Abstract

Aliphatic derivatives of hydrazinophyrin, a new type of tetrapyrrolic macrocycle prepared by the condensation of 2,5-diformylpyrroles with hydrazine, exhibit liquid crystalline properties as judged from polarising optical microscopy; these hydrazinophyrins appear to be the first mesogens derived from an expanded porphyrin core.

Metallomesogens with Luminescent Behaviour: Palladium Complexes Derived from Alkylamide Tetraarylporphyrins

“…[20,21] The most significant LC behaviour was found by peripheral modification of octa-substituted and meso-tetraphenylporphyrinic derivatives. [2,[20][21][22][23][24][25][26][27][28] Additionally,s ome tetrapyrrolic macrocyclesp eripherally substituted have LCs properties and exhibit columnar mesophases. [29,30] Following our research interests in discotic LC and luminescent materials, [31][32][33] and considering the potential of functionalised meso-tetraarylporphyrins in this field, [34] we decided to prepareaseries of easily accessible porphyrins containing four (3a,b)o re ight (3c,d)a liphatic amide chains with different lengths.…”
