Ovalene Photophysics Revisited [PDF]
The Journal of Physical Chemistry AHerein, we reinvestigate the photophysics of ovalene, a prototypical nanographene for which conflicting spectroscopic results have been reported. Owing to its structural similarity and its identical D2h point-group symmetry, ovalene can essentially be viewed as a larger pyrene. We show that its optical transitions can be understood using the same model

Synthesis and Photophysics of 5-(1-Pyrenyl)-1,2-Azoles
ChemistryTwo pyrene derivatives, substituted at position 1 with isoxazole or NH-pyrazole, were synthesized in 85–87% yield starting from 1-acetylpyrene and via the cyclocondensation reaction of a β-enaminone intermediate with hydroxylamine or hydrazine.

Photophysics and Photochemistry of Naphthoxazinone Derivatives [PDF]
The Journal of Organic Chemistry, 2008 The photophysics and photochemistry of a series of naphthoxazinones have been studied using a combination of methods ranging from steady-state and time-resolved spectroscopic techniques to product analysis. The photophysics of naphthoxazinone derivatives is very dependent on the structure: phenanthrene-like compounds exhibit higher fluorescence quantum

Tb3+ Photophysics: Mapping the radiative and non-radiative transition probabilities of [Tb(H2O)9]3+ using molecular photophysics [PDF]
, 2022 The study of optical transitions in lanthanides has evolved separately from molecular photophysics. However, the forbidden transitions can be accurately described using the framework developed in molecular photophysics.
