本研究課題では, (1) ポリジアセチレン(PDA)ナノ結晶サイズの単分散化, (2) PDAナノ結晶のカプセル化, (3) パターン基板上でのカプセル化PDAナノ結晶の配列制御を行い, 超階層構造形成を研究目的とした. 本年度(最終年度)の研究成果を以下にまとめる.(1) 無脈流シリンジポンプを採用した再沈法を確立し, PDAナノ結晶の大量合成とサイズ・形状制御に成功した. 従来の再沈法に比較して約500倍のスケールアップとなった. (2) PDAナノ結晶のカプセル化に関しては, スチレンモノマー(ST)と2つの水酸基を有する水溶性・ノニオン性スチレン誘導体(M1)とのシード/乳化重合による共重合化(架橋剤DVBおよび重合開始剤KPSを使用)によって, ほぼ球形状のカプセル化に成功した. ポリスチレンシェル層の厚さは段階的にモノマー(ST/M1)を添加することにより制御可能であった. M1の代わりにカチオン性あるいはアニオン性スチレン誘導体を用いた場合は, カプセル化率の低下あるいは凝集体を与えた. PDAナノ結晶と水分散媒体および生成するポリスチレンとの親和性のバランスをM1が取っているものと推定され, カプセル化機構を提案した. (3) パターン基板を用いたTapered Cell法による超階層構造制御を試みた. 即ち, ピット内にポリスチレンラテックス(PSL)を, テラス上にカプセル化PDAナノ結晶を配列制御することに成功した. さらに, ピット内にカプセル化半導体微粒子を, 同様にテラス上にカプセル化PDAナノ結晶を配列制御できることも確認された. このようにカプセル化することにより, パターン基板上にPSL, PDAナノ結晶, 半導体微粒子と言った異種材料を効率的且つ位置選択的に積層・累積する基盤技術が確立された.

The main topics of this study are as follows: (1) the dispersion of PDA, (2) the crystallization of PDA, (3) the configuration of PDA crystals on the substrate, and the formation of the objective of the study. The research results of this year (the most recent year) are listed below. (1) the results of this year's research are as follows: (1) the results of the research results of this year (the most recent year) are as follows: (1) the results of the research results of this year (the most recent year) are as follows: (1) the results of the research results of this year (the most recent year) are as follows: (1) the results of the research results of this year (the most recent year) are as follows: (1) the results of the research in this year (the most recent year) are as follows: (1) the results of the research results of this year (the most recent year) are as follows: (1) the results of this year's (most recent year) research results are as follows. The re-sedimentation method is about 500 times higher than that of the previous method. (2) the structure of PDA is characterized by chemical reaction, and the acid base of water-soluble resin (ST) 2 is soluble in water, and the acid group (M1) has the property of water solubility. (M1) the overweight of the compound (M1) is the same as that of the emulsified superalloy (frame DVB starting with the use of KPS), and the ball shape is successfully transformed. The thickness of the thick section of the section (ST/M1) adds a lot of information to the control of the thickness of the segment. In M1 generation, the rate of coagulation is low, and the rate of coagulation is low. PDA simulation results show that the water dispersive media will generate information on the performance of the system and the performance of M1 on the presumption of the impact on the performance of the proposed mechanism. (3) the structure of the substrate is made by using the method of Tapered Cell. That is, you need to make sure that you have a lot of trouble (PSL), and you need to make sure that you are successful in the configuration of the PDA computer. In this paper, we use the same method to modify the semi-bulk particles, and make sure that the PDA crystals are used to make sure that the particles are in good condition. In order to improve the performance of the equipment, the PSL and PDA crystals are applied on the substrate, and the semiconductor particles are used to determine the yield rate of all kinds of materials and the location of the selected key technology.
