Functionalized cyano-OPVs as melt-processable two-photon absorbersElectronic supplementary information (ESI) available: Crystallographic data and procedures for the structural analysis of A3; differential scanning calorimetry traces; absorbance and fluorescence spectra. See DOI: 10.1039/c2jm15846a
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 400850 GM, can be melt-proc...
