1Hybrids of gold nanoparticles and oligo(p-phenyleneethynylene)s end-functionalized with alkynylruthenium groups:Outstanding two-photon absorption in the second biological window显示文摘Oligo(p-phenyleneethynylene)s(OPEs)end-capped with(alkynyl)bis(diphosphine)ruthenium and thiol/thiolate groups stabilize ca.2 nm diameter gold nanoparticles(AuNPs).The morphology,elemental composition and stability of the resultant organometallic OPE/AuNP hybrid materials have been defined using a combination of molecular-and nano-material chacterization techniques.The hybrids display long-term stability in solution(more than a month),good solubility in organic solvents,reversible rutheniumcentered oxidation,and transparency beyond 800 nm,and possess very strong nonlinear absorption activity at the first biological window,and unprecedented two-photon absorption activity in the second biological window(σ2 up to 38,000 GM at 1,050 nm).Cristóbal Quintana Mahbod Morshedi Jun Du Joseph P.L.Morrall Jan K.Zaręba Marek Samoc Marie P.Cifuentes Mark G.Humphrey 2020Nano Research2020,13,10:1
