Naphthobipyrrole is a potentially useful building block for porphyrin and porphyrin analogue synthesis. Reported here is a simple, generalizable synthetic route to α-formylated, β-substituted naphthobipyrroles and their use in the preparation of binaphthoporphycenes. The resulting binaphthoporphycenes possess a planar geometry as determined via a single-crystal X-ray diffraction analysis; they also
Naphthobipyrrole 是卟啉和卟啉类似物合成的潜在有用构件。这里报道了一种简单、可推广的 α-甲酰化、β-取代萘并联吡咯的合成路线及其在制备双萘并卟啉中的用途。通过单晶 X 射线衍射分析确定,所得的双萘卟啉具有平面几何形状;与简单的卟啉相比,它们还显示出吸收最大值发生红移。

Two novel electron accepting bis-isatins, having fused bis-lactam rings have been synthesized from corresponding pyrroloindoles 7 and 14 by one-pot direct oxidation approach involving oxidant NBS with or without co-oxidant TBHP in DMF/CHCl3. Synthesized fused bis-isatins 8 and 15 are extensively studied for thermal, photophysical, electrochemical and thin-film morphological properties and are found to have characteristic properties like solid-solid transitions, visible light absorption, lowered FMO energy levels (LUMOs below -4.1 eV and HOMOs below -5.9 eV) as well as oriented packing of molecules in the film state. The famous indophenine reaction is re-visited with fused bis-isatins to form conjugated polymers P-1 and P-2, having quinoidal pyrroloindole dione units. The polymers are studied for thermal, photophysical, electrochemical and thin-film morphological properties indicating sufficiently high thermal stability (up to 200 degrees C), extended absorptions up to near IR region, lowered FMO energy levels (LUMOs below -4.3 eV and HOMOs below -5.8 eV) and amorphous nature of polymer films.
