Novel Multi-component Syntheses of Chromophores

Most impressive from the photophysical evaluation of the combinatorial libraries, a remarkable luminescent color versatility, spanning from blue to orange-red emission, can be observed. Furthermore, this set of data was well suited for correlations with static DFT calculations to establish whether it is feasible to predict the luminescent behavior of novel materials. 

The covalent assembly of functional Jt-systems is a general synthetic principle and in some cases they can even be achieved in a multi-component fashion. One of the most impressive examples is the very elegant access to covalently linked donor-fullerene arrangements by 1,3-dipolar cycloadditions with in situ-generated azomethine ylids [59]. However, here only the multi-component de novo synthesis of the chromophore structures will be considered. The major developments have been achieved in condensation-based and cross-coupling strategies.
