Impact of Electronic Substitution and Planarization on the Photophysical Properties of 2‐(2′‐Hydroxyphenyl)benzoxazole or 2‐(2′‐Hydroxyphenyl)‐Dimethylindole

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 28, 25 July 2026.
We report the synthesis, structural characterization, and photophysical investigation of a series of Excited‐State Intramolecular Proton Transfer‐active HBO and HDMI derivatives. By varying heterocyclic cores, substituents, and ethynyl planarization, we establish structure–property relationships governing fluorescence behavior.

Synthesis and Properties of Cross‐Shaped Donor–Acceptor Dyes: Tunable Emission From Visible to Near‐Infrared in Solution and Solid‐State

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
A comprehensive investigation (synthesis, electrochemistry, photophysics, and theory) of seven new cross‐shaped dyes based on N,N,N’,N’‐tetraphenyl‐1,4‐phenylenediamine cores substituted with different electron‐withdrawing groups, reveals tunable emission properties spanning the visible to near‐infrared range, both in solution and in the solid state ...
