Abstract

Several cyano-functionalized oligo(phenylenevinylene) (cyano-OPV) dyes were modified with different alkyl substituents with the objective to develop melt-processable, two-photon absorbing materials. The new dyes exhibit two-photon absorption cross-sections in the range of 400–850 GM, can be melt-processed at temperatures as low as ∼100 °C, and offer high thermal stability. The propensity of these molecules to form excimers also makes them interesting for sensor and data storage applications.
