Substituted position effect on twisted intramolecular charge transfer of 1- and 2-anthracene aromatic carboxamides as chemosensors based on linear polyether.


Bi-chromophoric compounds linked to linear polyether N,N'-[oxybis(3-oxapentamethyleneoxy-2-phenyl)]-bis(1-anthracenecarboxamide) (1(4)) and its analogues (1(5), 2(4) and 2(5)) were synthesized. Their photochemical properties and complexation actions were investigated in acetonitrile. These fluoroionophores have shown weak emissions in the absence of guest… (More)
