Covalent
organic
frameworks
(COFs)
have
been
extensively
investigated
due
to
their
unique
structure,
porosity,
and
functionality.
However,
at
the
topological
level,
COFs
remain
as
two-dimensional
(2D)
or
three-dimensional
(3D)
structures,
while
with
one-dimensional
(1D)
topology
not

explored.
In
this
work,
we
proposed
a
