Palladium nanoparticle-incorporated metal-organic framework MIL-101 (Pd/MIL-101) was successfully synthesized and characterized using X-ray diffraction, nitrogen physisorption, X-ray photoelectron, UV-visible and infrared spectroscopies, and transmission electron microscopy. The characterization techniques confirmed high porosity and high surface area of MIL-101 and high stability of nano-size palladium particles. Pd/MIL-101 nanocomposite was investigated for the Sonogashira cross-coupling reaction of aryl and heteroaryl bromides with various alkynes under copper-free conditions. The reusability of the catalyst was tested for up to four cycles without any significant loss in catalytic activity.

In furtherance of our research on the design, synthesis and study of electrogenerated chemiluminescence (ECL) of new donor substituted phenylquinolinylethynes, we report here more new series with the aim of studying the effect of positional isomerism on their overall photophysical properties with a special focus on ECL. For this study we have chosen 2-, 3-, and 4-(p-substituted phenyl)ethynylquinolines, and 1- and 4-(p-substituted phenyl)ethynylisoquinolines. These ethynes were synthesized in good yields by modified Sonogashira coupling of the corresponding terminal alkyne with the respective haloquinolines. The photophysical properties and ECL were studied in acetonitrile solvent and the various results are discussed.
