Structural investigation of phthalocyaninatopoly(siloxane) Langmuir–Blodgett films by X‐ray diffraction

Abstract: The structure of Langmuir-Blodgett (LB) films of a rigid rod phthalocyanatopoly(si1oxane) substituted by alkoxy side chains has been investigated by X-ray diffraction using thin silicon wafers as a substrate for deposition. Freshly prepared samples do not possess a truely periodic multilayer structure.The polymer backbones lie flat in the substrate plane and are preferentially oriented along the dipping direction. Each macromolecule is surrounded by parallel adjacent rods and a firstneighbor distance is found … Show more

“…[13][14][15][16][17][18][19][20] The synthesis of these interesting polymers was substantially improved by Caseri and Sauer; [14,16,17] and according to their work large degrees of polymerization can be reached. The close cofacial packing of the monomer units along the polysiloxane chain which is sketched in Figure 2 leads to a strong interaction between repeat units and results in a Si-O-Si bond angle of 1808.…”

“…The cause for the varying intensity at 1166 cm -1 is probably a preferential orientation parallel to the surface. [5,6] The FT-IR spectrum of 2 strongly differs in the vibration at 1 056 cm -1 . The high intensity with 90 8 polarised radiation and the low intensity with 0 8 polarised radiation are probably due to a preferential orientation parallel to the surface as well.…”

“…These hairy-rod cellulose polymers are able to form mono-and multilayers on hydrophobic surfaces. [5][6][7][8] It was possible to obtain regenerated cellulose with high biocompatibility by hydrolysing cellulose silylesters. [5] In cooperation with the group of Wegner, [9] we first synthesised hairy-rod molecules for LB-layers on the basis of butyl cellulose substituted with phosphoric acid groups but having a low degree (0.2) of substitution only.…”
