    Abstract: 樹狀高分子,是一種新穎且可能展現具有奈米分子特性的材料。由於樹狀高分子可能擁有內部架構與表層官能基團的不同化學結構,因此同時展現總體的與奈米界面的特性。因為有機溶劑對離胺酸的溶解度受限制,使得合成樹狀聚離胺酸更為複雜與困難。本研究計畫根據先期的研究成果,選擇雙成分的混合溶液系統當作溶劑,探討影響離胺酸聚合反應的熱力學的因素與動力學的機制,例如溫度、濃度、反應時間、加入的除水反應化合物等。以不同的反應聚合方式,例如批式與半批式的反應聚合方式,以及使用對於官能基的保護、去保護的步驟等,來合成樹狀聚離胺酸高分子。其化學結構與反應的分析是使用FTIR、NMR等儀器。物理性質與形態結構的檢測,則利用SEC、動態光散射、FESEM、TEM、DSC等。本研究的主要目標是要建立樹狀聚離胺酸高分子與其衍生化合物的合成技術,分子量與其分布的控制,樹狀化學結構的完整性等的探討。
    Dendrimer is a novel type of polymer that may impart nano-scale functionality. Polymers that contain functional moieties at its outer layer structure may have both bulk and interfacial properties. Since lysine is nearly immiscible in organic solvent except water, the polymerization of lysine was not easily accessible. According to our previous work result, we will employ binary solvent mixture to study the thermodynamic parameters and kinetic factors of the polymerization of lysine. The reaction behavior in batch and semi-batch process will be investigated. As semi-batch process is concerned, "protection" and "de-protection" will, in addition, be applied to terminal amines following each batch step. The analysis of chemical structure and reaction will be observed by using FTIR and NMR etc. Physical properties and morphology of dendrimers will be characterized by SEC, dynamic light scattering, FESEM, TEM and DSC measurement.
