Abstract
아다만탄 또는 β-cyclodextrin이 결합된 루테늄(II)-터피리딘 착화합물(8, 9, 11)을 합성하고 1H NMR, 13C NMR 및 질량분석스펙트럼으로 구조를 확인하였다. 아다만탄이 결합된 루테늄(II)-터피리딘 착화합물(8, 11) 은 물에 전혀 녹지 않으나, β-cyclodextrin 수용액에 혼합할 경우 β-cyclodextrin과의 초분자를 형성하여 물에 잘 녹아들어갔다. 비슷한 방법으로 수용액 중에서 루테늄(II)-터피리딘 착화합물(8, 11)을 각각 착화합물 9와 혼합 하였을 때, 착화합물(8, 11)의 아다만탄 부분이 루테늄 착화합물 9의 β-cyclodextrin 내부에 포접 됨으로써 안정 한 초분자를 형성하였다. Ru(II)-terpyridine complexes (8, 9, 11) linked with adamantyl or β-cyclodextrin moieties were synthesized and characterized based on their 1H and 13C NMR spectra as well as MS spectra. Ru(II)-terpyridine complexes (8, 11) linked with adamantyl moiety were readily dissolved in aqueous solution via encapsulation by β-cyclodextrin when they were mixed with an equimolar amount of β-cyclodextrin. In the similar way, the adamantane guest of the Ru(II)-terpyridine complexes (8, 11) were encapsulated by β-cyclodextrin moiety of the ruthenium complex 9 to afford supramolecular assemblies in aqueous environment. Formation of assemblies was corroborated by 1H NMR spectroscopy.
