  aromatics such as nitrobenzene or nitronaphthalenes and give the corresponding pyrroles in good yields. Pyrroles prepared by this method have been converted into porphyrins fused with various aromatic rings by the reduction with LiAlH4 followed by treatment with an acid catalyst and oxidation with chloranil or oxygen. Tetra-1,2-naphthoporphyrin has been prepared by the reaction of 2-nitro-3,4-dihydronaphthalene

  通过在DBU存在下使芳族硝基化合物与异氰基乙酸乙酯反应，可以容易地制备与芳环稠合的吡咯。该反应的容易程度取决于起始硝基芳族化合物的芳族性。多环芳族硝基化合物（例如1-硝基or或9-硝基菲）比简单的硝基芳族化合物（例如硝基苯或硝基萘）具有更高的反应性，并能以高收率得到相应的吡咯。通过LiAlH 4还原，已将通过该方法制备的吡咯转化为与各种芳环稠合的卟啉然后用酸催化剂处理，并用氯乙腈或氧气氧化。通过使2-硝基-3,4-二氢萘或1-硝基萘与异氰基乙酸乙酯反应，然后还原，四聚和氧化反应，可制得1，4-萘卟啉。因此，容易从芳族硝基化合物开始制备高度共轭的卟啉，并且可以通过选择起始芳族硝基化合物来控制它们的电子和光学性质。

  Acenaphthoporphyrins, a new group of porphyrins with strongly red shifted electronic absorption spectra, have been prepared by the acid catalysed condensation of a pyrrole-2,5-dicarboxaldehyde with acenaphthotripyrranes; similarly, c-annelated pyrroledialdehydes afforded the related opp-diacenaphthoporphyrins and a mixed porphyrin system with fused phenanthrene and acenaphthylene rings.

  Incorporation of acenaphtho[1,2-c]pyrrole units into the pi-conjugated systems is very effective to get the narrow HOMO-LUMO gap materials, and the absorption spectra of pi-conjugated polymers, porphyrins, and boron dipyrromethene dyes fused with acenaphthene rings are extensively red-shifted.

  As part of a survey on the influence of fused aromatic rings on the porphyrin chromophore, a series of novel structures with fused acenaphthylene or benzothiadiazole rings have been synthesized. Base-catalyzed condensation of 1-nitroacenaphthylene or 4-nitrobenzothiadiazole with esters of isocyanoacetic acid afforded good yields of the annelated pyrroles 5 and 28. Cleavage of the ester moieties with KOH in refluxing ethylene glycol gave the unsubstituted heterocycles, and subsequent condensation with 2 equiv of acetoxymethylpyrroles 9 in acetic acid/ethanol produced the modified tripyrranes 12 and 31. Tripyrranes with terminal tert-butyl ester units were treated with TFA and condensed with 3,4-diethyl-2,5-pyrroledicarboxaldehyde 13 in dichloromethane to give, following oxidation with DDQ, the corresponding pi-extended porphyrins 14 and 32. Acenaphthoporphyrins 14 showed unique UV-vis spectra with a triply split Soret band region and a relatively strong band near 660 nm. Strongly red-shifted absorptions were also noted for the dications and the nickel(II), copper(II), and zinc chelates for this system. Thiadiazoloporphyrins 32 gave two broadened Soret bands, but the Q-band region was unexceptional. However, the nickel(II), copper(II), and zinc complexes all showed abnormally strong absorptions between 600 and 612 nm. Porphyrins with two antipodal fused aromatic rings were easily prepared by condensing c-annelated pyrroledialdehydes 17 with tripyrranes 12 and 31, and the spectroscopic properties of the resulting porphyrins showed that the observed ring-fusion effects were essentially additive. Porphyrins with two adjacent acenaphthylene rings were also prepared by the MacDonald "2 + 2" condensation, although this chemistrry gave poor results in the synthesis of a porphyrin with two fused benzothiadiazole rings. The spectroscopic properties of these new highly conjugated porphyrin structures show that ring fusion can profoundly modify the porphyrin chromophore.
