Qm. Wang et Dw. Bruce, SYNTHESIS OF CALAMITIC, LIQUID-CRYSTALLINE PORPHYRINS WITH LATERAL AROMATIC BRANCHES, Tetrahedron letters, 37(42), 1996, pp. 7641-7644
The lateral, electron-accepting aromatic substituent was successfully
used to obtain a conformationally pure, laterally substituted liquid c
rystalline porphyrin. In addition, the attempt to synthesise a strappe
d, rod-like porphyrin showed that the planarity of the porphyrin core
could be crucial in molecular design to synthesize strapped liquid cry
stalline porphyrin. Copyright (C) 1996 Elsevier Science Ltd
