No indene was found, clearly showing that indanes and indenes may originate from different precursors, and algae lived in saltwater are important contributors to the indanes.

没检测到茚类化合物，说明二氢化茚和茚可以源自不同的先质，生活于咸水环境的低等生物是二氢化茚类化合物的母质之一。

A series of the ligands including 6-bromo-piperonal dimethyl acetal, bis (9-fluorenyl) silane, and the dimer of indene have been synthesized and characterized.

合成了溴代胡椒醛二甲基缩醛基配体，合成了手性配体甲基苯基双芴基硅烷，合成了茚的二聚体，对其进行表征，培养单晶并测定了晶体结构。

The substituted half-sandwich titaconece with bulky alkoxyl group [CpTiC1〓 or CpTi 〓] or indene ring can not be fluorinated by BF〓·Et〓O under the selected condition, but still coordinates with the BF〓, this coordination then enhances the steric effect that stabilizes the precursor and hinders the reduction of the Ti to the Ti species, reflected in the decrease in polymerization activity.

但是这个转化受主催化剂分子的空间位阻和聚合反应温度的影响，当主催化剂为大位阻的烷氧基取代茂钛络合物或茚钛络合物时，在一般的聚合温度下BF〓不能对它们进行氟化，但可以和其中的OR配位，这种配位进一步加剧了空间位阻，从而阻碍了活性中心的形成，导致催化活性的下降。
