Abstract
The synthesis and optical properties of a novel family of 5-substituted-1,10-phenanthroline derivatives are reported herein. One carbon–carbon triple-bond function was introduced using a Sonogashira cross-coupling reaction. The effects on optical properties, of the substitution with electro-withdrawing or -donating substituents in the 5th position of the 1,10-phenanthroline are investigated. Experimental chemical structure–polarisability relationship is analyzed according to the Lippert–Mataga correlation and compared to a theoretical study carried out with DFT calculations. These compounds are promising candidates for a fine-tuning of the internal charge-transfers but also as potential nonlinear chromophores and ligands within multifunctional coordination complexes.
