Abstract

In this paper, we present several kinds of two-photon recordable fluorescent oligomers. It achieves high quantum yield (0.55) and high Stoke shift (100 nm). A square mark can be recorded in the fluorescent disk medium and read out by a confocal laser-scanning microscopy. The contrast of signal intensity for inside and outside of the recording mark can reach 64.6%. This fluorescent oligomer can be used for multilayer optical data storage media.
