Two blueish materials were obtained in the acid-catalyzed condensation of 5-pentafluorophenyldipyrromethane-1,9-bis{(petafluorophenyl)-methanol} with 4,8-dihydro-4,8-ethanopyrrol[3,4-$f$]isoindole followed by oxidation, although the yields were low. Their structures were unambiguously determined by the X-ray analysis. One was ethylene-connected bisdipyrromethene and another was bicyclo[2.2.2]octene-crosslinked dihydrohexaphyrin, which was gradually transformed to benzene-crosslinked hexaphyrin under air in solution via bicyclo[2.2.2]octadiene-crosslinked hexaphyrin. The benzene-crosslinked hexaphyrin was directly obtained in the similar acid-catalyzed condensation procedure of the dipyrromethane with 4,8-dihydropyrrol[3,4-$f$]isoindole, although the yield was also low.

5-五氟苯基二吡咯甲烷-1,9-双{(五氟苯基)-甲醇}与4,8-二氢-4,8-​​乙醇吡咯[3,4-]在酸催化下缩合得到两种蓝色物质。$F$]异吲哚，然后氧化，尽管产率较低。通过 X 射线分析明确确定了它们的结构。一种是乙烯连接的双二吡咯亚甲基，另一种是双环[2.2.2]辛烯交联的二氢六菲林，在空气中在溶液中通过双环[2.2.2]辛二烯交联的六菲林逐渐转化为苯交联的六菲林。通过类似的二吡咯甲烷与4,8-二氢吡咯[3,4-]的酸催化缩合过程直接获得苯交联的六菲啉。$F$]异吲哚，但产率也较低。
