前驅(qū)體

Rare earth luminescence materials of alkaline earth stannates have also been prepared via thermal decomposition of hydroxo stannate precursors. 利用某些新型帶羥基的堿土錫酸鹽作為前驅(qū)體，固相反應(yīng)合成摻稀土的錫酸鹽發(fā)光材料。

The two cyclopentadienyl groups in metallocence compexes can be linked by one or two bridging groups to form ansa-metallocence catalyst precursors. 摘要茂金屬化合物中兩個(gè)茂環(huán)可以通過(guò)一個(gè)或兩個(gè)橋基相連接，形成各種橋聯(lián)茂金屬催化劑前驅(qū)體。
