molecular backbone.…”

A set of engineered crystalline polymers containing thiazolo [5,4-d]thiazole and arene imides linked by ethynylene bridges have been modelled by means of Density Functional Theory (periodic boundary) calculations. A large set of relevant electronic properties related to the opto-electronic and semiconductor character of these systems, such as optical band gap, frontier molecular orbital energy levels, electron affinity, ionization potential, reorganization energy, and electronic coupling between neighboring polymer chains were obtained. We further discuss the effect of the ethynylene linkages, the presence of heteroatoms in thiazolo [5,4-d]thiazole rings, and

Stereoregular polymers like isotactic poly(N‐butenyl‐carbazole) (i‐PBK), isotactic and syndiotactic poly(N‐pentenyl‐carbazole) (i‐PPK and s‐PPK), and poly(N‐hexenyl‐carbazole) (i‐PHK and s‐PHK) are synthesized using the stereospecific homogeneous “single site” Ziegler‐Natta (Z‐N) catalysts: rac‐dimethylsilylbis(1‐indenyl)zirconium dichloride (1)/methylaluminoxane (MAO) and diphenylmethylidene(cyclopentadienyl)‐(9‐fluorenyl)zirconium dichloride (2)/MAO. Catalytic activity is rationalized by density functional theory (DFT) calculations. All synthesized polymers are fully characterized by NMR, thermal, wide‐angle X‐ray diffraction, and fourier transform infrared spectroscopy analysis. Fluorescence measurements on isotactic and syndiotactic polymer films indicate that all polymers give rise to excimers, both “sandwich‐like” and “partially overlapping.” Excimer formation is essentially driven by the polymer tacticity. Isotactic polymers generate both sandwich‐like and partially overlapping excimers, while syndiotactic polymers give rise especially to partially overlapping ones. A theoretical combined molecular dynamics–time dependent DFT approach is also used to support the experimental results. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

“…Polycarbazole [ 31 ] is a linear conjugated polymer with an aromatic heterocyclic ring containing nitrogen atoms. Its conjugated structure is extended by a benzene ring, which is similar to a molecular wire, giving electrical conductivity [ 32 ]. The carbazole ring located in the main part of the polymer is conducive to carrier migration.…”

In this study, four polycarbazole derivatives (PCMB-Ds) with different alkyl side chains were designed and synthesized via Wittig–Horner reaction. A novel solid-phase electrochemiluminescence (ECL) system was prepared by immobilizing PCMB-D on an indium tin oxide (ITO) electrode with polyvinylidene fluoride (PVDF) in the presence of tripropylamine (TPrA). It could be found that the increase in alkyl side chain length had little effect on the ECL signal of PCMB-D, while the increase in the degree of polymerization (DP) greatly enhanced the ECL signal. Furthermore, the P-3/ITO ECL sensor based on the polyoctylcarbazole derivative (P-3) with the best ECL performance was successfully constructed and detected Fe3+ under the optimal experimental conditions. The ECL signal steadily diminished with the increased concentration of Fe3+ because of the competition and complexation between Fe3+ and P-3 under the condition of pH 7.4. This P-3/ITO platform could realize a highly sensitive and selective detection of Fe3+ with a wide detection range (from 6 × 10−8 mol/L to 1 × 10−5 mol/L) and low detection limit of 2 × 10−8 mol/L, which could allow the detection of Fe3+ in multiple scenarios, and would have a great application prospect.
