Tetrapyrazinoporphyrazines (TPyzPzs) bearing one, two, four or eight 3, 5‐di (tert‐butyl)‐4‐
hydroxyphenol moieties were synthesized as zinc (II) complexes and metal‐free derivatives …

The trace-oxygenated compounds in jet fuel reduce thermal stability. The identification and
quantification of oxygenated species is typically conducted using solid phase extraction …

In this work, the excited-state dynamics including intramolecular charge transfer (ICT) and
the redshift of C540A have been investigated in a series of solvents on the basis of the …

The time-dependent density functional theory (TDDFT) is used to investigate the effects of
solvent polarity and hydrogen bond on coumarin 500 (C500). Both the absorption maximum …

Formazan molecules exhibit photochromism because isomerization processes following
excitation may occur in both the azo group and the hydrazone group; thus, each formazan …

The intramolecular charge transfer (ICT) and twisted intramolecular charge transfer (TICT)
processes of coumarin 307 (C307) in different solvents were investigated by performing …

Fluorescence quenching of rhodamine 6G by graphene oxide (GO) was investigated using
steady‐state fluorescence spectroscopy and ultrafast time‐resolved absorption …

For the first time, vibronic coupling was considered when analyzing the excitation of
coumarin C102. It was found that the M05 functional in combination with the 6–31++ G (d, p) …

In the field of failure analysis and in particular molecular and particulate contamination,
being able to detect any trace of contaminants during the integration of an orbital spacecraft …

In a previous study, we reported a striking observation that photoinduced electron transfer
(PET) from aniline (AN) to photoexcited coumarin 102 (C102) can be accelerated by adding …
