TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The heterogeneous transition metal complex catalyst containing transition metal complex is supported by a support. The homogeneous transition metal complex catalyst and the heterogeneous transition metal complex catalyst comprise late transition metal. The active group has an atom chosen from lithium, magnesium, zinc, boron and group-14 element of periodic table.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The monomer is conjugated compound or aromatic compound. The aromatic compound is condensed aromatic compound, or aromatic compound having 2-4 active groups. When 5 ml hexane solution as developing solvent containing 1 g aromatic compound is charged in a column containing 50 mL hexane solution, 20 g silica gel having particle size of 63-210 mu m and 2 g anhydrous potassium carbonate, and having internal diameter of 15 mm and length of 5 cm, then the ratio of sum total of active group-containing aromatic compound in the solution which is passed to the column at room temperature for 3 minutes is 5 mol% or more with the aromatic compound before charging in the column. The active group-containing aromatic compound is of formula (I) or (II), preferably of formula (Ia) or (IIa).R1,R2=H, halo, or alkyl, alkenyl, aromatic group or alkynyl (all optionally substituted);R33+R1,R34+R2,R33+R34=ring;R34,R33=H, halo, or organic group has an atom chosen from group-14 element of periodic table;R34+R33=ring;X1,X2=active group;X12,X13=atom chosen from group-16 element of periodic table;X14=group connecting conjugated system of two 5-membered ring, or direct bond;andring C'=optionally substituted ring, 5-membered or 6-membered monocyclic ring or ring formed by condensing 2-6 rings.The monomer is of formula (i)-(iv).X3,X4=halo, alkyl sulfonyloxy, or arylsulfonyloxy;R31,R32=H, or 1-20C hydrocarbyl, 2-20C aryl, acyl, alkoxy or aryloxy (all optionally substituted);R25,R26=H, halo, or 1-20C hydrocarbyl, 2-20C heteroaryl or acyl (all optionally substituted);R27,R28=H, halo, or 1-20C hydrocarbyl, and 2-20C heteroaryl (all optionally substituted);Y'1,Y'2=atom chosen from group-15 element of the periodic table;R19,R20=H, halo, or optionally substituted 1-20C hydrocarbyl;Y'3,Y'4=N or (C(R43)) having substituent;R43=H, halo, or 1-20C hydrocarbyl, 2-20C heteroaryl (all optionally substituted);andR21,R22=H, halo, or 1-20C hydrocarbyl and 2-20C heteroaryl (all optionally substituted).The active group-containing aromatic compound is bonded with aromatic heterocyclic ring.
