Abstract

Sonochemical synthesis of fullerene oxides $[C_{70}O_n](n=1{\sim}2)$ by fullerene$[C_{70}]$ and metal hexacarbonyl complexes $M(CO)_6$(M=Cr, Mo, W) took place under air atmosphere. The reactivity of fullerene$[C_{70}]$ and several metal hexacarbonyl complexes $M(CO)_6$(M=Cr, Mo, W) under same ultrasonic condition increased in the order of $Mo(CO)_6$ > $W(CO)_6$ > $Cr(CO)_6$. The MALDI-TOF-MS, UV-visible spectra, and HPLC analysis confirmed that the products of sonochemical reaction were $[C_{70}O_n](n=1{\sim}2)$.

공기 중 초음파 조건에서 풀러렌$[C_{70}]$과 금속 헥사카르보닐 착물 $M(CO)_6$ (M=Cr, Mo, W)을 반응시켜 풀러렌 산화물 $[C_{70}O_n](n=1{\sim}2)$을 합성하였다. 동일한 초음파 조건에서 풀러렌$[C_{70}]$과 여러 가지 금속 헥사카르보닐 착물 $M(CO)_6$ (M=Cr, Mo, W)의 반응성은 $Mo(CO)_6$ > $W(CO)_6$ > $Cr(CO)_6$ 순으로 증가함을 나타냈다. MALDI-TOF-MS, UV-visible 스펙트럼과 HPLC를 사용하여 분석한 결과 초음파화학 반응의 생성물은 $[C_{70}O_n](n=1{\sim}2)$ 임을 알 수 있었다.
