【 摘 要 】

We set out to study the use of a series of ruthenocenes as possible and promising sources for ruthenium and/or ruthenium oxide film formation.The thermal stability of a series of ruthenocenes, including (η⁵-C₅H₄R)(η⁵-C₅H₄R´)Ru (1), R = R´ = H (3), R = H, R´ = CH₂NMe₂ (5), R = H, R´= C(O)Me (6), R = R´ = C(O)Me (7), R = H, R´ = C(O)(CH₂)₃CO₂H (8), R = H, R´ = C(O)(CH₂)₂CO₂H (9), R = H, R´ = C(O)(CH₂)₃CO₂Me (10), R = H, R´= C(O)(CH₂)₂CO₂Me (11), R = R´ = SiMe₃), (η⁵-C₄H₃O-2,4-Me₂)₂Ru (2), and (η⁵-C₅H₅-2,4-Me₂)₂Ru (4) was studied by thermogravimetry. From these studies, it could be concluded that 1–4, 6 and 9–11 are the most thermally stable molecules. The sublimation pressure of these sandwich compounds was measured using a Knudsen cell. Among these, the compound 11 shows the highest vapor pressure.
