Abstract
A number of novel amphiphilic phthalocyanines (Pcs) have been prepared containing long alkyl (-C16H33) and oligo(ethyleneoxy) chains (-O(C2H 4O)(3)CH3) in the peripheral positions. All the Pcs prepared showed li quid crystalline behaviour, with most compounds giving two mesophases. Optical microscopy suggests that the lower temperature mesophase (M1) is a discotic rectangular mesophase, and that the higher temperature mesophase (M2) is a discotic hexagonal phase.
