The synthesis, structure and photoluminescence of coumarin-based chromophores

Coumarin-based chromophores with azo and pyrazoline moieties were synthesized and their structures and properties elucidated using spectroscopy. The coumarins were luminescent, having solid state emission at wavelengths ranging from 400 to 750 nm, depending on structure. The relationships between th...

Description
Summary:Coumarin-based chromophores with azo and pyrazoline moieties were synthesized and their structures and properties elucidated using spectroscopy. The coumarins were luminescent, having solid state emission at wavelengths ranging from 400 to 750 nm, depending on structure. The relationships between the solid state photoluminescence and both chemical and crystal structures are discussed.
