Light emitting polymers excited states

In this chapter we present a description of the excited states of the phenyl-based light emitting polymers. This description is achieved by using the theoretical and computational modelling of these systems to interpret the experimental evidence acquired by a wide variety of spectroscopic probes. 

The experimental and theoretical studies of light emitting polymers described in this chapter suggest that the excited states can be understood as follows ... 

This chapter has described the spectroscopic and theoretical investigations of the excited states of light emitting polymers. Although the experiments are generally... 

A final aim of this book is to demonstrate how our theoretical rmderstand-ing of excited states enables us to make a consistent interpretation of experimental results. Two final chapters draw these themes together in discussing frans-polyacetylene, and the hugely technologically important phenyl-based light emitting polymers. 

The use of transition or rare earth metal complexes as emitting materials for OLED has attracted much attention recently because of the enhancement in EL efficiency from triplet excited state.16 Chan and co-workers demonstrated that incorporation of ruthenium bipyridyl complexes into conjugated polymers would enhance the charge carrier mobilities.17 Through attachment of different transition metal complexes onto polymer chains, tuning of light-emitting properties could be achieved.18...
