By combining time-correlated single photon counting (TCSPC) measurements, density functional theory (DFT), and time-dependent DFT (TD-DFT) calculations, we herein investigate the role of protons, in solutions and on semiconductor surfaces, for the em

Bilirubin (BR) is the main end-product of the hemoglobin catabolism. For decades, its photophysics has been mainly discussed in terms of ultrafast deactivation of the excited state in solution, where, indeed, BR shows a very low green emission quantu

The Solid-State Emission of Bilirubin

Autor: Taha Ahmed, Ahmed M. El-Zohry, Burkhard Zietz

Bilirubin (BR) is a human-biological compound formed during the haem metabolism that is insoluble in most solvents. BR has shown short emission lifetime with low quantum yield in limited number of solvents, due to the non-radiative ultrafast isomeriz

Interligand electron transfer (ILET) of the lowest metal-to-ligand charge transfer (MLCT) state of N712 (cis-[Ru(dcb)2(NCS)2]4−, where dcb = 4,4′-dicarboxylate-2,2′-bipyridine) in a deuterated acetonitrile solution has been studied by means of

Developing norbornadiene–quadricyclane (NBD–QC) systems for molecular solar-thermal (MOST) energy storage is often a process of trial and error. By studying a series of norbornadienes (NBD-R2) doubly substituted at the C7-position with R = H, Me,
