Influence from the free volume on the photoinduced birefringence in azocompound-containing polymers
(Amer Chemical Soc, 2014)
Influence from the free volume on the photoinduced birefringence in azocompound-containing polymers
(Amer Chemical Soc, 2006-07-11)
The photoinduced birefringence is analyzed in a guest-host azobenzene-containing polymer in the temperature range from 20 to 330 K. An anomalous behavior arises in the low-temperature range, suggesting strong influence ...

Complexation of AAPH (2,2′-azobis(2-methylpropionamidine) dihydrochloride) with cucurbit[7]uril enhances the yield of AAPH-derived radicals
(2023)
AAPH (2,2′-azobis(2-methylpropionamidine) dihydrochloride), a water-soluble azo compound is widely employed to produce peroxyl radicals for chemical and biological studies. This compound is shown herein to form a stable ...

Adsorptive stripping voltammetric behaviour of copper complexes of some heterocyclic azo compounds
(1992)
Controlled adsorptive accumulation of copper complexed with TAN, TAC, TAR and TAM (heterocyclic azo-compounds) on a static mercury drop electrode provides the basis for the direct stripping measurement of this element in ...
Environmental effects in nitroquinoline derivatives solutions: Solvatochromism, acid-base effect and ion-sensor investigation
(2021-07-05)
Since the first chemical fluorescent sensor reported in 1867, it has often been sought to find intelligent organic molecules that act as chemical sensors of high selectivity and sensitivity. In this process, the colorimetric ...
