Quinolines, polyquinolines, polybenzoquinolines, molecular segments of fullerenes and graphene nanoribbons, and graphene nanoribbons and processes for producing such materials are provided. The processes utilize a form of an aza-Diels-Alder (Povarov) reaction to first form quinolines and/or polyquinolines. In some such embodiments polyquinolines thus produced are used to form graphene nanoribbon precursors, and molecular segments and graphene nanoribbons. In many such embodiments the graphene nanoribbon precursors are formed from polybenzoquinolines.

Various techniques are provided to determine the presence of trace chemicals corresponding to various materials of interest. In one example, a method includes providing a chemical reporter of a chemical detector. The chemical reporter includes protonated 2-[5-methoxy-2-(4-phenyl-quinoline-2yl)-phenyl]-ethanol. A vapor-phase amine compound is subsequently received at the chemical reporter. The chemical detector then detects a response of the chemical reporter to the amine compound to determine whether materials of interest are present. Additional methods and related devices are also provided.
