NOVELTY - An azaborinine derivative, is new.    USE - The azaborinine derivative is useful as charge transport, semiconducting, electrically conducting, photoconducting or light emitting material in optical, electrooptical, electronic, electroluminescent or photoluminescent components or devices (claimed).    ADVANTAGE - The azaborinine derivative provides new organic electronic materials having similar properties as the known polycyclic aromatic, and offer a promising combination of cost reduction, high production throughput, low temperature deposition methods and in consequence ease of fabrication of electronic devices, particularly of large electronic devices which are otherwise difficult to produce, such as for example large television screens.    DETAILED DESCRIPTION - An azaborinine derivative having a structural unit of Formula (I-1 or I-2), is new.    A1,A2=mono- or polycyclic aromatic or heteroaromatic ring systems annealed to the neighboring azaborinine ring;    B1=a mono- or polycyclic aromatic or heteroaromatic ring system annealed to the two neighboring azaborinine rings;    Ar1,Ar2=aryl or heteroaryl; and    R1,R2=hydrogen, carbyl and hydrocarbyl; where A1, A2, B1, Ar1 and Ar2 may independently of each other be substituted or unsubstituted.    INDEPENDENT CLAIMS are included for:    (1) a mixture or a blend which comprises one or more azaborinine derivatives or polymers having semiconducting, charge transport, hole transport, electron transport, hole blocking, electron blocking, electrically conducting, photoconducting or light emitting properties;    (2) formulation which comprises the azaborinine derivative and an organic solvent;    (3) charge transport, semiconducting, electrically conducting, photoconducting or light emitting material which comprises the azaborinine derivative; and    (4) a component or device which comprises the azaborinine derivative, the component or device being selected from organic field effect transistors (OFET), thin film transistors (TFT), integrated circuits (IC), logic circuits, capacitors, radio frequency identification (RFID) tags, devices or components, organic light emitting diodes (OLED), organic light emitting transistors (OLET), flat panel displays, backlights of displays, organic photovoltaic devices (OPV), organic solar cells (O-SC), photodiodes, laser diodes, photoconductors, organic photodetectors (OPD), electrophotographic devices, electrophotographic recording devices, organic memory devices, sensor devices, charge injection layers, charge transport layers or interlayers in polymer light emitting diodes (PLEDs), Schottky diodes, planarizing layers, antistatic films, polymer electrolyte membranes (PEM), conducting substrates, conducting patterns, electrode materials in batteries, alignment layers, biosensors, biochips, security markings, security devices, and components or devices for detecting and discriminating DNA sequences.
