Atom-transfer radical polymerization (ATRP) of acrylates from the initiator-modified zinc phthalocyanine yielded amphiphilic, phthalocyanine-terminated polymers with a narrow molecular-weight distribution. The disklike phthalocyanine moiety was incorporated into one end of the polymer chain. We investigated the aggregation behavior of phthalocyanine-terminated polymers in solution and in the solid state by using UV-visible, FT-IR, differential scanning calorimetry (DSC), and temperature-controlled powder X-ray diffraction (XRD) measurements. Amphiphilic phthalocaynine-terminated polymers that possess a poly[tri(ethylene glycol)methyl ether acrylate] chain aggregate in methanol to form a physical gel. Images from atomic force microscopy (AFM) and transmission electron microscopy (TEM) indicate that the physical gel contains a dense fibrous network structure, in which the zinc phthalocyanine groups were stacked into one-dimensional columnar aggregates through intermolecular pi-pi interactions between the pi-conjugated phthalocyanines and through van der Waals interaction of alkyl chains.
