Abstract
We
report
a
light‐responsive
tetrahedral
metal–organic
capsule
that
binds
perrhenate
catalyst,
which
is
released
selectively
upon
irradiation
with
350
nm
light,
turning
on
the
catalytic
reduction
of
organic
carbonyls
by
hydrosilanes.
The
activity
can
be
switched
off
heating
at
75
°C
for
2.5
h,
stimulates
reformation
and
catalyst
re‐encapsulation.
Multiple
on‐off
cycles
were
shown,
clear
relationship
between
product
yield
light
time.
Encapsulation
thus
enables
coupling
light‐responsiveness
to
catalysis
in
manner
might
generalized
other
catalysts
capsules.
