Two-photon pumped lasing stilbene-type chromophores containing various terminal donor groups: Relationship between lasing efficiency and intramolecular charge transfer

A series of new two-photon pumped (TPP) up-conversion lasing dyes, named as CSPI, DPASPI, PSPI, DEASPI and HEASPI respectively, have been synthesized. These dyes are stilbene-type chromophores end-capped with the same acceptor group but with varied donor

Zeolite molecular accessibility and host-guest interactions studied by adsorption of organic probes of tunable size

A series of fluorescent probe molecules based on the commercially available trans-4-(4-(diethylamino)styryl)-N-methylpyridinium iodide (DAMPI) scaffold has been developed. The dynamic radii of these DAMPI-type probes covered a range of 5.8 to 10.1 ? and c

A novel europium(iii) complex with versatility in excitation ranging from infrared to ultraviolet

One- and two-photon absorption properties of a novel europium(iii) complex containing a hemicyanine cation are investigated in this paper; in which the sensitization wavelength of europium(iii), induced by beta-diketonate ligands, is in the ultraviolet range, and the hemicyanine(aminostyrylpyridinium) cation extends the sensitization wavelength of Eu(iii) to visible region. Furthermore, under 1.06 μm ultrashort pulse laser excitation, the complex exhibits effective europium(iii) luminescence induced by the two-photon absorption of the hemicyanine cation. Therefore, this new europium(iii) complex with excitation bands in the near infrared, visible and ultraviolet ranges. Since the 1.06-μm ultrafast laser is one of the most frequently used laser sources and 1.06 μm is an 'optical window' for cells and tissues, the results suggest that this kind of complex has promising applications in deep-penetrating and high quality bioimaging in vivo. the Owner Societies 2009.
