Paragraph 0575; 0585-0588, (2018/05/09)
The present invention relates to organic compounds represented by any one of chemical formulas A to D, and an organic light-emitting diode comprising the same. In the chemical formulas A to D, X, R1 to R12, L1, L2, Ar1 to Ar3, n and m are as described in the specification of the present invention. The organic light-emitting diode comprising a compound represented by any one of the chemical formulas A to D may have higher efficiency and longer lifetime compared to the existing diode.COPYRIGHT KIPO 2018

Tributyltin hydride when reacted with a series of substituted azoarenes afforded hydrazo compounds with high chemoselectivity and good to high yields.With ortho-substituted azoarenes, mixtures of hydrazo derivatives and N-heterocycles or cyclic products only were obtained.The kinetic law of the process was determined in the presence and in the absence of AIBN; with the radical initiator the reaction proceeds via a radical chain mechanism, whereas without AIBN the presence of stannyl free radicals could be discarded.The mechanism of the noninitiated reaction is discussed.EPR characterization of spin adducts obtained by reacting group IVB organometallic radicals with azo compounds is reported.
