“…We have shown earlier that the GO/PDA hybrid integrated with electron-transport layer (ETL) C 60 showed a photovoltaic behavior due to the PDA/C 60 donor-acceptor heterojunction [43]. In this work, we found that the GO/PDA system exhibits similar behavior in combination with the HTL 2-TNATA layers.…”

The presence of the red form of the PDA polymer suggests partial disordering of the polymer chains [43], most likely, due to the rearrangement of the head groups of the preorganized PCDA surfactant in a course of its deposition and/or polymerization on the solid-supported GO monolayers.…”

A combinatorial interfacial assembly method was developed for fabrication functionally different 2D hybrids by using the same starting set of components comprising graphene oxide, perylene chromophore, polydiacetylene surfactant and nickel nitrate as a source of divalent ions. The components were assembled through either hydrogen or coordination bonding into layered nanofilms with a thickness 8-20 nm to integrate them into conventional ITO-based solar cells. Depending on their composition, the hybrids provide different operational characteristics to the resulting devices. The combination of graphene oxide with the light-absorbing polymer provides photovoltaic properties, whereas the adding of nickel transforms the hybrid into the monopolar conductive layers. The combination of two chromophores gives a multipurpose nanoelement, which performs as either non-linear resistor, diode or photodiode. This strategy can be easily extended to other combinations of chemical tools for the design of various hybrid nanofilms with desirable functional properties for organic electronics.

“…This kind of assembly of binary compositions, when exploits specific interactions between GO and organic molecules, may lead to a synergy of properties useful for organic electronics. For example, a nondoped self-assembled GO/polydiacetylene hybrid layer showed an increase of lateral electric conductivity by 6 orders of magnitude compared to that of the individual components . However, the one-step integration of several organic species in a controlled manner to orchestrate their functioning in a single hybrid GO-based nanostructure remains a challenging issue.…”

One-Step Interfacial Integration of Graphene Oxide and Organic Chromophores into Multicomponent Nanohybrids with Photoelectric Properties

A one-step protocol for interfacial self-assembly of graphene oxide (GO), glutamine-substituted perylene diimide (PDI-glu), 10,12-pentacosadiynoic acid (PCDA), and zinc acetate into three-and four-component hybrid nanofilms through hydrogen and coordination bonding was developed. The hybrids deposited onto solid supports were studied after polymerization of PCDA by UV−vis absorption, fluorescence, and Raman spectroscopies, scanning electron microscopy (SEM), and atomic force microscopy (AFM). The results of spectroscopic studies suggest that the hybrids assembled through H-bonds can maintain the light-induced Forster energy transfer from the PDI-glu chromophore to the conjugated polymer and then to GO leading to fluorescence quenching. In the hybrids assembled through coordination bonding with zinc clusters, the energy transfer proceeds from PDI-glu to the PDA polymer, whereas the transfer from PDA to GO is quenched completely. Another important characteristic of these ultrathin hybrids is their stability with respect to photobleaching of chromophores due to the acceptor properties of GO. The as-assembled hybrid nanofilms were integrated with conventional photovoltaic planar architectures to study their photoelectric properties. The zinc-containing hybrids integrated with a hole transport layer exhibited photovoltaic properties. The cell with the integrated four-component hybrid comprising both PDI-glu and PDA showed a photocurrent/dark current ratio almost an order higher than that of the three-component hybrid assembled with PDA only. The supramolecular method based on the interfacial selfassembly can be extended to a wide variety of organic chromophores and polymerizable surfactants for integrating them into multicomponent functional GO-based nanohybrids with targeted properties for organic electronics.

This study aims to produce smart nanocomposite fibers using the electrospinning method for potential sensing applications. For this purpose, polyvinylpyrrolidone (PVP) and polydiacetylene (PDA) solutions at two different ratios are prepared and electrospun at the voltage of 15 kV, distance to the collector of 15 cm, and the flow rate of 1 mL/h. To enhance the mechanical properties and sensitivity of the fibers, graphene oxide (GO) is then added to the polymer solution at different percentages of 0.5 to 2 wt%, and electrospinning is performed under the optimized conditions. Based on SEM analysis, with increasing the percentage of GO, the average fiber diameter decreases from 180 nm (without graphene) to 150 nm (1.5 wt% GO) due to the higher conductivity of the polymer solution after incorporation of GO. FTIR spectra reveal the possible hydrogen bonding between the components. In order to investigate the colorimetric behavior of the electrospun nanofibers, they are subjected to various temperatures and pHs, and a color change from bluish‐purple to reddish‐pink is observed due to conformational changes in PDA macromolecules. Finally, DSC results confirm the higher thermal stability of the nanocomposite fibers containing GO. Therefore, the fabricated thermochromic nanofibers are potentially appropriate candidates as sensors.
