Summary: | Carbon nanorings have attracted substantial interest from synthetic chemists due to their unique topological structures and distinct physical properties. An intriguing π-conjugated double-nanoring structure, denoted as [8]CPP-[10]cyclacene, was constructed
via
the integration of [8]cycloparaphenylene ([8]CPP) into [10]cyclacene. Using the external electric field stimuli-responsiveness of [8]CPP-[10]cyclacene, directional charge transfer can be induced, resulting in the emergence of intriguing properties. The effects of the external electric field in three specific directions were explored, vertically in the [8]CPP unit (
F
y
), vertically in the [10]cyclacene unit (
F
z
), and horizontally along the double nanorings diameter (
F
x
). Interestingly, the external electric field vertically to the [10]cyclacene unit significantly enhanced the first hyperpolarizability (
β
tot
) compared to that vertically to the [8]CPP unit. Notably, [8]CPP-[10]cyclacene under
F
x
exhibited significantly larger the
β
tot
values (1.48 × 10
5
a.u.) than those of vertical
F
y
and
F
z
. This work opens up a wide range of nonlinear optics, making it a compelling area to explore in the field of carbon nanomaterials.
