The present invention is to provide a method for chemically modifying the inner surfaces of channels capable of further regulating characteristics of the internal environment of channels, by forming a polymer complex having a specific channel group B, the channel environmental characteristics of which are regulated by a specific substituent A, followed by utilizing the channels of the channel group B as a reaction field to convert the substituent A to a different substituent, and also to provide a polymer complex having highly specific channel environmental characteristics obtained by the chemical modification method. A method for chemically modifying inner surfaces of channels of at least one kind of channel group in a polymer complex provided with two or more kinds of channel groups each composed of channels identical with one another and having inherent affinity for a guest molecule, wherein the polymer complex comprises an aromatic compound; has two or more coordinating sites as a ligand, a metal ion as a central metal, and an uncoordinating aromatic compound, has a three-dimensional lattice-like structure containing a stack structure comprising the uncoordinating aromatic compound intercalated between aromatic compound ligands in a three-dimensional coordination network formed by coordinating the aromatic compound ligands to the central metal ion, and is provided with two or more kinds of the channel groups in the three-dimensional coordination network, and the uncoordinating aromatic compound has a specific substituent A at a specific position on the aromatic ring thereof, and is arranged regularly such that the substituent A is directed to the inside of a specific channel group B out of the two or more kinds of channel groups, the method comprising the steps of: including the guest molecule in the channel of the channel group B in which the substituent A is arranged; and reacting the guest molecule with the substituent A in the channel to convert the substituent A to a substituent A′, and to arrange the substituent A′ regularly directing to the inside of the channel of the channel group B or any channel of other channel groups.
