摘要/Abstract

金属有机化合物很少作为光热材料.报道一系列碳龙配合物的合成及其光热性能，将OsCl₂（PPh₃）₃与有机多炔碳链反应获得金属杂戊搭炔，再与末端炔烃发生[2+2]环加成反应得到此类碳龙配合物——锇杂戊搭烯并环丁二烯.这些共轭的金属杂环化合物在紫外-可见区具有宽吸收并表现出优异的光热性能，有望成为一类新型的光热材料.

A series of photothermal cyclobutaosmapentalenes with conjugated groups attached to the metallacycle were synthesized from the reaction of OsCl₂(PPh₃)₃ with an organic multiyne and PPh₃, followed by a[2+2] cycloaddition with terminal alkynes. These highly conjugated metallacycles showed broad UV-Vis absorption and good photothermal efficiency. These easily synthesized metallacycles represent a type of new photothermal material.
Key words: organometallics, metallacycle, photothermal
