✦ Synopsis

A new and efficient method of preparing 3,4-pyrrolediacetic diffraction, and miscibility tests. The planarity of the macrocyclic core constitutes the major structural requirement esters 3 is reported, together with their conversion, according to the Lindsey procedure, to a series of octa-and dodeca-for mesophase formation. The mesophase temperature range is controlled by the length of the side chains through the substituted porphyrins. This procedure, which consists of a palladium-catalysed oxidative alkoxycarbonylation of N-melting point and by the strength of π-π interactions among the cores through the clearing point. The same set of rules substituted dipropargylamine derivatives 1, works nicely for n-alkyl alcohols in the range C 1 to C 14 . The thermotropic governing porphyrin packing in the solid state can be employed to predict mesophase formation and organization behaviour of this series of porphyrins (28 compounds) has been investigated using polarization microscopy, DSC, X-ray in porphyrin octaesters
