Published: August 2022

Structural isolation of two unprecedented AIEE/ACQ type fluorophores based on -methyl N-confused tripyrromonomethene analogues exhibiting selective F anion-coordination-induced-enhanced emission (ACIEE) with a detection limit of 10 M is reported. The intrinsic relation between molecular structures/molecular arrangements with (without) anion binding have been revealed at a deeper level spectroscopic measurements and DFT level theoretical studies.
