TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): The preparation of (I) comprises reacting a cis-indolocarbazole derivative with aryl or heteroaryl derivative, which is substituted in ortho-positions by halogen, preferably iodine, and an acid derivative, preferably a carboxylic acid ester, carboxylic acid halide, sulfonic acid halide, a phosphine halide or a phosphine oxyhalide. Preferred Components: (I) (81 general compounds given) is e.g. heterocyclic complex of formulae (XI to XVI). Preferred Definitions:    X = C=O or SO2.    SPECIFIC COMPOUNDS - 114 Compounds (I) are disclosed e.g. 8,16-diazaheptacyclo(14.9.2.0(2,7).0(8,26).0(9,14).0(17,22).0(23,27))heptacosa- 1(25),2(7),3,5,9(14),10,12,17(22),18,20,23,26-dodecaen-15-one of formula (Ia), 15-thia-8,16-diazaheptacyclo(14.9.2.0(2,7).0(8,26).0(9,14).0(17,22).0(23,27)) heptacosa-1(25),2(7),3,5,9(14),10,12,17(22),18,20,23,26-dodecaen-15-one, 15-thia-8,16-diazaheptacyclo(14.9.2.0(2,7).0(8,26).0(9,14).0(17,22).0(23,27)) heptacosa-1(25),2(7),3,5,9(14),10,12,17(22),18,20,23,26-dodecaen-15-one, 15-benzyl-8,16-diaza-15-phosphaheptacyclo(14.9.2.0(2,7).0(8,26).0(9,14).0(17,22).0(23,27)) heptacosa-1(25),2(7),3,5,9(14),10,12,17(22),18,20,23,26-dodecaen-15-one and 15-thia-8,16-diazaheptacyclo(14.9.2.0(2,7).0(8,26).0(9,14).0(17,22).0(23,27)) heptacosa-1(25),2(7),3,5,9(14),10,12,17(22),18,20,23,26-dodecaene-15,15-dione.    EXAMPLE - Methyl-2-iodobenzoate (27 ml) and 11,12-dihydroindolo(2,3-a)carbazole (37.4 g) were mixed with di-n-butyl ether (150 ml) and the solution was degassed. Then the mixture was mixed with copper powder (10 g), copper (I) iodide (1.38 g) and potassium carbonate (22 g) and stirred for 4 days under protective gas at 144 degrees C. The organic phase was dried over magnesiu8m sulfate and the solvent was removed under vacuum. The residue was recrystallized from acetone and finally sublimed under high vacuum to obtain 8,16-diazaheptacyclo(14.9.2.0(2,7).0(8,26).0(9,14).0(17,22).0(23,27))heptacosa- 1(25),2(7),3,5,9(14),10,12,17(22),18,20,23,26-dodecaen-15-one.
