Adiabatic deprotonation as an important competing pathway to ESIPT in photoacidic 2-phenylphenols
(Royal Society of Chemistry, 2019-05)
ESIPT (Excited State Intramolecular Proton Transfer) to C atom in 2-phenylphenol is known to be an intrinsically inefficient process. However, to the best of our knowledge, a structure-ESIPT efficiency relationship has not ...
Impact of benzannulation on ESIPT in 2-(2′-hydroxyphenyl)-oxazoles: A unified perspective in terms of excited-state aromaticity and intramolecular charge transfer
(Royal Society of Chemistry, 2020-10)
Hydroxyphenyl-azoles are among the most popular ESIPT (Excited State Intramolecular Proton Transfer) scaffolds and as such, they have been thoroughly studied. Nevertheless, some aspects regarding the interplay between the ...

Synthesis and luminescent properties of new naphthoquinoline lactone derivatives
(2020-11-01)
The multicomponent reaction between tetronic acid (1), 2-aminoanthracene (2) and aromatic aldehydes (3) and the subsequent addition of DDQ produced a series of naphtho [2,3-f]quinoline lactone derivatives (5) in good yield. ...
Highly solvatochromic 7-aryl-3-hydroxychromones
(American Chemical Society, 2012-04)
Introduction of the dialkylaminophenyl group in position 7 of 3-hydroxychromone changes the orientation of the excited-state dipole moment and leads to superior solvatochromic properties (>170 nm emission shift in aprotic ...
