Carbon nanoonion-ferrocene conjugates as acceptors in organic photovoltaic devices

Abstract

This study is the first to use carbon nanoonion-based derivatives as acceptors in organic photovoltaic devices (PCE = 1.89%).

Do Carbon Nano‐onions Behave as Nanoscopic Faraday Cages? A Comparison of the Reactivity of C60, C240, C60@C240, Li+@C60, Li+@C240, and Li+@C60@C240

“…Mordkovich reported in 2000, the generation of the double‐shell C 60 @C 240 and C 240 @C 560 and triple‐shell C 60 @C 240 @C 560 CNOs in the products of the high‐temperature laser pyrolysis . CNOs have been recently proposed as acceptors in donor–acceptor dyads for organic photovoltaics . In fact, the photoinduced lowest charge‐transfer (CT) excitation in CNOs takes place at lower energy than any transition of the individual fullerenes that form the CNO .…”

Self‐Supported CoP Nanoparticle‐Embedded Wood‐Derived Porous Carbon Membrane for Efficient H2 Evolution in Both Acidic and Basic Solutions

“…The relative intensity ratios of D‐band to G‐band ( I D / I G ) for the Co@PCM (1.093) and CoP@PCM (1.094) are larger than that of PCM (0.981), suggesting that the graphitization of carbon microdomains around Co or CoP species decreases due to the strong interaction between Co or CoP species and PCM . However, in comparison with the PCM, a strong 2D‐band at 2688 cm −1 that is Raman active for crystalline and sensitive to the π band in the graphitic electronic structure could be observed for both Co@PCM and CoP@PCM, which indicates that the formation of graphene‐like carbon layers around Co and CoP nanoparticles, consistent with the TEM result. This will endows the CoP@PCM with high conductivity to facilitate the electron transfer for efficient HER electrocatalysis.…”

Polymeric Network Hierarchically Organized on Carbon Nano-onions: Block Polymerization as a Tool for the Controlled Formation of Specific Pore Diameters

“…After functionalization of the pristine CNOs, the number of aromatic bonds decreases, which results in a decrease in the I D / I G ratio from 2.42 to 1.83. 45 Both the polymer and CNO–polymer hybrids after pyrolysis, C-4 and C-6 ( Figure S22A , spectra c and d), possess wide overlapping bands at 1310 and 1337 cm –1 , respectively, which may be assigned to C atoms with sp 3 hybridization, and bands at 1583 and 1590 cm –1 , respectively, attributed to vibrations of the sp 2 -hybridized carbon atoms. These vibrations are characteristic of carbonaceous materials and are attributed to the transformation of organic polymers to the carbon skeleton.…”
