Summary:The present invention relates to an organic-inorganic hybrid nanoporous silica material having high selectivity to particular metal ions, and a method for preparing the same. Specifically, the present invention provides an organic-inorganic hybrid nanoporous silica material and a method for preparing the same, wherein the organic-inorganic hybrid nanoporous silica material has a closed pore type by capturing a functionalized silane compound in a nanoporous silica material, which is surface-modified with a functionalized silane compound, using a cyclic molecule, and enables the sensing and highly selective adsorption of various metals due to the incorporation of an organic ligand capable of adsorbing metal ions in pores. La présente invention concerne un matériau à base de silice nanoporeux hybride organique-inorganique ayant une haute sélectivité vis-à-vis d'ions métalliques particuliers et un procédé pour la préparation de celui-ci. Plus précisément, la présente invention concerne un matériau à base de silice nanoporeux hybride organique-inorganique et un procédé pour la préparation de celui-ci, le matériau à base de silice nanoporeux hybride organique-inorganique étant de type à pores fermés par capture d'un composé silane fonctionnalisé dans un matériau à base de silice nanoporeux, qui est modifié en surface avec un composé silane fonctionnalisé, à l'aide d'une molécule cyclique, et permettant la détection et l'adsorption hautement sélective de divers métaux en raison de l'incorporation d'un ligand organique susceptible d'adsorber des ions métalliques dans des pores. 본발명은 특정 금속 이온에 대해 고도의 선택성을 가지는유기 -무기하이브리드나노 세공실리카 물질과 이의 제조방법에 관한 것으로보다구체적으로는기능화된 실란 화합물로 표면 개질된 나노세공 실리카 물질에 환형분자를 이용하여 기능화된 실란 화합물을 포집함으로서 막힌세공 (Closed pore)형태를가지며,세공내부에 금속이온을 흡착 할 수 있는 유기 리간드가 혼입되어 다양한 금속을 센싱 및 고택적인 흡착이 가능한유기 -무기 하이브리드 나노 세공 실리카 물질과 이의 제조방법을 제공하는 것이다.
