Donor−Acceptor−Donor Fluorene Derivatives for Two-Photon Fluorescence Lysosomal Imaging
Sheng Yao,Hyo Yang Ahn,Xuhua Wang,Jie Fu,Eric W. Van Stryland,David J. Hagan,Kevin D. Belfield +6 more
TL;DR: Encapsulation of the new probes in Pluronic F 108NF micelles, and subsequent incubation in HCT 116 cells, resulted in very high lysosomal colocalization relative to commercial Lysotracker Red, making the micelle-encapsulated dyes particularly attractive as fluorescent probes for two-photon fluorescence microscopy lysOSomal imaging.
Near-infrared-emitting squaraine dyes with high 2PA cross-sections for multiphoton fluorescence imaging
TL;DR: New near-infrared emitting squaraine dyes exhibited a high two-photon absorption (2PA) cross-section (δ2PA), ∼20 000 GM at 800 nm, and high photostability with the photochemical decomposition quantum yield one order of magnitude lower than Cy 5, a commercially available pentamethine cyanine NIR dye.

Photosensitive Polymeric Materials for Two-Photon 3D WORM Optical Data Storage Systems
Ciceron O. Yanez,Carolina D. Andrade,Sheng Yao,Gheorghe Luchita,Mykhailo V. Bondar,Kevin D. Belfield +5 more
TL;DR: In this article, a fluorescence readout-based, nonlinear absorption, three-dimensional optical data storage system was proposed, where writing was achieved by acid generation upon two-photon absorption (2PA) of a photoacid generator (PAG; at 710 or 730 nm).

One- and two-photon photochemical stability of linear and branched fluorene derivatives
Claudia C. Corredor,Claudia C. Corredor,Kevin D. Belfield,Mykhailo V. Bondar,Olga V. Przhonska,Sheng Yao +5 more
TL;DR: In this article, the quantum yields of the fluorene derivatives were determined by absorption and fluorescence methods in air-saturated and deoxygenated solutions, and the values of quantum yields were in the range (1.5 −2.1) −10−6 for both types of irradiation, indicating that similar photobleaching processes occur under both one- and two-photon excitation.

Two-photon absorption cross section determination for fluorene derivatives: analysis of the methodology and elucidation of the origin of the absorption processes.
TL;DR: A comprehensive analysis of the well-known open aperture Z-scan method is presented and accounts for discrepancies in two-photon absorption cross sections between picosecond and femtosecond excitation, taking into account excited-state absorption and stimulated emission of the molecules studied.
