Ionothermal condensation-polymerisation of dicyandiamide was first performed by Bojdys et al., and later, Wirnhier et al. solved the structure of the product as poly(triazine imide). While the structure of this material was examined in detail, the electronic properties of this system have not been studied thoroughly yet. We find that the reduction of the temperature increases the structural order and preserves a desired CN-ratio. This enables us to harness the semiconducting properties in simple prototype devices. To access quality markers for the obtained product we applied powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), X-ray Photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FT-IR), UV-Raman, solid state nuclear magnetic resonance spectroscopy (ssNMR), UV-Vis absorption spectroscopy (UV-Vis), photoluminescence, and photoluminescence excitation spectroscopy (PL, PLE) as well as quantum yield and lifetime measurements. The observations of this work also are of explanatory value (i) for the wider organic materials community studying the effects of defects in conjugated polymer semiconductors and (ii) in the context of wide-spread studies into the photocatalytic activity of PTI.
