Low dimensional nanocarbons – chemistry and energy/electron transfer reactions

Abstract

This Minireview sheds light onto the electronic communication between, on one hand, low dimensional nanocarbonssingle and multiwalled 1D carbon nanotubes and 2D grapheneand, on the other hand, a variety of electroactive species en-route to novel electron donor-acceptor conjugates and hybrids in relation to their covalent and non-covalent chemistry, respectively. A common denominator to any of the highlighted conjugates/hybrids is charge transport across different scales, that is, from individual molecular conjugates/hybrids to morphologically controlled devices.

Creating and testing carbon interfaces – integrating oligomeric phthalocyanines onto single walled carbon nanotubes

“…FT-IR showed a characteristic peak at 2231 cm À1 , which is assigned to the cyano moieties. 1 H-NMR in THF-d 8 showed broad signals for the aromatic and also for the CH 3 O and -CH 2 O protons.…”

“…An interesting aspect for electronic applications is the manipulation of the electronic properties of semiconducting SWCNTs, which is at the forefront of current investigations. 8 Charge transfer/doping is a leading example of a potential strategy toward this aim, which is expected to substantially increase the density of free charge carriers and thereby enhance the electrical and thermal conductivities. Notable are contributions in the area of eld effect transistors.…”

Functionalized Nanocarbons for Artificial Photosynthesis: From Fullerene to SWCNT, Carbon Nanohorn, and Graphene

“…Similar situation would be anticipated for sensitizer-functionalized CNHs, which are one of the new nanocarbons. In the case of a few-layer graphene, which is mostly transparent in the visible light region, some modifi cations with photoactive molecules are necessary to convert them into the light-harvesting systems [ 9 ].…”

Recent advances in the catalytic asymmetric 1,3-dipolar cycloaddition of azomethine ylides

“…38 Therefore, the preparation of chiral enantioenriched fullerenes is a major goal since the stereochemical configuration exerts a great influence on some fullerene physical properties. 39 However, until recently, the lack of efficient synthetic methods for the enantioselective preparation of chiral fullerenes has hampered their applicability.…”
