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.
The front cover illustrates a novel photoconductive nanotube by self‐assembly of a dithienylethene‐appended hexa‐peri‐hexabenzocoronene, where the graphite‐like nanotubular wall is laminated on both sides by densely packed dithienylethene pendants. The closed form of the photochromic pendant (green) serves as a better electron acceptor than its open form (yellow), so the photoconductivity of the nanotube...
