Solution-processable BODIPY decorated triazine photodiodes and their comprehensive photophysical evaluation

A solution-processed organic photodiodes can function as thin-film alternative for solid-state photosensor in various optoelectronic applications due to the physical and chemical tuneability. In spite of their unique structural, optical, and electronic properties, the development of BODIPY based organic phodiodes has lagged behind that of other luminescent chromophore units. Here, we demonstrate the design, synthesis, and characterization of two novel BODIPY decorated triazine tripods for next-generation solution-processed photosensor applications. The photophysical and thermal properties of the BODIPY decorated triazines were determined. Furthermore, the photo-electrochemical properties of newly synthesized compounds have been studied in detail using the photoconductivity measurement system. The potentials of the prepared diodes as sensors in solar tracking systems have been investigated. Also, quantum chemical calculations were applied to those compounds to examine effect of both OH group and different binding position on those compounds comparison with experimentally observed data. In addition, their photodiode properties were tested here. The obtained photoelectrical results indicate that BODIPY decorated triazine tripods based photodiodes can be used as a photosensor in optic control systems.
