Abstract We examine the dependence of polycyclic aromatic hydrocarbon (PAH) band intensity ratios as a function average number carbon atoms and assess their effectiveness tracers for PAH size, utilising data, models, tools provided by NASA Ames Infrared Spectroscopic Database. To achieve this, we used spectra from mixtures PAHs different ionisation fractions, following size distribution. Our wo...

Topologically divers PAHs with planar, twisted and negatively curved topologies were obtained from polycyclic phospholes using pericyclic reactions.

Polycyclic aromatic hydrocarbon chromophores that show an ideal bipartition between fluorescence and singlet oxygen production have been developed.
