ResumoSingle crystals of the organic compounds dioctadecyladipate (OAO, 2d = 93.8 Å), potassium acid phthalate (KAP, 2d = 26.6 Å) and thallium acid phthalate (TlAP, 2d = 25.9 Å) have been grown from solutions by the cooling method. The cooling rates are 0.03 to 0.05 °C/day for OAO and 0.15 to 0.25 °C/day for TlAP and KAP. An example of the application of a spherically bent OAO crystal as dispersing element for ultrasoft X-rays is given, showing a considerable increase in resolution compared to a grating measurement. On account of the high atomic number of Tl the TlAP crystal yields an intensity increase by a factor of 3.5 to 4 compared with KAP.
