Marius A. Albota,David Beljonne,Jean-Luc Brédas,J. E. Ehrlich,Jia Ying Fu,Ahmed A. Heikal,Samuel E. Hess,Thierry Kogej,Michael D. Levin,Seth R. Marder,D. McCord-Maughon,Joseph W. Perry,H. Rockel,Mariacristina Rumi,Girija Subramaniam,Watt W. Webb,Xiang Li Wu,Chris Xu +17 more
TL;DR: The combination of large delta and high fluorescence quantum yield or triplet yield exhibited by molecules developed here offers potential for unprecedented brightness in two-photon fluorescent imaging or enhanced photosensitivity in two -photon sensitization, respectively.
Journal ArticleDOI
Two-photon polymerization initiators for three-dimensional optical data storage and microfabrication
Brian H. Cumpston,S. Ananthavel,Stephen Barlow,Daniel L. Dyer,J. E. Ehrlich,L. Erskine,Ahmed A. Heikal,Stephen M. Kuebler,I.-Y. Sandy Lee,D. McCord-Maughon,Jinqui Qin,Jinqui Qin,H. Rockel,Mariacristina Rumi,Xiang Li Wu,Seth R. Marder,Seth R. Marder,Joseph W. Perry,Joseph W. Perry +18 more
TL;DR: In this article, a class of π;-conjugated compounds that exhibit large δ (as high as 1, 250 × 10−50 cm4 s per photon) and enhanced two-photon sensitivity relative to ultraviolet initiators were developed and used to demonstrate a scheme for three-dimensional data storage which permits fluorescent and refractive readout, and the fabrication of threedimensional micro-optical and micromechanical structures, including photonic bandgap-type structures.

TL;DR: The two-photon absorption properties of a series of bis dialkylamino or diarylamino-substituted diphenylpolyenes and bis(styryl)benzenes have been investigated in this article.
Journal ArticleDOI
Two-photon absorption and broadband optical limiting with bis-donor stilbenes.
TL;DR: Large two-photon absorptivities are reported for symmetrical bis-donor stilbene derivatives with dialkylamino or diphenylamino groups, offering an unprecedented combination of broad optical limiting bandwidth and high linear transparency.
