TI  - Azaacenes Based Electroactive Materials: Preparation, Structure, 
      Electrochemistry, Spectroscopy and Applications-A Critical Review.
LID - 10.3390/ma14185155 [doi]
LID - 5155
AB  - This short critical review is devoted to the synthesis and functionalization of 
      various types of azaacenes, organic semiconducting compounds which can be 
      considered as promising materials for the fabrication of n-channel or ambipolar 
      field effect transistors (FETs), components of active layers in light emitting 
      diodes (LEDs), components of organic memory devices and others. Emphasis is put 
      on the diversity of azaacenes preparation methods and the possibility of tuning 
      their redox and spectroscopic properties by changing the C/N ratio, modifying the 
      nitrogen atoms distribution mode, functionalization with electroaccepting or 
      electrodonating groups and changing their molecular shape. Processability, 
      structural features and degradation pathways of these compounds are also 
      discussed. A unique feature of this review concerns the listed redox potentials 
      of all discussed compounds which were normalized vs. Fc/Fc(+). This required, in 
      frequent cases, recalculation of the originally reported data in which these 
      potentials were determined against different types of reference electrodes. The 
      same applied to all reported electron affinities (EAs). EA values calculated 
      using different methods were recalculated by applying the method of Sworakowski 
      and co-workers (Org. Electron. 2016, 33, 300-310) to yield, for the first time, a 
      set of normalized data, which could be directly compared.
