A fluorescent probe for detecting pancreatic fluid containing a compound or salt thereof represented by formula (I) below.
(In the formula, A represents an amino acid residue or N-substituted amino acid residue, with A forming an amide bond with the adjacent NH in the formula; R1 represents a hydrogen atom or 1 to 4 same or different substituent groups that bond with a benzene ring; R2, R3, R4, R5, R6, and R7 each independently represent a hydrogen atom, a hydroxyl group, an alkyl group, or a halogen atom; R8 and R9 each independently represent a hydrogen atom or an alkyl group; and X represents a C1-C3 alkylene group).
A novel organoselenium fluorescent probe (Rh-Se-2), which features a high signal-to-noise ratio (up to 170-fold), fast response (5 min) and excellent immunity to interferences, was designed, synthesized and applied to bioimaging.

TiO2 nanobelts (NBs). The degradation efficiency of Rhodamine B under visible light irradiation was applied to evaluate the photocatalyticperformance of the obtained materials. Of them, TB-3 exhibited the best photocatalyticperformance, and more than 95.43% RhB was degraded under visible light. The reaction rate constant is 18.51 × 10−3 min−1, which is nine times larger than that of TiO2 NBs. Moreover
光催化技术是满足能源和环境要求的潜在技术。本文首次采用溶剂热法合成了具有0D / 1D纳米结构的Bi 2 O 2 CO 3 / TiO 2杂化物,并对得到的材料进行了系统表征。在复合材料的结构中,Bi 2 O 2 CO 3量子点(QDs)(1.40-1.50 nm)均匀地生长在TiO 2的表面上纳米带(NBs)。罗丹明B在可见光照射下的降解效率用于评估所得材料的光催化性能。其中,TB-3表现出最好的光催化性能,可见光下降解的RhB超过95.43%。反应速率常数为18.51×10 -3 min -1,是TiO 2 NBs的九倍。此外,它在回收实验中显示出显着的稳定性和可回收性。根据光电特性,优异的性能可以归因于具有0D Bi 2 O 2 CO 3 QD和1D TiO 2的异质结和杂化结构的构造。NBs使催化剂具有更快的光生载流子迁移能力和更少的电子/空穴对重组。我们的工作为构建具有0D /
