본 발명은 수용성 초고분자 백금 착화합물(water-soluble supramolecular platinum complexes) 및 그 제조방법에 관한 것이다.The present invention relates to water-soluble supramolecular platinum complexes and a method for preparing the same.

백금 착화합물은 백금 금속에 이온이나 분자가 배위결합한 백금 착이온을 포함하는 화합물을 의미하며, 최근에는 백금 착화합물의 항암효과 및 나노구조의 전도성으로 인하여 생의학 및 반도체 등의 여러 산업 분야에서 많은 관심의 대상이 되고 있다. Platinum complex compound refers to a compound containing a platinum complex ion in which ions or molecules are coordinated to a platinum metal. Recently, due to the anticancer effect and the conductivity of nanostructures, platinum complex compounds are of interest to many industries such as biomedical and semiconductors. It is becoming.

특히, 본 발명의 백금 착화합물 구조의 원조격인 마그너스 녹색 염(Magnus' green salt, [Pt(NH3)4][PtCl4])은 200년 전 처음으로 합성되었으며, Pt를 금속 주쇄(metallic main-chain)로 하여 자가 결합된 독특한 초분자 구조(self-assembled supramolecular structure)로 반-일차원 구조(quasi-one-dimensional structure)의 상대적으로 짧은 Pt-Pt 결합으로 반도체로서의 특성을 가진다. 그러나, [Pt(NH3)4][PtCl4] 및 이의 유도체인 [Pt(NH2CH3) 4][PtCl4]는 물 및 통상의 유기 용제에 불용성을 나타내었고, 이를 극복하기 위해 R로 헵틸(heptyl) 내지 테트라데실(tetradecyl) 범위의 알킬기를 포함하는[Pt(NH2R)4][PtCl4] 유도체들이 연구되었으나, Pt-Pt사이의 공간이 넓어짐으로 인해 녹색 염 고유의 성질을 잃고, 분홍색(pink salts)의 절연체가 되는 문제점이 발생하였다. 따라서, 이러한 물질들의 다양한 응용 가능성에도 불구하고 가공 및 산업화에 상당한 제약이 있어 왔다(M.Fontana 외, Chem. Mater., 14, 1730-1735, 2002).In particular, Magnus' green salt ([Pt (NH 3 ) 4 ] [PtCl 4 ]), which is a precursor of the platinum complex structure of the present invention, was synthesized for the first time 200 years ago. It is a unique self-assembled supramolecular structure that is self-assembled as a chain, and has a relatively short Pt-Pt bond of a quasi-one-dimensional structure. However, [Pt (NH 3 ) 4 ] [PtCl 4 ] and its derivatives [Pt (NH 2 CH 3 ) 4 ] [PtCl 4 ] showed insolubility in water and common organic solvents. Although derivatives of [Pt (NH 2 R) 4 ] [PtCl 4 ] containing alkyl groups in the range of heptyl to tetratradecyl have been studied, the nature of green salts is due to the widening of the space between Pt-Pt. The problem of losing the salt and becoming an insulator of pink salts occurred. Thus, despite the wide range of applications of these materials, there have been significant limitations in processing and industrialization (M. Fontana et al. , Chem. Mater. , 14, 1730-1735, 2002).
