Polyphenylene dendrimers: From three-dimensional to two-dimensional structures

An elegant route to aromatic hydrocarbon dendrimers, such as 1 with pentaphenylbenzene units, and to extremely large polybenzenoid hydrocarbons is based on Diels-Alder cycloadditions of 3,4-bis-[4-(triisopropylsilylethynyl)phenyl]-2,5-diphenyl-cyclopenta-2,4-dien one and aromatic oligoethynyl compounds such as 3,3',5,5'-tetraethynylbiphenyl. The type of linkage and the high packing density of the benzene rings facilitate the cyclodehydrogenalion of appropriate dendrimeric subunits to yield planar disks.

Synthesis of carbohydrate-conjugated azaphthalocyanine complexes for PDT

Abstract A series of azaphthalocyanine (AzaPc) complexes conjugated with one or two carbohydrate groups for photodynamic therapy (PDT) were synthesized by the alkyne-azide click chemistry reaction with previously-developed AzaPc complexes incorporating th

Amphiphilic Polyphenylene Dendron Conjugates for Surface Remodeling of Adenovirus 5

Amphiphilic surface groups play an important role in many biological processes. The synthesis of amphiphilic polyphenylene dendrimer branches (dendrons), providing alternating hydrophilic and lipophilic surface groups and one reactive ethynyl group at the
