“bottom-up” approach, which offers a facile access to extended polycyclicaromatichydrocarbons with concave -surfaces, cove regions and zig-zag edges. The molecular structures as well as their optical and electrochemical properties were studied and compared with DFT calculations. Such contorted molecules serve as model systems to study the influence of the curvature and edge structures on the physical and
An organic semiconductor device is formed by the self‐assembly on a transparent electrode surface. The donor (see picture; dibenzotetrathienocoronene, yellow layer) deposits as supramolecular cables, and the acceptor (C60, orange) subsequently infiltrates this network. This network provides a donor–acceptor interface that is interwoven at the nanoscale. When incorporated into a solar cell, the active
realized in one step. The subtle differences in molecularstructure were confirmed by X-raycrystallography. The mechanisms for the control of different products, which involve a ring-expansion rearrangement, Scholl reactions, and/or Mallory cyclization were proposed on the basis of control experiments and DFT calculations. Such development adds good structure versatility and materials accessibility to
