Construction of phthalocyanine‐terminated polystyrene nanoarchitectures

Abstract

Nanostructuring of phthalocyanine‐based materials is a powerful tool towards the preparation of new materials with outstanding properties. It has been previously shown that porphyrin‐functionalized and phthalocyanine‐functionalized polymers give rise to nanosized aggregates. With the goal in mind of searching new phthalocyanine‐containing polymeric materials that are able to self‐organize into stable supramolecular nanostructures, we have prepared unsymmetrically functionalized Zn(II) phthalocyanines that are able to behave as initiators in the atom transfer radical polymerization of styrene. Hybrid phthalocyanine–polystyrene materials of different tail lengths have been prepared, and their self‐organization behavior was studied by means of UV–Vis spectroscopy and transmission electron microscopy.

Octa-armed star-shaped poly(ε-caprolactone)s with a phthalocyanine core by ring-opening polymerization: Synthesis and characterization

“…Polymers bearing phthalocyanines can be classified on the basis of the incorporation type of the macromolecule as a side chain, network, or main chain [38]. Few examples of polymers containing a terminal phthalocyanines core have been studied [39][40][41][42][43][44].…”

Investigation of electrochemical properties and gas adsorption studies of novel sandwich core phthalocyanines

“…Phthalocyanines (Pcs) have been attracted great attention of scientists due to their unique physicochemical and electrochemical properties and usability in number of applications including photodynamic therapy (PDT), Langmuir‐Blodgett films, organic light‐emitting diodes (OLED), catalysts, solar cells, and nonlinear optics . Electrochemical characterizations of metal phthalocyanines (MPcs) are related to the extensive π‐electron delocalization of the Pc rings, redox activity of the central metals, and functionality of the substituent environments of the ring .…”

“…In addition, the concentration and distribution of the organic functional cores could be controlled by covalently linked arm polymers. In this study, we developed a facile synthetic route to a Pc‐cored star polymer using a combination of atom transfer radical polymerization (ATRP) and a Pc cyclization reaction . The cyclization reaction of Pc with a variety of metal ions generally gave high yields without tedious purification procedures.…”

“…In this study, we developed a facile synthetic route to a Pc-cored star polymer using a combination of atom transfer radical polymerization (ATRP) [ 36 ] and a Pc cyclization reaction. [37][38][39] The cyclization reaction of Pc with a variety of metal ions generally gave high yields without tedious purifi cation procedures. Furthermore, by utilizing ATRP, various arm polymers could be readily synthesized with controlled molecular weights and narrow polydispersity, eventually yielding well-defi ned Pc-cored star polymers with precisely known arm numbers and arm lengths.…”
