Single-material organic solar cells (SMOSCs) promise several advantages with respect to prospective applications in printed large-area solar foils. Only one photoactive material has to be processed and the impressive thermal and photochem. long-term stability of the devices is achieved. Herein, a novel structural design of oligomeric donor-acceptor (D-A) dyads 1-3 is established, in which an oligothiophene donor and fullerene acceptor are covalently linked by a flexible spacer of variable length. Favorable optoelectronic, charge transport, and self-organization properties of the D-A dyads are the basis for reaching power conversion efficiencies up to 4.26% in SMOSCs. The dependence of photovoltaic and charge transport parameters in these ambipolar semiconductors on the specific mol. structure is investigated before and after post-treatment by solvent vapor annealing. The inner nanomorphol. of the photoactive films of the dyads is analyzed with transmission electron microscopy (TEM) and grazing-incidence wide-angle X-ray scattering (GIWAXS). Combined theor. calculations result in a lamellar supramol. order of the dyads with a D-A phase separation smaller than 2 nm. The mol. design and the precise distance between donor and acceptor moieties ensure the fundamental phys. processes operative in organic solar cells and provide stabilization of D-A interfaces. The experimental part of the paper was very detailed, including the reaction process of 6-Aminohexan-1-ol(cas: 4048-33-3Application of 4048-33-3)
6-Aminohexan-1-ol(cas: 4048-33-3) may be used along with glutaric acid to generate poly(ester amide)s with excellent film- and fiber forming properties. It can undergo cyclization over copper supported on γ-alumina and magnesia to form hexahydro-1H-azepine.Application of 4048-33-3
