title = "Self-assembly of chiral star-shaped oligo(p-phenylene vinylene) substituted hexaarylbenzenes",
abstract = "Self-assembly is a promising approach for the construction of nano-sized objects with a specific function. Recently, we have reported on a star-shaped oligo(p-phenylene vinylene) (OPV) substituted hexaarylbenzene in which the no. of OPV segments is increased to six, and the propeller-like structure resulted in more stable stacks in alkane solvents. The stability of the assemblies enabled the use of size exclusion chromatog. (SEC) to study the monomer content in addn. to the normally applied temp. and concn. dependent optical techniques, which mainly probe the assembly characteristics. The formation of two types of assemblies, as visualized with CD spectroscopy, allowed for the visualization of a bimodal distribution in the SEC trace where the two peaks could be assigned to monomers and assemblies by UV/vis spectroscopy. The application of SEC showed for the first time the analogy of the cooperative nucleation-elongation self-assembly mechanism with chain-growth polymn. in covalent polymer chem.",
