Base-induced multi-state fluorescence of a trefoil-shaped salicylaldehyde azine derivative

Abstract

Base-induced four-state fluorescence is demonstrated in a trefoil-shaped salicylaldehyde azine derivative bearing multiple acidic protons.

Magnifying the ESIPT process in tris(salicylideneanilines) via the steric effect – a pathway to the molecules with panchromatic fluorescence

“…50 Furthermore, there is evidence presented that the diastereoisomers interconvert under basic conditions due to the resonance effect observed for the deprotonated species. 39,46,51 Eventually, the verification of the aforementioned interconversion rate under ambient conditions could be achievable with dynamic high-performance liquid chromatography (DHPLC). 52…”
