“…The synthesis of complex hybrid nanostructures is crucial for fabricating high-performance nanodevices in the future. 1 The main challenges lie in controlling of the alignment of component nanoparticles and fundamentally understanding the correlation between morphology and performance of complex nanostructures. In the past a few decades, the synthesis of complex nanostructures based on carbon nanotubes and DNA has been extensively investigated.…”

Functionalized cyano-OPVs as melt-processable two-photon absorbers

“…13 The integration of additional electron-accepting groups in the conjugated system, so that D-p-A-p-D structures are created, further increases s. 12 Maximization of s, however, often comes at the expense of processability, since extended p-systems usually exhibit high melting and dissolution enthalpies and low melting and dissolution entropies, leading to limited solubility and high melting temperatures. Nevertheless, for many devices, such as optical switches, multiplexers based on macroporous silicon structures that are locally infiltrated with a neat NLO dye, 14 or multilayered adaptive dielectric mirrors, 15 it would be desirable if the NLO material could be melt-processed at low temperatures and/or processed from high-concentration solutions. We here report the investigation of several cyano-substituted oligo(phenylenevinylene)s (cyano-OPVs, Fig.…”

A melt-processable squaraine-based organic glass for nonlinear optics

“…These features and its appreciable s of $1490 GM at a resonance wavelength of 1160 nm, suitable for operation at telecommunication wavelengths, suggest that 3 could be an attractive candidate for devices that require integration of a (nonfluorescent) nonlinear optical solid in complex shapes, such as Siorganic-hybrid waveguides. 6…”
