“…Carbon nano-peapods, that are highly attractive for solid state electronics [156] or MRI contrast agents, [91] are prepared by encapsulation of fullerenes (C 60 , C 70 or higher order fullerenes) inside CNTs or CNHs. Such conjugation exhibits bandgap tuning [157] and electron density differences.…”

Environmental context. Recent developments in nanotechnology have focussed towards innovation and usage of multifunctional and superior hybrid nanomaterials. Possible exposure of these novel nanohybrids can lead to unpredicted environmental fate, transport, transformation and toxicity scenarios. Environmentally relevant emerging properties and potential environmental implications of these newer materials need to be systematically studied to prevent harmful effects towards the aquatic environment and ecology.Abstract. Nanomaterial synthesis and modification for applications have progressed to a great extent in the last decades. Manipulation of the physicochemical properties of a material at the nanoscale has been extensively performed to produce materials for novel applications. Controlling the size, shape, surface functionality, etc. has been key to successful implementation of nanomaterials in multidimensional usage for electronics, optics, biomedicine, drug delivery and green fuel technology. Recently, a focus has been on the conjugation of two or more nanomaterials to achieve increased multifunctionality as well as creating opportunities for next generation materials with enhanced performance. With incremental production and potential usage of such nanohybrids come the concerns about their ecological and environmental effects, which will be dictated by their not-yet-understood physicochemical properties. While environmental implication studies concerning the single materials are yet to give an integrated mechanistic understanding and predictability of their environmental fate and transport, the importance of studying the novel nanohybrids with their multidimensional and complex behaviour in environmental and biological exposure systems are immense. This article critically reviews the literature of nanohybrids and identifies potential environmental uncertainties of these emerging 'horizon materials'.

“…The first molecules ever inserted into SWCNTs were C 60 fullerenes [46,64] thereby forming the so-called nanopeapods [ Figures 5a.2(a), and Chapter 5b]. Many fullerene-related filling materials have then followed, including higher fullerenes until C 90 [95], endohedral fullerenes such as N@C 60 [78], Sc 3 N@C 80 and Er x Sc 3-x N@C 80 [96], Dy 3 N@C 80 [97], Gd@C 82 [95,98], La@C 82 and La 2 @C 82 [99], Dy@C 82 [95,100], Sm@C 82 [101,102], Sc 2 @C 84 [102], and Gd 2 @C 92 [103,104], functionalized fullerenes such as [cyclopropa-C 60 -dicarboxylic acid diethyl ester (abbreviated as C 61 (COOEt) 2 @SWCNT [79]) and fullerenes grafted with a retinal chromophore [77]. Regarding the former category (i.e.…”

“…Regarding the former category (i.e. higher fullerenes), C 90 is the largest (empty) fullerene deliberately inserted in SWCNTs so far [95], while Gd@C 92 endofullerenes were the largest such species encapsulated in this category [103,104]. Elongated capsules obtained from the in situ coalescence of encapsulated C 60 upon various processes (see Chapter 5b) may also be considered higher fullerenes (for example, consider the formation of C 120 from the coalescence of two C 60 molecules).…”

“…Again, most of the work published thus far deals with peapods and related materials and has addressed issues related to thermal properties [165], transport and charge transfers (between the encapsulated materials and the containing SWCNT) [95,100,[165][166][167][168][169][170][171][172]. Those aspects will be presented in Chapter 5b.…”

Whilst fullerene and related materials are the most inserted molecules in carbon nanotubes (CNTs), other molecular species including Zn-diphenylporphyrin (i.e. Zn-DPP) [1], orthocarborane [2,3], metallocenes [4,5], octasiloxane [6] and squarylium dye [7], among others have been encapsulated within either single-, double-or multiple walled carbon nanotubes (SWCNTs, DWCNTs and MWCNTs, respectively) and directly imaged by either high resolution transmission electron microscopy (HRTEM) or related techniques. In tandem with these studies, one-dimensional (1D) nanowires of a wide variety of materials including multiplets of polymeric iodine chains [8,9]

This chapter reviews the recent progress on structures and properties of nanopeapods (single-wall carbon nanotubes (SWNTs) encapsulating fullerenes or metallofullerenes) by the high-resolution transmission electron microscope (HRTEM), electron energy-loss spectroscopy (EELS), low-temperature scanning tunneling microscope (STM) and spectroscopy (STS), and field effect transistor (FET) transport measurements together with the details of their synthesis methods. The potential abilities of this novel hybrid material for electronic devices, sample cells for TEM and reaction chambers at a molecular scale are discussed.
