Followed by the massive production of buckminsterfullerene $C_{60}$, intensive efforts are being devoted to study on the superconducting, optical, and other interesting properties. Especially, the control of such properties are obtained by reducing dimensionality from bulk material using host-guest chemistry. A general methodology to gain isolated molecules consists of confined guest embedded within a rigid solid matrix, such as zeolites. In the present work, $C_{60}$ was incorporated to cavity or channel structure of Y zeolite and mesoporous molecular sieve MCM-41 with various internal surface environments by vapor phase impregnation method. The amount of incorporated $C_{60}$ in pure silica MCM-41 and Al implanted MCM-41 is negligible, but the amount of incorporated $C_{60}$ is considerable in the case of Cu ion-exchanged AlMCM-41. From these results, it is indicated that it is hard to incorporate $C_{60}$ within MCM-41 without existence of chemical attraction, in spite of the larger channel diameter of MCM-41 than the diameter of $C_{60}$. In addition, the incorporation of $C_{60}$ to considerable amount within the cavity of Cu ion-exchanged Y zeolite is also difficult. And it means that, in spite of the chemical attraction, it is hard to incorporate $C_{60}$ in the smaller cavity than the diameter of $C_{60}$ due to the spatial hinderance. The nature of the chemical attraction is revealed by XANES. The formation of charge-transfer complex, $Cu^Ⅱ_C_{60}^-$, by the electron transfer from $Cu^Ⅰ$ to electronegative $C_{60}$, is the main key of incorporation process of $C_{60}$ within Cu ion-exchanged AlMCM-41. The spatial comfortableness and the chemical attraction are simultaneously necessary for incorporation of $C_{60}$.
