- W1967359265 abstract "Bis-(diphenylamino)diphenylpolyenes have been shown to form exceptionally stable, highly absorbing bipolaronic dications in solution and thin film. Replacement of one diphenylamino substituent with a N-(hydroxyethyl), N-ethylaminophenyl moiety yields a polyene series that also form stable bipolarons, and are intensely fluorescent. These new chromophores are also easily attached to either a PMMA backbone or to 3,5-dihydroxybenzyl alcohol to yield functionalized dendrons capable of attachment to various core molecules to yield functionalized dendrimers. Diphenylamino-substituted PPV oligomers can also be obtained with similar functionality. These new materials all possess large two-photon cross-sections and display optical limiting for nanosecond pulses with peak activity extending into the visible portion of the spectrum. In this presentation we will discuss the synthesis of these new materials and preliminary characterization as two-photon absorbers, photoluminescent materials suitable for organic light- emitting diodes, and as dendrimers capable of 3D charge delocalization and exceptionally large third order hyperpolarizabilities." @default.
