Abstract

A semiconducting organic nanotube composed of a graphite-like bilayer of columnarly assembled hexabenzocoronene units (see figure) changes its photoconductivity in response to photoisomerization of the photochromic dithienylethene pendants on the surface. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset.

25. On continuous excitation of the HBC units in1NT/closed the absorption band of DTE gradually decreased in intensity (Fig. S6) due to its isomerization into the open form. This isomerization is considered to be the consequence of an energy transfer from photoexcited HBC to DTE. In contrast no isomerization was observed for1NT/open.
26. Wide‐angle X‐ray diffraction patterns of1NT/openand1NT/closedare not different from one another and virtually the same as those observed for the nanotube formed from an amphiphilic hexabenzocoronene without DTE [6d].
