“…This process is considered to be straightforward in comparison to traditional synthetic routes. Other reports have indicated the use of norbonenemethyl amine with substituted alkanoic acids of various carbon chain length (degree of alkylation) [ Figure 4) in the synthesis of a novel Cobalt (iii) surfactant [14]. Some studies, on the other hand, employed ion-exchange techniques from metal hydroxides in the synthesis of double metal surfactant films [23].…”

“…The self-assembly property has also been considered to be a means of generating "supramolecular assemblies" which pave a way for the many applications of these materials [5]. Research has also indicated that the metal containing property of organometallic surfactants has given them more opportunities to form various structures and has opened a door for them in terms of performance related properties compared to their non-metal containing surfactant counterparts [14].…”

“…Regarding the characterisation of organometallic surfactants, many spectroscopic techniques have been found to be relevant. Some of the techniques commonly reported in the literature include: infra red (IR) spectroscopy [9] [14] [35] [37] [42] for functional group identification, nuclear magnetic resonance (NMR) for proton group/environment identification and UV-Visible spectroscopy [14].…”

“…To fully understand structure of many of the surfactants, a range of analytical techniques can be used on the basis of elemental analysis, spectroscopy, diffraction [15] and microscopy [38]. Other relevant techniques that can also be employed include cytotoxicity and biological activity studies [39], combustion analysis [14] [40], auto-oxidation studies [16], and pyrolysis [41].…”

“…Transitional metal containing materials are more commonly known and these are typically first or second raw transition metals (d-block elements of the periodic table) with other accounts involving the lanthanides. Most of the surfactants that fall under the transition metal category contain one or more of elements including Scandium (Sc) [7], Titanium (Ti) [8]- [10], Vanadium (V) [10] [11], Chromium (Cr) [9], Iron (Fe) [12] [13], Cobalt (Co) [14], Nickel (Ni) [15], Copper (Cu) [16], Zinc Zn [17], Yttrium (Y) [9], Zirconium (Zr) [8] [18] [19], Niobium (Nb) [20], Palladium (Pd) [15], Silver (Ag) [6], Lanthanum (La), Europium (Eu), Gadolinium (Gd), Ytterbium (Yb) [21], Hafnium (Hf) [8] and Osmium (Os) [22]. Similarly, there are a number of reports on non-transition metal-based organometallic surfactants.…”

New classes of liquid‐crystalline semiconductor polymers based on perylene diester benzimidazole and perylene diester imide mesogens are reported. Two highly soluble side‐chain polymers, poly(perylene diester benzimidazole acrylate) (PPDB) and poly(perylene diester imide acrylate) (PPDI) are synthesized by nitroxide‐mediated radical polymerization (NMRP). PPDB shows n‐type semiconductor performance with electron mobilities of 3.2 × 10−4 cm2 V−1 s−1 obtained in a diode configuration by fitting the space‐charge‐limited currents (SCLC) according to the Mott–Gurney equation. Interestingly, PPDI performs preferentially as a p‐type material with a hole mobility of 1.5 × 10−4 cm2 V−1 s−1, which is attributed to the less electron‐deficient perylene core of PPDI compared to PPDB. Optical properties are investigated by UV‐vis and fluorescence spectroscopy. The extended π‐conjugation system due to the benzimidazole unit of PPDB leads to a considerably broader absorption in the visible region compared to PPDI. HOMO and LUMO levels of the polymers are also determined by cyclic voltammetry; the resulting energy band‐gaps are 1.86 eV for PPDB and 2.16 eV for PPDI. Thermal behavior and liquid crystallinity are studied by differential scanning calorimetry, polarized optical microscopy, and X‐ray diffraction measurements. The results indicate liquid‐crystalline order of the polymers over a broad temperature range. These thermal, electrical, and optical properties make the perylene side‐chain polymers attractive materials for organic photovoltaics.
