Assunto(s): coumarin; 4-styrylcoumarin derivatives; fluorescent labels; biomolecules labeling; large Stokes shifts
A series of novel 2-piperidinium-4-styrylcoumarin derivatives, with large Stokes shifts and high fluorescence quantum yields, were synthesized using an efficient and low-cost synthetic strategy as potential fluorescent labels for biomolecules. Density functional theory and time-dependent density functional theory calculations were performed in order to rationalize the observed photophysical properties.
The study was performed under the framework of THE SCREAM Project-“Touchstone for Heritage Endangered by Salt Crystallization, a Research Enterprise on the Art of Munch” (ref. FCTALT20- 03-0145-FEDER-031577) nanced by the Portuguese Foundation for Science and Technology (FCT) through National and European Funds, PROBIOMA project (0483_PROBIOMA_ 5_E, EP), co-nanced by the FEDER, through the programme INTERREG VA Espa˜na—Portugal (POCTEP) and the City University of Macau endowment to the Sustainable Heritage Chair.
