| description | Due to the partially reduced π-conjugation of the fullerene cage, multi-functionalized fullerene derivatives exhibit remarkable fluorescent properties compared to pristine fullerenes, which have high potential for application in organic light-emitting diodes (OLEDs). In this study two multi-functionalized C
derivatives, C
(OCH
)
[C(COOEt)
] and C
(OCH
)
[C(COOEt)
]
, with excellent fluorescence properties, were designed and synthesized. Compared with C
(OCH
)
containing a single kind of functional group, both the C
(OCH
)
[C(COOEt)
] and C
(OCH
)
[C(COOEt)
]
exhibited enhanced fluorescence properties with blue fluorescence emission. The fluorescence quantum yields of the C
(OCH
)
[C(COOEt)
] and C
(OCH
)
[C(COOEt)
]
were 1.94% and 2.30%, respectively, which were about ten times higher than that of C
(OCH
)
. The theoretical calculations revealed that the multi-functionalization of the C
increased the S
-T
energy gap, reducing the intersystem crossing efficiency, resulting in the higher fluorescence quantum yield of the C
derivatives. The results indicate that multi-functionalization is a viable strategy to improve the fluorescence of fullerene derivatives. |
