Organic semiconductors are advanced functional materials, for nextgeneration optoelectronic devices. Here, we report the optical properties of neutral metal-organic complexes with two pincer-type bis(8- quinolinyl)amide (BQA) ligands. In particular, we analyse a series of transition-metal-BQA-complexes where the central metal atom is varied by photoluminescence and absorption spectroscopies. Prominent optical transitions are observed in the spectral range between 350nm and 900nm. The transition energies depend on the central metal atom of the BQA complexes, namely Zn, Fe, Mn or Cr. The measurements are analysed in the frame of configuration coordinate models. Our results show that the materials are suitable for organic semiconductors and organic solar cell application.
