Patent ID: 8236867

Claim:
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 similar affinity to a guest molecule, wherein the polymer complex comprises an aromatic compound having 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; wherein the aromatic compound ligands are aromatic compounds represented by the following formula (1); wherein the central metal is at least one selected from zinc, copper, nickel, cobalt, iron and silver; wherein the uncoordinating aromatic compounds have, at one or more positions on the aromatic ring of aromatic compounds selected from the following formulae 5( a ) to 5( i ), the position or positions being the same between the uncoordinating aromatic compounds forming the stack structure, substituents A of at least one kind selected from —CH 2 —OH, —CH 2 CH 2 —OH, —OH, —CH 2 —NH 2 , —CH 2 CH 2 —NH 2 , —NH 2 , —CH 2 —NO 2 , —CH 2 CH 2 —NO 2 , —NO 2 , —CH 2 —CH 3 , —CH 2 CH 2 —CH 3 , —CH 3 , —CH 2 CH 2 —OCOCH 3 , —CH 2 CH 2 —OCOCH 3 , —OCOCH 3 , —O—CH 3 , —O—CH 2 CH 3 , —S—CH 3 , —S —CH 2 CH 3 , —O—CH 2 CH 2 —OH, —CH 2 —CHO, —CH 2 CH 2 —CHO, and —CHO, the substituents A being the same between the uncoordinating aromatic compounds forming the stack structure and the substituents A are arranged regularly such that the substituents A are directed to the inside of a specific channel group B out of the two or more kinds of channel groups; and wherein the method comprising the steps of: including the guest molecule in the channel of the channel group B in which the substituents A are 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; wherein Ar is a structure having an aromatic ring; X is a divalent organic group or a single bond through which Ar and Y are directly bound to each other; Y is a coordinating atom or a coordinating atom-containing atomic group; n is a number of 3 to 6; and a plurality of Xs contained in one molecule may be different from one another, and a plurality of Ys may be different from one another
