The invention relates to a method for preferably adiabatic nitration of nitratable aromatic organic compounds (aromatics) and to a corresponding plant, in particular a production plant (nitration plant) for carrying out said method.

Process and plant for the adiabatic nitration of aromatic compounds

The invention describes electronic devices comprising a metal complex compound having at least one tetradentate ligand having N and/or P donors, in particular a ligand having a PPPP, NNNN, PNNP or NPPN structure, and uses of a complex of this type in the electronic field and for the generation of light.

Complex compounds having tetradentate ligands and the use thereof in the opto-electronic field

The invention describes electronic devices comprising a metal complex compound having at least one ligand containing an N donor and a P donor having the formula (I), in which the carbons C1 and C2 are part of an aromatic or non-aromatic ring system F1, P and N are phosphorus and nitrogen, where the nitrogen is in sp2-hybridized form, the radicals R3 and R4 are, independently of one another, hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, alkylcycloalkyl, heteroalkyl, heterocycloalkyl, heteroalkylcycloalkyl, aryl, heteroaryl, aralkyl or heteroaralkyl radical having up to 40 C atoms, and R1 and R2 are, independently of one another, an atom or radical from the group comprising hydrogen, halogen, R, RO&#x2014;, RS&#x2014;, RCO&#x2014;, RCOO&#x2014;, RNH&#x2014;, R2N&#x2014;, RCONR&#x2014; and &#x2014;Si(R)X(OR)3-X, where R=an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, alkylcycloalkyl, heteroalkyl, heterocycloalkyl, heteroalkylcycloalkyl, aryl, heteroaryl, aralkyl or heteroaralkyl radical having up to 40 C atoms and X=1, 2 or 3. The invention furthermore describes a process for the production of an electronic device of this type and processes for the generation of light or blue emission using a metal complex compound of this type.
