| 英文摘要 | A two-color two-photon laser scanning microscope (2c2pLSM) has been developed for fluorescence imaging in tissues through the nondegenerate two-photon excitation of fluorescent proteins. However, fluorescent probes have not been widely designed and applied to 2c2pLSM. Here, we have synthesized a new carbazole derivative 3,6-bis(pyridin-4-ylethynyl)-9-methyl-carbazole (BEMC), and investigated its nondegenerate two-photon absorption (ND-TPA) properties. Nondegenerate two-photon excited fluorescence (ND-TPEF) and ND-TPA cross-sections excited by a constant pump wavelength of 800 nm and several probe wavelengths from 485 nm to 650 nm were studied based on the femtosecond pump-probe technique. The fluorescence intensity is linearly dependent on each laser intensity of the two beams, and the dependence of ND-TPEF intensity on time delay between the two lasers is in good agreement with the cross-correlation of the pulse widths of the two lasers. Compared with the corresponding degenerate two-photon absorption (D-TPA) cross-sections for transition to the same excited state via the D-TPA pathway, the ND-TPA cross-sections exhibit at least twofold larger values than the D-TPA case, which is attributed to the effect of intermediate state resonance enhancement (ISRE). This study indicates that the newly synthesized carbazole derivative would serve as a promising fluorescent probe in a two-color two-photon laser scanning microscope (2c2pLSM). |
