Oxidative aromatic coupling occupies a fundamental place in the modern chemistry of
aromatic compounds. It is a method of choice for the assembly of large and bewildering …

Dyes having coumarin core which absorbs and emits in deep-red to NIR region have
become incredibly valuable due to their essential role in biology, DSSC, NLO materials, and …

Photosensitizers that display “unusual” emission from upper electronically excited states
offer possibilities for initiating higher-energy processes than what the governing Kasha's rule …

Die oxidative aromatische Kupplung nimmt einen grundlegenden Platz in der modernen
Arenchemie ein. Sie ist das Mittel der Wahl für den Aufbau großer, komplizierter …

Carbon dots have often been studied to investigate their unique optical properties such as
excitation wavelength-independence emission. Carbon dots have also been shown to …

Quadrupolar bis-coumarins bearing dialkylamino groups, prepared by a double Pechmann
reaction and subsequent oxidation, strongly emit yellow-orange light. Comparison with non …

The development of new n-type organic semiconductors is crucial to the development of
organic electronics. The introduction of heteroatoms into polycyclic aromatic hydrocarbons …

Eleven conjoined coumarins possessing a chromeno [3, 4-c] chromene-6, 7-dione skeleton
have been synthesized via the reaction of electron-rich phenols with esters of coumarin-3 …

By using 2-fluoro-substituted diaryliodonium salts, a novel benzocylization has been
