“…The light intensities for these systems were low; however, light was indeed observed. Also, rubrene and DPA were shown to give ECL using TPrA as a co-reactant when immobilized onto Langmuir–Blodgett films in water at the electrode surface, giving higher intensities than the NP and NR examples . These examples demonstrate that the ECL mechanism via TPrA oxidation may be easier in the presence of water.…”

As stated above, oxalate was able to produce an excited state with rubrene and DPA, which was surprising since oxalate will likely not enter the oil phase.…”

We describe a method to produce electrogenerated chemiluminescence (ECL) in water using a family of highly hydrophobic polycyclic aromatic hydrocarbon (PAH) luminophores and boron dipyrromethene (BODIPY). This method is based on an oil-in-water emulsion system. Various PAHs (rubrene, 9,10-diphenylanthracene, pyrene, or perylene) and BODIPY were trapped in a toluene and tri-n-propylamine mixed oil-in-water emulsion using an ionic liquid as the supporting electrolyte and emulsifier. ECL was observed for all the aforementioned PAHs and BODIPY, and the rubrene and BODIPY emulsion systems showed adequate light to record an ECL spectrum. ECL was also observed using oxalate as the co-reactant, which was dissolved in the aqueous continuous phase. The emulsions were stable for hours and showed a droplet size distribution that ranged from 275 to 764 nm, in accordance with dynamic light scattering data.

“…For instance, Zholudov et al. incorporated DPA or rubrene in a polymer network on an ITO electrode and successfully measured their oxidation by CV [99] . However, the balance between the electronic and ionic conductivities of the layer as well as its structural stability must be considered when determining the composite's optimal composition.…”

Precise control over redox properties is essential for high‐performance organic electronic devices such as organic batteries, electrochromic devices, and information storage devices. In this context, multi‐redox active carbons and hydrocarbons, represented as CxHy molecules (x≥1, y≥0), are highly sought after, because they can switch between multiple redox states. Herein, we outline the redox properties of CxHy molecules as solutes and adsorbed species. Furthermore, the limitations of evaluating their redox properties and the possible solutions are summarized. Additionally, the theoretical capacity (mAh/g) and gravimetric energy density (Wh/kg) of secondary batteries were estimated based on the redox properties of 185 CxHy molecules, which have primarily been reported in the last decade. Among them, seven CxHy molecules were found to have the potential to surpass the energy density of LiNi0.6Mn0.2Co0.2O2/graphite batteries. The use of CxHy molecules in multielectrochromic devices and multi‐bit memory is also explained. We believe that this review will encourage further utilization of CxHy molecules thereby promoting its applications in organic electronic devices.

“…They are deemed to be an important active ingredient for future generation superfast molecular devices, nano-materials and nano-devices (6,7). Several PAHs have been used to fabricate LB film based light emitting diodes (LEDs), optical switches and sensors (8,9). Interest in an important PAH, namely coronene, also known as superbenzene stems from the fact that it has an intense structured fluorescence in the green region of visible spectrum that makes it a good candidate for excellent fluorescent molecular probe as revealed in several studies (10,11).Due to its high molecular symmetry (D 6h ), coronene has been favorite for spectroscopic studies.…”

Excellent Langmuir-Blodgett films (LB) of non-amphiphilic coronene (COR) have been prepared by mixing with a long chain fatty acid, viz., arachidic acid (AA) and an inert polymer such as poly methyl methacrylate (PMMA) separately. Miscibility of the guest and host molecules in the mixed monolayer of COR and AA/PMMA have been studied with excess area criterion. Both the attractive and repulsive interactions are present in the COR/AA mixed monolayer, whereas only repulsive interaction is active between the component molecules of COR/PMMA mixed monolayer. Spectroscopic properties of COR in solution and mixed LB films have been compared by UV-Vis absorption spectroscopy. Surface morphology of mixed LB films has been examined by atomic force microscopy (AFM). Absorption spectroscopic study complemented with AFM image suggests the formation of some kind of aggregates in the mixed LB films.
