Specific effects of the counter- ions (Na+, Cd²+, Pb²+, and Ba²+) and sub-solution pH on the monolayer collapse pressure, transfer efficiency and molecular order in the multilayers are found. A correlation between the monolayer properties and the ability for formation of periodic discotic structures in the presence of divalent counterions is established. The discotic molecules retain their "edge-on" arrangement in the highly compressed transferred films with slight irregular interdigtation of the flexible wings and inclination to the substrate normal. The tilt and the inter- digitation are reduced when the discotic monolayers are deposited in alternating LB films with barium arachidate spacer layers.}, language = {en} } @article{Brehmer1994, author = {Brehmer, Ludwig}, title = {D{\"u}nne organische Schichten : Anforderungen und M{\"o}glichkeiten f{\"u}r die Sensorik}, year = {1994}, language = {de} } @article{AngelovaIonovReicheetal.1994, author = {Angelova, Angelina and Ionov, Radoslav and Reiche, J{\"u}rgen and Brehmer, Ludwig}, title = {Head-to tail or head-to-head structure of Langmuir-Blodgett long chain ester multilayers?}, year = {1994}, language = {en} } @article{DietzelFreydankReicheetal.1995, author = {Dietzel, Birgit and Freydank, A. and Reiche, J{\"u}rgen and Brehmer, Ludwig and Knoblauch, H. and Knochenhauer, Gerald and Zetzsche, Thomas}, title = {Mono- und Multischichten von neuen aromatischen 1,3,4-Oxadiazolen}, year = {1995}, language = {de} } @article{PenacoradaDietelReicheetal.1995, author = {Penacorada, Florencio and Dietel, Reinhard and Reiche, J{\"u}rgen and Zetzsche, Thomas and Knobloch, Harald and Katholy, Stefan and Brehmer, Ludwig}, title = {Studium des Einflusses von Uranyl-Gegenionen auf die Struktur von Langmuir- und Langmuir-Blodgett Filmen der Arachins{\"a}ure}, year = {1995}, language = {de} } @article{BauerSchulzBrehmeretal.1995, author = {Bauer, J. and Schulz, Burkhard and Brehmer, Ludwig and B{\"o}tcher, M. and Jagdhold, U. and H{\"o}ppner, K. and Kulesch, A. and Dietzel, Birgit}, title = {Anwendung von Langmuir-Blodgett-Schichten als Resist f{\"u}r die Niederspannungs-Elektronenstrahl-Lithografie}, year = {1995}, language = {de} }
