Abstract: | Cost effective and green protocols for the synthesis of two new series of coumarin based blue light emitting fluorophores named as ‘Beta Fluors’ and ‘Alpha Fluors’ are described. The coumarin alkylamide based Beta Fluors are developed using a one-step multi-component process in the presence of phenyl boronic acid as an efficient green catalyst. The Alpha Fluors are structured with coumarin–triazole–carboxamide peptidomimetics and their synthesis involves the ‘click with MCR’ concept. The new fluorophores gave high Stoke’s shift values for the emission wavelengths and their structural features are promising for further fine tuning to obtain preferred emission maxima. |
