The modification of noble metal surfaces by organosulfur self-assembled monolayers (SAM) is a widely studied topic in the field of organic optoelectronics. The assembly of such monolayers alters the electronic structure of the metal surface and strongly affects thin film growth of subsequently deposited organic material employed in optoelectronic devices. Here we present the impact of SAMs on the crystal growth of 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine (bpytz). Tetrazines are promising candidates as alternative active materials for optoelectronic and sensor applications as they generally provide a high electron affinity. This study compares the growth of bpytz on pure Au(111) surfaces with modified gold surfaces employing decanethiol and didecyl-dithiocarbamates as self-assembling monolayers. X-ray diffraction (XRD) and Infrared (IR) spectroscopy are employed to investigate the different growth scenarios, while density functional theory (DFT) was utilized to analyze the measured IR data.
