| Outline of Final Research Achievements |
The research octane number was dramatically improved from a low research octane number(17%) to a high research octane number (>99%) using the activated crystals of pillar[6]arene. Colored crystals of pillar[5]arene containing one benzoquinone unit were found to exhibit alkane-shape-selective vapochromic behavior. Activated pillar[5]arene crystals, prepared by removing solvated methanol from pillar[5]arene crystals, changed color from dark-brown to light-red after exposure to linear alkane vapors; however, no color changes were observed on exposure to branched or cyclic alkanes. The activated pillar[5]arene crystals are immersed in melted PEO, causing the crystals to selectively take up PEO with high mass fraction. The high mass fractionation is caused by the greater number of attractive CH/π interactions between PEO C-H groups and the π-electron-rich 1D channel of
the pillar[5]arene with increasing PEO chain length.

ガソリングレードはガソリン中のイソオクタンとn-ヘプタンの混合物に対して測定されるオクタン価によって評価される。しかし、イソオクタンの沸点(99度)はn-ヘプタンの沸点(98度)とほぼ等しく、石油蒸留による分離は非常に困難であり、多くの製造工程が必要となる。本研究では17％イソオクタン蒸気を用いた場合には、＞99％純度にまでイソオクタンの純度を向上させることができた。
