As A Result Two Series Of Carbosilane Dendrimers With Doubled Node-To-Node Distance,From Previously Achieved,Were Synthesized Which. Differed By The Distribution Pattern Of Terminal Allyl Groups. A Sixth Generation Dendrimer With Varied Node-To-Node Distance In The Core And Periphery Had Been Synthesized. These Compounds Were Isolated By Preparative Lc And Were Characterized By H-1,C-13,And Si-29 NMR,Mass Spectroscopy,And Gpc. Their Characteristic Viscosities And Hydrodynamic Diameters Were Identified. A Comparative Analysis Of Properties Of Synthesized Dendrimers And Their Counterparts From Half The Distance Between The Branch Nodes Had Been Performed. Doi:10.1021/ma300957D

专利号:US-8951728-B2 优先权日:2004-11-22 标 题:Template directed split and mix synthesis of small molecule libraries 发明人:RASMUSSEN PETER BIRK 权利人:CHEMGENE HOLDING APS 摘要:The invention combines the advantages of split and mix synthesis with the advantages of template directed synthesis. The method comprises the steps of: a) adding a linker molecule L to one or more reaction wells; b) adding a molecule fragment to each of said reaction wells; c) adding an oligonucleotide identifier to each of said reaction wells; d) subjecting said wells to conditions sufficient to allow said molecule fragments and said oligonucleotide identifiers to become attached to said linker molecule, or conditions sufficient for said molecule fragments to bind to other molecule fragments and sufficient for said oligonucleotide identifiers to bind to other oligonucleotide identifiers; e) combining the contents of said one or more reaction wells; and f) contacting the resulting bifunctional molecule(s) of step e) with one or more (oligonucleotide) templates each capable of hybridizing to at least one of the oligonucleotide identifiers added in step c).
