NOVELTY - Substituted tetraheterocyclic compounds (I) are new.    USE - (I) are useful in optoelectronic or electronic components, preferably organic light-emitting diodes, organic solar cells, dye-sensitized solar cells, batteries and accumulators, as an electric p-dopant for components for photocatalytic water splitting, organic diodes, organic field effect transistors, fuel cells, capacitors e.g. supercapacitors, electrochromic displays, energy storage systems, electronic-, optoelectronic- or magnetic data storage elements, magnets, in organic complementary metal-oxide-semiconductor (hybrid complementary metal-oxide-semiconductor), radio frequency identification device and in sensors, and as organic semiconductor materials, electrode materials, an electron transport material, a hole blocking material, a charge injection layer, a host material for emitter, electrode material, electrolyte, absorber and as emitter (claimed).    ADVANTAGE - (I) exhibit high reduction potential, improved thermal stability and diffusion stability, and can be prepared in a simple manner with less effort. The optoelectronic or electronic components exhibits low diffusion coefficient and long service life.    DETAILED DESCRIPTION - Substituted tetraheterocyclic compounds of formula (I) are new.    Y1, Y2 = =NCN-, =C(CN)2-, =C(CF3)R-, =C(C6F5)2-, =C(heteroaryl)2-, =C(CF3)2-, =C(CN)R- or =C(CN)(CF3)-;    R = H, halo, CN, NO2, nitroso, sulfamide, carboxy, 1-20C carbo-alkoxy, 1-20C sulfo-alkyl, sulfo-halo-, sulfonic acid, electron deficient (hetero)aromatic group, halocarbonyl, carbamoyl, formyl, amidine-formyl, 1-6C alkylsulfanyl, 1-20C alkylsulfonyl or optionally saturated or aromatic 1-20C hydrocarbyl (all optionally substituted by at least one R) or hydrocarbyl moiety of formula (II);    Xa-Xe = N or C (substituted by R21);    R21 = R;    X1-X4, X7-X14 = N or C (substituted by R1-R4 or R7-R14);    R1-R4, R7-R14 = H, halo, CN, NO2, nitroso, sulfamide carboxy, 1-20C carbo-alkoxy, 1-20C sulfo-alkyl, =O, sulfo-halo, halocarbonyl, carbamoyl, formyl, amidine-formyl, 1-6C alkylsulfanyl, 1-20C alkylsulfonyl or optionally saturated or aromatic 1-20C hydrocarbyl (all optionally substituted by R1-R4 or R7-R14);    X5 = C (substituted by R5 or R6), N or C=Y3 (IIa);    X6 = C (substituted by R5 or R6), N or C=Y4 (IIb);    R5, R6 = R1-R4 or R7-R14; and    Y3, Y4 = Y1, Y2.    Provided that when X5 is (IIa) and X6 is (IIb), then groups X11-X14 or groups X5, X6 and X11-X14 are not present in (I).
