This paper explores both electric field poling of polymers and LBK deposition of intrinsic y polar polymer films containing the chromophoie in the main-chain, or accordion architecture (3a). Mainchain syndioiegic polymers and poled films constitute the first topic, followed by a second section that describes a bilayer approach to intrinsically polar films. 

While these initial experiments provided good evidence in support of this "molecular accordion" mechanism, many issues remained to be clarified. Here we examine the mechanism of the adsorption and docking of the polymers as they are added, below the LCST, to aqueous liposome suspensions. Special attention was paid to the role of the alkyl pendent groups during the adsorption process and to the importance of the physical state of tne lipid bilayer. These questions were addressed primarily through the use of fluorescence measurements with labeled polymers. Supportive evidence was provided by microcalorimetric studies.
