Colossal C Fullertubes: Soluble [5,5] C-D(1) Pristine Molecules with 70 Nanotube Carbons and Two 30-Atom Hemifullerene End-caps.

We report the seminal experimental isolation and DFT characterization of pristine [5,5] C-D(1) fullertubes. This achievement represents the largest soluble carbon molecule obtained in its pristine form. The [5,5] C species is the highest aspect ratio fullertube purified to date and now surpasses the recent gigantic [5,5] C-D(1).

Gigantic C Fullertubes: Prediction and Experimental Evidence for Isomerically Purified Metallic [5,5] C-D(1) and Nonmetallic [10,0] C-D(10766).

We report the first experimental characterization of isomerically pure and pristine C fullertubes, [5,5] C-D(1) and [10,0] C-D(10766). These new molecules represent the highest aspect ratio fullertubes isolated to date; for example, the prior largest empty cage fullertube was [5,5] C-D(1). This increase of 20 carbon atoms represents a gigantic leap in comparison to of C-C fullerene research.

Semiconducting and Metallic [5,5] Fullertube Nanowires: Characterization of Pristine D(1)-C and D(1)-C.

Although fullerenes were discovered nearly 35 years ago, scientists still struggle to isolate "single molecule" tubular fullerenes larger than C. In similar fashion, there is a paucity of reports for pristine single-walled carbon nanotubes (SWNTs). In spite of Herculean efforts, the isolation and properties of pristine members of these carbonaceous classes remain largely unfulfilled.
