In this article, we present pyroelectric investigations of electrically poled side-chain polymers containing mesogenic disazobenzene chromophores using a very simple setup. Heating above the glass temperature (about 104°C) usually eliminates the pyroelectric effect of the sample. However, in samples with an indium tin oxide/aluminum electrode design, a self-poling effect is observed. The pyroelectric coefficients of electrically poled samples reach values of up to 0.2 μC/(m2K). From this, we conclude that the strongly anisometric side chains can be reoriented, and that their degree of alignment is about 3%. © 2002 American Institute of Physics.
