TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Structure: The three-dimensional network structure is complex three-dimensional network structure having two or more independent three-dimensional network structures. The complex three-dimensional network structure is mutually penetrating structure. Highest occupied molecular orbital (HOMO) of the non-coordinating aromatic compound and lowest unoccupied molecular orbital (LUMO) of the aromatic compound ligand have orbit-shaped overlap, and laminated structure is stabilized. Preferred Pore: At least one pore in pore group differs in size, shape and environment. A pore contained in pore group has an elongate channel shape. The diameter of the inscribed circle of the pore in a surface parallel to crystal plane closest to vertical with respect to the direction, in which the pore contained in the pore group extends, is 2-70 degrees A. The length of inscribed ellipse of the pore in a surface parallel to the crystal plane closest to vertical with respect to the direction, in which the pore contained in the pore group extends, is 5-70 degrees A. The breadth of the inscribed ellipse is 2-50 degrees A. Preferred Ligand: The aromatic compound ligand is an aromatic compound of formula (2): Ar-(X-Y')n, preferably tris (4-pyridyl) triazine. The non-coordinating aromatic compound is fused polycyclic aromatic compound, preferably a triphenylene derivative and/or a perylene derivative. The carboxylate-ester group has larger intermolecular interaction than van der Waals force.Ar=structure having aromatic ring;X=divalent organic group or single bond connecting Ar and Y' directly;Y'=coordinating atom, or group containing coordinating atom;andn=3-6. EXAMPLE - Palladium acetate (in mg) (81.2), 1,1'-bis(diphenyl phosphino)ferrocene (200.4), cesium fluoride (4890.7), 2-bromobenzoic acid ethyl ester (1662.7) and 2-(trimethyl silyl) phenyl trifluoro methane sulfonate (6448.5) were mixed in argon atmosphere, dehydrated with toluene and acetonitrile, and heat-stirred at 110 degrees C for 24 hours. Saturated salt solution was added to stop reaction and diethyl ether (250 mL) was added to separate organic layer. The organic layer was purified and 1-carboxy ethyl ester triphenylene (D1) (382.9) was obtained at yield of 17%. Nitrobenzene (4 ml) and methanol (0.5 ml) were added in test tube and 2,4,6-tris (4-pyridyl)-1,3,5-triazine (6.4) was dissolved. 1-Carboxy ethyl ester triphenylene (42) was added and solution obtained by dissolving zinc iodide (9.6) in methanol (1 ml) was added and stood at 23-25 degrees C for 3 days. Polymer complex (((ZnI2)3(C)2(D1))(nitrobenzene)4(methanol)n)z was obtained with favorable guest component conduction characteristics.
