초록

96개의 allyl기를 가진 나무가지꼴 실란 거대분자를 alkenylation 과 hydrosilylation의 반복된 과정을 경유하여 매우 높은 수율로 합성하였다. 이 두 과정을 통해서 나무가지꼴 거대분자는 크로마토그래피법을 이용한 정제법(silica hel, chloroform)에서 순수한 물질을 얻어졌음이 $/_1/H,\;/_13/CNMR$과 원소분석 등에 의해 확인되었다.

Silane dendrimer with 96 allylic end groups has been synthesized in excellent yield using repetitive alkenylation-hydrosilylation cycles. Each of the two steps provided the products in almost quantitative yields. After a simple chromotograpic purification (silica gel, chloroform), pure dendrimers were obtained and their purity was checked with 1H, 13C NMR spectroscopic method and elemental analysis.
