Abstract

Ten novel long-chain-substituted porphyrin derivatives, tetrakis( 3,4-dialkoxyphenyl) porphyrins [abbreviated as (CnO)(8)TPPM: M = H-2, n = 4, 6, 8, 10, 12, 16, 18; M = Cu, n = 8, 12 and (2EtC(6)O)(8)TPPH2], were synthesizedand their mesomorphism was investigated. Among them four derivatives, (CnO)(8)TPPH2 (n = 12, 16, 18) and (C12O)(8)TPPCu, exhibited a monotropic discotic lamellar (D-L) mesophase.
