Two novel terpyridine-based chromophores with donor-acceptor structural model containing modified triphenylamine moiety： Synthesis, crystal structures and two-photon absorption properties

Two novel terpyridine-based chromophores with D-A （D = donor, A = acceptor） structural model containing modified triphenylamine moiety （L1 and L2 ） have been conveniently synthesized via formylation and reduction in satisfactory yields, and fully characterized. The single crystals of them were obtai...

Description
Summary:Two novel terpyridine-based chromophores with D-A （D = donor, A = acceptor） structural model containing modified triphenylamine moiety （L1 and L2 ） have been conveniently synthesized via formylation and reduction in satisfactory yields, and fully characterized. The single crystals of them were obtained and determined by X-ray diffraction analysis. The relationships between structure and photophysical properties of the two chromophores were investigated both experimentally and theoretically. The measured maximum TPA cross-sections per molecular weight （δmax /MW） of the chromophores are 0.63 GM/（g mol） （L1） and 0.72 GM/（g mol） （L2）, respectively, in DMF as a high polar solvent. The results indicate that the value of δmax/MW could be well tuned by the intramolecular charge transfer （ICT）, which could be realized by introducing additional elecron-donor/acceptor groups.
