Five novel long-chain-substituted porphyrin derivatives, tetrakis(3,4-dialkylphenyl)porphyrins (abbreviated as (C n ) 8 TPPH 2 (n = 8, 12, 18), (C 18 ) 8 TPPCu and (C 18 ) 8 TPPNi), were synthesized and their mesomorphism was investigated. It was found that the (C n ) 8 TPPH 2 (n = 8, 12), derivativ
