The cycloaddition of azomethine ylides has been used to
covalently link the thienylazobenzeneamine 2 to
[60]fullerene. When the resulting donor-acceptor dyad 1,
with an enhanced absorption in the Vis region, was used
as the active layer of a photovoltaic cell, a power
conversion efficiency of 0.16% was obtained, under 80
mW cm-2 white light illumination
