Studies have been made of Y-type and alternate layer (ABABA superlatti
ces) multilayer LB films using an iridium alkoxystilbazole metallo-org
anic complex. Surface potential analysis demonstrates the polar nature
of the metallo organic LB monolayers, ABABA structures of the iridium
alkoxystilbazole (B) and polysiloxane (A) materials exhibit significa
nt pyroelectric activity, This activity can be modified with exposure
to elevated temperature for short periods prior to pyroelectric assess
ment.
