Abstract

The UV-vis absorption properties of undoped and doped 1,4-phenylenemethylidynenitrilo-1,4-phenylenenitrilomethylidyne (PAZ) in various temperatures are reported. It is demonstrated that the absorption spectra can be modified not only by changing the temperature from 193 K to 413 K, but also via acid-base doping involving the protonation of nitrogen atom in imine group. The use of special protonating agent, i.e. 1,2-(di-2-ethylhexyl)ester of 4-sulfophthalic acid (PSA) lead to the modification of the absorption spectrum of the PAZ. The imine band in UV-vis spectrum of the doped with the PSA polyazomethine is 85 nm red shifts in comparison with unprotonated one. The thermochromism of PAZ included the conformational changes in the conjugating backbone structure of the undoped and doped polyazomethine. © 2009 Elsevier B.V. All rights reserved.
