CONTROLLED SYNTHESIS OF NEW COMPOUNDS USING MODULATED ELEMENTAL REACTANTS

The design of modulated elemental reactants permits synthetic solid st ate chemists to control reaction intermediates. This has resulted in t he synthesis of new binary and ternary compounds which are thermodynam ically unstable relative to disproportionation into known compounds. T he ability to control composition as a function of distance in one dir ection in these reactants permits the synthesis of crystalline superla ttices.
