STRUCTURE DETERMINATION IN THE TWILIGHT REGION BETWEEN MONOLAYERS AND 3-D CRYSTALS - A GRAZING-INCIDENCE X-RAY-DIFFRACTION STUDY OF NANOCRYSTALLINE AGGREGATES OF ALPHA,OMEGA-DOCOSANEDIOL AT THE AIR-WATER-INTERFACE

Double layers are formed by α,ω‐docosanediol (C22 diol) when it is spread on a water surface. The space group (a slightly relaxed form of P21/a) and the lattice parameters of the unit cell were determined by X‐ray diffraction. Furthermore, multilayer formation was inhibited by addition of 10% of C24H49OH or 5% of HO(CH2)22OCH2Ph to the spreading solution. The coverage with the double layer was reduced to less than 15%; the rest was occupied by a monolayer. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
