Popis: | Exciton dynamics in chiral helixes of an oligo-p-phenylenevinylene deriv. monofunctionalized with a ureido-s-triazine (MOPV) were studied. The latter functional group leads to oligomer dimerization by hydrogen bonding in dodecane soln., resulting in reversible supramol. assembly by solvophobic and p-p interactions. MOPV is a model system to study exciton transfer dynamics as it is possible to study the effect of intermol. interactions by comparing optical properties in the dissolved phase (above the transition temp.) and the supramol. assemblies. The model allows to ext. microscopic informations such as the av. exciton hopping annihilation rates. It is believed that this model also allows the quant. description of the exciton dynamics on supramol. architectures from subpicosecond to nanosecond timescales. |
