Anion binding by p-aminoazobenzene-derived aromatic amides: spectroscopic and electrochemical studiesElectronic supplementary information (ESI) available. See DOI: 10.1039/c7pp00245a
The synthesis and complexing properties of p -aminoazobenzene-derived mono-, bis-, and trisamides were described. Ligands 3 and 4 bind anions, including fluorides, chlorides, bromides, acetates, benzoates, dihydrogen phosphates, hydrogen sulfates, and p -toluenesulfonates, in chloroform forming 1 : ...

| Summary: | The synthesis and complexing properties of
p
-aminoazobenzene-derived mono-, bis-, and trisamides were described. Ligands
3
and
4
bind anions, including fluorides, chlorides, bromides, acetates, benzoates, dihydrogen phosphates, hydrogen sulfates, and
p
-toluenesulfonates, in chloroform forming 1 : 1 complexes. The highest value of stability constant was evaluated for the
4
-F
−
complex (log
K
= 5.63 ± 0.21). On the basis of
1
H NMR, and FTIR spectroscopy, the possible nature of the ligand-anion interactions was proposed. The
E
Z
isomerization process of tripodal amide
4
in chloroform was studied. The effect of anions on
Z
to
E
thermal back isomerization was investigated.
The synthesis and complexing properties of
p
-aminoazobenzene-derived mono-, bis-, and trisamides were described. Photoisomerization process was examined. |
