Summary on Grant Application Form |
Solvothermal synthesis, in which an inorganic material is crystallised under mild conditions in the presence of a structure-directing agent such as a organic amine has been widely applied in oxide chemistry for the synthesis of zeolites and phosphates. Its use in sulphide chemistry is only just beginning to be explored. It is clear from the examples of the main-group sulphides which have been synthesised to date that they exhibit very diffe structural principles to their oxide analogues. Low-dimensional structures are more commonly observed and a range of novel chain-like structural n have been identified for the binary antimony sulphides. We seek to exploit this feature for the production of novel low-dimensional magnets and electronic materials. In order to achieve this aim, we will introduce transition-metal cations with partially filled valence orbitals into the primary meta sulphide bonding network of antimony sulphides. Selecting templating agents in a rational manner, we will, in the initial stages of the synthetic programme, use a pseudo-combinatorial approach rapidly to explore the wide range of reaction parameter space in a systematic way. This will ider optimum conditions for the synthesis of specific materials and will allow the synthetic programme to be subsequently targeted to the production of I samples for detailed structural characterisation and physical property measurements. We will also explore the use of H2S/Ar mixtures to carry out syntheses at higher pressures than are accessible by solvent vaporisation and to provide independent control of pressure at a given temperature.
