The given proposal describes the conceptualizaiton of a template assisted small molecule activation with s-/p-block bimetallics for the generation of novel main-group based materials.In a nutshell, the work programme can generally be divided into four parts. In the following, these are outlined precisely along the respective main aims.The first part will be the synthesis of s-block metal salts with weakly coordinating anions. This primarily includes the synthesis of the novel congener [Al(OTf)4]-, a weakly coordinating anion which is virtually unexplored regarding the stabilization of elusive main-group compounds. In the second part, it follows the attachment of low-valent group 13 element compounds to generate novel heterobimetallic compounds. The series of bimetallics which is about to be synthesized includes combinations of the ions Li+ - Cs+, Mg2+ - Ba2+ as well as the s-block related ion Zn2+ with Al(I) and Ga(I). Bimetallics as a function of homoleptic complexes are eventually used for the activation of small molecules in the third package. s-block mediation is used to enforce oligomerization reactions here following FLP chemistry such as with Ph-CN, Ph-NC, Ph-CNO, CO2 and further small molecules. With these main-group based macrocycles in hand, the synthesis of main-group materials is eventually scrutinized in base-induced ring-opening polymerization reactions as part of the fourth working package.

给定的提案描述了使用 s-/p-块双金属进行模板辅助小分子活化的概念，用于生成新型主族基材料。简而言之，工作计划通常可分为四个部分。下面，根据各自的主要目标精确概述这些内容。 第一部分是具有弱配位阴离子的s-嵌段金属盐的合成。这主要包括新型同系物 [Al(OTf)4]- 的合成，这是一种弱配位阴离子，在稳定难以捉摸的主族化合物方面实际上尚未被探索。在第二部分中，通过连接低价13族元素化合物来生成新型异双金属化合物。即将合成的双金属系列包括离子Li+-Cs+、Mg2+-Ba2+以及s-区​​相关离子Zn2+与Al(I)和Ga(I)的组合。作为均配配合物功能的双金属最终用于第三包中小分子的活化。 s-block 介导用于在 FLP 化学之后强制进行低聚反应，例如与 Ph-CN、Ph-NC、Ph-CNO、CO2 和其他小分子的低聚反应。有了这些基于主族的大环化合物，主族材料的合成最终将在碱诱导的开环聚合反应中进行仔细检查，作为第四个工作包的一部分。
