| 제목 | Functionalized conjugated organic dyes(donor-fluorene-donor type) and their optical properties |
| 초록 | There is still a growing interest in organic dyes with large two-photon absorption (TPA) cross-section and high up conversion emission properties due to its potential for application in a wide range of areas such as frequency-up converted lasing, optical power limiting, 3-D optical data storage, 3-D lithographic micro-fabrication, and photodynamic therapy. We have synthesized functionalized conjugated organic dyes which contain an alkyl fluorene unit bridging two functionalized donor groups. In order to enhance the two photon absorption efficiency it is important to increase the electron donating ability as well as the coplanarity of the molecule. Optical power limiting was measured to investigate the two-photon absorption efficiency of these dyes. This resulting material was characterized using conventional spectroscopic methods such as FT-IR and 1H NMR, 13C NMR and Mass Spectrometer. |
