The tetracyanoethylene oxide (TCNEO) functionalization of chemical vapor deposition grown large area graphene and graphite was performed using reaction of TCNEO with carbon surface in chlorobenzene. The successful functionalization has been confirmed by Raman and Auger spectroscopy, and by numerical modeling of the structure and vibrational modes of TCNEO-functionalized graphene. Raman spectra of TCNEO-functionalized graphene and graphite show several groups of lines corresponding to vibrations of attached carbonyl ylide. One of key signatures of TCNEO attachment is the high intensity Raman band at ~1450 cm, which represents the C-C=C in plane vibrations in functionalization-distorted graphene. Raman spectra indicate the existence of central (pristine) attachment of TCNEO to graphene surface.
利用四氰基环氧乙烷（TCNEO）与氯苯中碳表面的反应，对化学气相沉积生长的大面积石墨烯和石墨进行了功能化处理。通过拉曼光谱和俄歇电子能谱，以及对TCNEO功能化石墨烯的结构和振动模式进行数值模拟，证实了功能化的成功。TCNEO功能化石墨烯和石墨的拉曼光谱显示出几组对应于附着的羰基叶立德振动的谱线。TCNEO附着的一个关键特征是在~1450 cm处的高强度拉曼带，它代表了功能化扭曲石墨烯中的C-C=C面内振动。拉曼光谱表明TCNEO以中心（原始）方式附着在石墨烯表面。
