ABSTRACT

This chapter summarizes recent research from our laboratory

on multichromophoric molecules that perform as components of

artificial photosynthetic systems. The basic scientific principles

underlying the design of these molecules were drawn from natural

photosynthetic energy conversion, but thematerials used to prepare

them are synthetic. The systems consist of chromophores and elec-

tron and energy donors and acceptors that have been chemically

linked to form artificial reaction centers and antennas, and to mimic

some aspects of photosynthetic regulation and photoprotection.

These chromophores include porphyrins, fullerenes, carotenoid

polyenes, antenna moieties, and photochromic materials. We begin

with an introduction to artificial photosynthesis and a simple exam-

ple. More complex systems including multichromophore arrays

and systems that incorporate photoregulatory elements are then

discussed. We have chosen examples based on a single organic

framework-hexaphenylbenzene-as an organizing unit for the var-

ious chromophores, donors, and acceptors.
