III. Design Strategies and Building BlocksIn the second part of this contribution, we will demonstrate
how the basic principles discussed above can be utilized as a
starting point for creating artificial biomimetic and bioinspired
catalytic and photosynthetic devices. At present, only very few
examples of synthetic molecular systems, which are able to
replace all important functional aspects of their native
counterparts under mild and ambient conditions, have been
described in the literature( 6 ), including some important results
of our own work. In the last sections of this review, several
selected case studies from the author's research efforts in this
direction will therefore be presented.
Here, we will also try to promote our own personal view on the
possible roadmap to be followed for a rational development of
such light-controlled photocatalytic systems (3,5,8). The first
