Silole-core phenylacetylene dendrimers and their application in detecting picric acid

Silole-core phenylacetylene dendrimers were designed and synthesized, among them, the model compound (n = 0) and the first generation of the dendrimer (n = 1) were obtained by the reaction of 2,5- dibromosilole with corresponding terminal alkynes, the sec

Phenylacetylene dendrimers containing a fluorene core: Synthesis and spectroscopic studies

Phenylacetylene dendrimers 9-11 containing fluorene as the core with a larger HOMO-LUMO energy gap were synthesized and characterized. Their structure and properties were studied by UV, FL, 1H NMR, MS etc. These novel phenylacetylene dendrimers exhibit unique photophysical properties. They exist a new absorption band around 340 nm whose molar coefficient decreases with increasing generation. The band-gaps of 9-11 are 3.54, 3.43 and 3.02 respectively. The fluorescence quantum yield of 10 is as high as 0.61.

The synthesis and characterization of phenylacetylene tripodal compounds containing boroxine cores

A convergent synthesis of phenylacetylene tripodal compounds containing boroxine cores has been accomplished. The boroxine cores are assembled in high yield either by chemical dehydration or ligand-facilitated trimerization of the corresponding monomeric
