A new carbazole-containing naphthodithiophene heteroaromatic compound, 5,6-bis[9-(2-decyltetradecyl)-9H-carbazol-3-yl]naphtho[2,1-b:3,4-b’]dithiophene (M1), was synthesized to be subsequently used as the weak donor structure for the construction of narrow bandgap D–A conjugated polymers in terms of the “weak donor–strong acceptor” concept. The composition and structure of M1 were confirmed by the data of elemental analysis and IR and 1H and 13C NMR spectroscopy. The optical and electrochemical characteristics of the product were measured. The compound M1 was shown to have low-lying HOMO (–5.57 eV), which is favorable for high open-circuit voltage and to be suitable as a promising weak donor moiety in the D–A conjugated polymer for photovoltaic applications.

A new carbazole-containing naphthodithiophene derivative—heteroaromatic compound 5,6- bis[9-(2-decyltetradecyl)-9H-carbazol-3-yl]naphtho[2,1-b:3,4-b']dithiophene (M1)—has been synthesized. The compound will be used by us as a weak donor structural block for fabricating narrow-bandgap D–A conjugated polymers. The composition and structure of M1 have been confirmed by elemental analysis data, IR spectroscopy, and 1H and 13C NMR. The synthesized compound has a low HOMO energy (–5.4 eV), which is favorable for a high open-circuit voltage. Monomer M1 can be used as a promising weak donor moiety in D–A conjugated polymers for solar photovoltaics.

The synthesis and scanning tunneling microscopy (STM) investigations of shape-persistent arylene-ethynylene-butadiynylene macrocycles along with their codeposites with metallacycles are reported. 2D ordered arrays of macrocycles and macrocycle/metallacycle architectures (1:1) have been obtained on HOPG by self-assembly under ambient conditions. It is found that the ordered macrocycle array acts as a template for the deposition of the adlayer molecules. For each underlying macrocycle, one metallacycle has been detected. The unit-cell data of both, the macrocycles and their codeposites, show that the structural information of the macrocycle layer is perfectly transformed to the guest molecules. A rather unexpected observation is that the present compound could not be coadsorbed with C60, indicating that only a minor change in the structure of the macrocycle has a dramatic effect on the ability of the monolayer to bind additional guest molecules.

(Chemical Equation Presented) We report the design and synthesis of annulated thiepins designed to undergo bent-to-planar transformation driven by aromatization under electrochemical control. Thiepins are conjugated seven-membered ring systems with a thioether in the macrocycle. We synthesized thermally stable thiepins that are electropolymerizable to give rise to thiepin-containing electroactive polymers. Extended thiepin systems undergo sulfur extrusion with oxidation, and this feature has utility in peroxide sensing. 2009 American Chemical Society.
