Synthesis of BN-Fused Polycyclic Aromatics via Tandem Intramolecular Electrophilic Arene Borylation
摘要:
A tandem intramolecular electrophilic arene borylation reaction has been developed for the synthesis of BN-fused polycyclic aromatic compounds such as 4b-aza-12b-boradibenzo[g,p]chrysene (A) and 8b,11b-diaza-19b,22b-diborahexabenzo[a,c,fg,j,l,op]tetracene. These compounds adopt a twisted conformation, which results in a tight and offset face-to-face stacking array in the solid state. Time-resolved microwave conductivity measurements prove that the intrinsic hole mobility of A is comparable to that of rubrene, one of the most commonly used organic semiconductors, indicating that BN-substituted PAHs are potential candidates for organic electronic materials.

Provided is an organic electroluminescent element which has improved driving voltage and improved current efficiency. An organic electroluminescent element having the above-mentioned improved characteristics is provided by using, as a material for organic electroluminescent elements, a polycyclic aromatic compound in which a nitrogen atom and another heteroatom or a metal atom (X) are adjacent to each other in a non-aromatic ring.
