A Poly(para-phenylene) with Hydrophobic and Hydrophilic Dendrons: Prototype of an Amphiphilic Cylinder with the Potential to Segregate Lengthwise.

Langmuir monolayers are formed from an amphiphilically decorated poly(para-phenylene), which indicates that its hydrophilic and hydrophobic parts segregate lengthwise along the polymer backbone in this nanometer-sized cylinder as illustrated in A. This polymer differs from known amphiphiles in that it consists of a linear, covalently bound sequence of "little" amphiphiles. It is much more rigid than common "polysoaps", which should increase its potential to aggregate, for example, into channels.
