Single-molecule electronic components (SMECs) are envisioned as next-generation building blocks in quantum circuit systems.However,challenges such as the reproducibility of the electrode attachment to the individual molecules hamper their fundamental investigation. Foro ur purpose,w ei ntroduced quasi optoelectronic electrodes (QOEs) that allowf or rapid investigations of the properties and suitability of compounds for molecular electronic devices.I np articular,w e probed hexa-peri-hexabenzocoronene (HBC) as am odel system for D 6h -symmetrical nanographenes,w ith porphyrins as QOEs attached to the periphery.Weprepared selectively bisporphyrin-functionalized HBCs with ortho-, meta-and parasubstitution and studied their communication properties,i n correlation to the geometrical alignment and size of the system, by electrochemistry and optical spectroscopy. Further insights into structure-property relationships were gained by DFT calculations and X-raydiffraction analysis.
