Non-coplanar 9,9-diphenyl-substituted oligofluorenes with large two-photon absorption enhancement.
نویسندگان
چکیده
The non-coplanar substituted phenyl rings at the 9-position of a fluorenyl unit can be involved in pi-electron delocalization in which the resulting oligofluorenes exhibit a very large enhancement of two-photon absorption cross sections up to 2559 GM at 710 nm.

متن کاملResonance enhancement of two-photon absorption in porphyrins
Two-photon absorption spectra in absolute cross-section values are presented for a number of octaethyl-, tetraphenyl-, and tetrabenzo-substituted porphyrins. In excitation spectral region of 710–810 nm, the two-photon absorption efficiency is resonantly enhanced due to nearby Q(0–0) one-photon transition. The cross-section value calculated directly from the groundand excited-state absorption pa...

The synthesis, characterization, and quantitative electronic structure modeling of multi-photon absorption properties of a neat liquid L34 (4-propyl 40-butyl diphenyl acetylene) are reported. The liquid is (linearly) transparent in the visible spectrum, but possesses large two-photon absorption (2PA) and 2PA-induced singlet and triplet excited-state absorption as measured by the Z-scan techniqu...
