Synthesis of rigid-rod linkers to anchor chromophores to semiconductor nanoparticles was written by Wang, Dong;Schlegel, James M.;Galoppini, Elena. And the article was included in Tetrahedron in 2002.SDS of cas: 313648-56-5 This article mentions the following:
Four rigid-rod sensitizers, made of a phenylethynyl spacer substituted with a chromophore and two COOR binding groups, were prepared to study dynamics of electron injection at the interface of metal oxide semiconductor nanoparticles. Di-Me Ru(bpy)2((5-(5-1,10-phenanthrolinyl)ethynyl)isophthalate)2+, di-Me Ru(bpy)2(5-(4-(2,2′-bipyridinyl)ethynyl)isophthalate)2+, di-Me 5-(1-pyrenylethynyl)isophthalate, and di-Me 5-(9-anthracenylethynyl)isophthalate were synthesized and characterized. Their absorption spectra, emission spectra, and electrochem. properties have been studied in acetonitrile and hexane solutions at room temperature In the experiment, the researchers used many compounds, for example, Dimethyl 5-ethynylisophthalate (cas: 313648-56-5SDS of cas: 313648-56-5).
Dimethyl 5-ethynylisophthalate (cas: 313648-56-5) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.SDS of cas: 313648-56-5
