“…Regarding polyazomethines without LC properties in the context of photovoltaic applications, some researchers proposed to use them as a donor in the active layer [67][68][69][70][71][72][73][74]. The first paper about PAZ for solar cells was published by Sharma et al [67].…”

“…Bolduc et al [73] received a PCE value for polyazomethines with two thiophene rings per unit equal to 0.07 and 0.22%, depending on the length of the aliphatic side chain. In our previous work [74], we proposed an applied 10-camphorsulfonic acid (CSA) as a dopant to not only improve the solubility of polyazomethine but also enhance the photovoltaic parameters of the constructed polymer solar cells and improve the morphology of the active layer. The PCE value of the device based on PAZ:PCBM:CSA was 40 times higher than that of the device based on PAZ:PCBM (1:3).…”

Five new azomethine polymers having aliphatic-aromatic moieties were synthesized by polycondensation reaction of dialdehydes and diamines. The dialdehyde monomers differ only in the orientation of the aromatic ring (ortho or para) and were synthesized by condensation reaction between aromatic aldehyde and 1,6-dibromohexane. The molecular mass of the monomers was recorded through E.I mass spectrum. The polymers structures were confirmed by elemental microanalysis, FT-IR, 1 HNMR and UV-Vis Spectroscopy. The morphology of monomers and polymers was evaluated by scanning electron microscopy (SEM). All the polymers were soluble in DMSO (on heating) and somewhat in other solvents. Thermal stability of polymers was analyzed by thermogravimetry (TG) and differential thermal analysis (DTA), all the polymers showed good thermal stability higher than their corresponding monomers. The TG of polymers indicated maximum rate of weight loss (T max) within 412-708 °C. Fluorescence emission spectra of polymers were recorded and the results indicated that all the polymers were photo-responsive and indicated 1 to 4 emission bands with maximum within 349-606 nm. The limit of detection of polymers was within 0.625-1.25 µg/ml. The polymers were also examined for their antimicrobial activities against bacteria and fungi.

In 1996 Sir Harold W. Kroto, Robert F. Curl and Richard E. Smalley were honored with the Nobel Prize in Chemistry for the discovery of fullerenes. The advent of these new forms of carbon heralded a race to understand the physical and chemical properties. C 60 is virtually insoluble in polar solvents but is partially soluble in benzene, toluene, and carbon disulfide. This made the processing of fullerenes for new applications fairly problematic. However, the physical and chemical properties of these cage structures may be tailored for a wide range of applications. Some of the difficulties in processing have been overcome by using novel fullerene derivatives. The functionalization of the fullerene core with different chemical moieties provided a vector toward potential applications in drug delivery, optoelectronics, electrochemistry and organic photovoltaics. In this review, we will take a closer look at the features of some of the fullerene derivatives that have reinvigorated the field of fullerene research. Water-soluble polyhydroxylated fullerenes such as fullerenol have demonstrated the potential for good electron transfer and optical transmission, while hydrophobic fullerene derivatives have shown promising avenues for catalytic applications. 2015 marked the 30 th anniversary of the discovery of fullerenes, with celebrations around the world including an event by the Royal Society of Chemistry, bringing together many of Sir Harold Kroto's former students. The event also coincided with the recent discovery of C 60 + in space after a complex twenty-year search. It is with sadness that we, Harry's Research Group at Florida State University, and his international collaborators, reflect on the passing of Sir Harold Kroto. His dedication to science and commitment to science communication through the VEGA Science Trust and the Global Educational Outreach for Science Engineering and Technology (GEOSET) initiative help to raise awareness of the challenges for science in the modern world. We will continue to inspire young students through outreach activities he initiated. Nanostructured carbon materials including fullerenes, carbon nanotubes, graphene and carbon black have the potential to be transformative in many areas from medicine to engineering. Research into carbon nanotubes is diverse in areas such as electrochemical devices, field emission, sensors and probes. [1][2][3][4] Recently, carbon nanotubes have been used as additives in the thermoplastics typically used for 3D printing. 5,6 Graphene is the latest material to have peaked interest in the carbon field in a similar manner to carbon nanotubes, with a range of potential applications.7 Graphene oxide is being explored in the production of 3D holographic images. 8The famous paper in Nature, C60:Buckminsterfullerene, 9 introduced the world to the new form of carbon but the road to general acceptance at that time was difficult, even with mounting evidence in support of the discovery. The paper, now cited over 10,000 times has become the central point of referen...
