Abstract:

The exploitation of high-performance nonlinear optical (NLO) materials is necessitated by the broad application of ultra-intensive and ultra-fast lasers. The superb nonlinear absorption and electronic-structure-related NLO response of M3HHTP2 are introduced here, where M is Co(II), Ni(II), or Cu(II) and HHTP is 2,3,6,7,10,11-hexahydroxytriphenylene. With the laser excitation at 532 nm, the Cu3HHTP2 exhibits a two-photon absorption (2PA) cross-section of 1.38 +/- 0.11 x 10(7) GM, a value much larger than those of most reported NLO materials so far. The NLO response of M3HHTP2 correlates strongly with the number of metal d electrons. With metal d electrons number increasing from 7 to 10, the optical nonlinearity of M3HHTP2 under the laser excitation at 532 nm varies from three-photon absorption (3PA) in Co3HHTP2, a combination of 3PA and 2PA in Ni3HHTP2, to 2PA in Cu3HHTP2. Abundant metal d electrons can mitigate the ground-state depletion, and therefore the 2PA is enhanced. Accordingly, the superb nonlinear absorption of Cu3HHTP2 can be associated with abundant d electrons in Cu.
