New 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) derivatives (1 and 2) were synthesized as an "off-on" fluorescent chemosensor and fluorescent chemodosimeter for Cu2+ and Pb2+. Compound 1 displayed selective and large chelation enhanced fluorescence effects with Pb2+ and Cu2+ among the metal ions examined. On the other hand, compound 2, a fluorescent chemodosimeter, effectively recognized Cu 2+ via a selective hydrolysis of the acetyl group.

The invention belongs to the technical field of fine chemicals, in particular to double-cyano stilbene ethylene two-photon fluorescent solvent chromophore water-soluble probe and its synthetic method and application, the probe in order to double-cyano stilbene (DCS) for the two-photon fluorescent matrix preparation. The probe molecules of small size, good solubility in water and is suitable for solvent polarity detection, in addition to the fluorescence intensity of the probe, two-photon absorption cross section of the insured with viscosity changes obviously, display a very wide range of solvent chromophore, large two-photon absorption cross section and ultra-large Stokes displacement, thereby greatly improving the detection sensitivity, imaging resolution, sensitivity and transverse and longitudinal resolution, and the accuracy of the test; cell microscopic imaging experiment to demonstrate that its in a cell or tissue has good color range and absorption effect, can be very good detection and reflect cell change in viscosity of the situation, and itself not toxic to the cells. In biological, in the medical field has great application value. (by machine translation)

Using an environmentally stable metal as the cathode in a polymer light-emitting diode (PLED) is an essential requirement for its practical application. We present the preparation of a water/alcohol soluble copoly(p-phenylene) (P1) containing pendant azacrown ether and ethylene glycol ether groups as a highly efficient electron injection layer (EIL) for PLEDs, allowing the use of environmentally stable aluminum as the cathode. Multilayer PLEDs [ITO/PEDOT:PSS/PF-Green-B/EIL/Al] using P1 as EIL exhibit significantly enhanced device performance, particularly in the presence of K 2CO3 or Cs2CO3. The maximum luminous power efficiency and maximum luminance of the device with Cs2CO 3-doped P1 as EIL were enhanced to 9.16 lm W-1 and 17050 cd m-2, respectively, compared with those without EIL (0.16 lm W -1, 890 cd m-2). The turn-on voltage was also significantly reduced from 5.7 V to 3.7 V simultaneously. The performance enhancement has been attributed to improved electron injection which has been confirmed by the rise in open-circuit voltage (Voc) obtained from photovoltaic measurements. The incorporation of such an electron injection layer significantly enhances device performance for PLEDs with an environmentally stable metal as the cathode.
