A major global issue that the world is facing today is the upcoming
depletion of fossil fuels and the energy crisis. In 1998, the
global annual energy consumption was 12. 7 TW; of which 80% was
generated from fossil fuels. This also translates into huge annual
emissions of CO that leads to massive environmental problems, 2
particularly the global warming, which could be disastrous. Future
global annual energy needs are also estimated to rise dramatically.
A major challenge confronting the world is to ?nd an additional
14-20 TW by 2050 when our energy reserves based on fossil fuels are
vanishing. The massive demand for energy would require materials
and/or processes that would help to provide new sources of clean
ren- able energy or to develop processes that would harvest energy
or to better utilize energy in an ef?cient manner. The present
monograph, WOLEDs and Organic Photovoltaics - Recent Advances and
Applications, focuses on a very important and timely subject of
topical interest that deals with the more ef?cient use of energy
through white organic light-emitting diodes (WOLEDs) for
solid-state lighting and the development of clean sources of
renewable energy through the harvesting of light energy for
conversion into electrical energy in organic photovoltaics. While
LED solid-state lighting and photovoltaics have been dominated by
inorganic semiconductor materials and silicon-based solar cells,
there have been growing interests in the development of WOLEDs and
organic photovoltaics.
Functional materials research is one of the high priority strategic
areas of - st velopmentinscienceandtechnologyinthe21
century.Amongstthevarietyof
functions,theinteractionofmatterwithlighttogeneratelight-drivenorpho-
responsive properties has always been one of the most appealing and
attr- tive areas. Recent advances in the exploitation of transition
metal complexes in bringing about photo-induced functions have
attracted growing attention, particularly in areas related to
materials, energy, and biomedical research. Selected examples
include the development of molecular triplet emitters for organic
light-emitting devices (OLEDs), optical and photo-switches, pho-
chemical energy storage, dye-sensitized solar cells, photochemical
molecular
devices(PMD)andmachines,opticalandluminescenceprobesandchemos-
sors,luminescentlabelsandtagsforbiomolecules,andluminescencesignaling
and imaging. This volume serves to provide the readers with some
fundamentals of - minescent transition metal complexes and the
recent exciting developments of a selected variety of functions and
potential applications that transition metal complexes can offer
for the betterment of the society in areas related to materials,
energy, and biomedical research. The ?rst chapter of this volume by
Balch discussed the current progress in two-coordinate luminescent
gold(I) complexes. This class of complexes is well-known to show
weak metal***metal interactions that lead to the iso- tionofnovel
architecturesand polymorphism fromrelatively simple building
blocksandtheappearanceofuniqueelectronicabsorptionandemissionsp-
troscopicfeatures.Theeffectoftheenvironment,suchassolventsandcounter
ions, on the luminescence behavior of a number of two-coordinate
gold(I) complexes was discussed.
