Two-Photon 3D Optical Data Storage via Fluorescence Modulation of an Efficient Fluorene Dye by a Photochromic Diarylethene

A two‐photon 3D optical storage system based on a photochromic diarylethene (1,2‐bis(2‐methylbenzo[b]thiophen‐3‐yl)hexafluorocyclopentene) and a highly efficient two‐photon absorbing fluorescent dye (2,7‐bis[4‐(9,9‐didecylfluoren‐2‐yl)vinyl]phenylbenzothiazole) is demonstrated. The figure shows two‐...

Description
Summary:A two‐photon 3D optical storage system based on a photochromic diarylethene (1,2‐bis(2‐methylbenzo[b]thiophen‐3‐yl)hexafluorocyclopentene) and a highly efficient two‐photon absorbing fluorescent dye (2,7‐bis[4‐(9,9‐didecylfluoren‐2‐yl)vinyl]phenylbenzothiazole) is demonstrated. The figure shows two‐photon fluorescent readout of data recorded by single‐photon excitation. The system is suitable for recording data in thick storage media and providing a non‐destructive readout method.
