Abstract (en)
[origin: WO2022090762A1] The present invention concerns dispiroindenopyridines and dispiroindenopyridazines and derivatives thereof, methods for their preparation, the study and definition of their properties, and their uses. In particular, the present invention relates to the preparation of new classes of heical molecules represented by the general formulae A) and/or A') and/or B) and/or B') for use in applications in the field of organic electronics, since they have proved to have greater and more advantageous properties in comparison with the other known organic molecules that may be taken into consideration as candidates for the same use.
