Absorption Spectra of Exciplexes
TLDR
In this paper, the exciplex absorption spectra of pyrene, anthracene, biphenyl, and naphthalene with diethylaniline (DEA) as a common electron donor are recorded by applying pulse laser photolysis.Abstract:
Absorption spectra of the exciplexes of pyrene, anthracene, biphenyl, and naphthalene with diethylaniline (DEA) as a common electron donor are recorded by applying pulse laser photolysis. The numerous bands appearing in the spectra are analyzed and attributed to transitions from the emitting charge‐transfer state, (A−D+), to higher excited charge‐transfer states [(A−*D+) and (A−D+*)], as well as to locally excited states [(A*D) and (AD*)]. The results indicate that exciplex absorption spectroscopy may provide a new route to the experimental observation of excited molecular states (of D or A), which are not detectable in the ground state spectra of the corresponding molecules.read more
