A new carbazole-related small mol. exhibiting self-assembly into ordered nanostructures in solution-processed cast films has been synthesized and its charge-photogeneration and -transport properties have been investigated. Large photoconductivity was measured in the amorphous state while an enormous improvement in the photoconduction properties was observed when the mols. spontaneously organized. Photocurrents increased upon self-assembly by up to four orders of magnitude, mostly due to the drastic enhancement of the charge photogeneration. A greatly favorable arrangement of the aromatic cores in the resulting nanostructures, which were characterized by X-ray anal., may explain these improvements. Photocurrents of mA cm-2, on/off ratios of 104 and quantum efficiencies of unity at low field and light intensity, which are among the best values reported to date, along with the simplicity of fabrication, give this readily-available organic system great potential for use in plastic optoelectronic devices. In the experiment, the researchers used many compounds, for example, 10,15-Dihydro-5H-diindolo[3,2-a:3′,2′-c]carbazole (cas: 109005-10-9Electric Literature of C24H15N3).
10,15-Dihydro-5H-diindolo[3,2-a:3′,2′-c]carbazole (cas: 109005-10-9) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Electric Literature of C24H15N3
