Herein, we report the IR spectrum of isolated c-C6H_5~+ obtained by Ar-tagging IR photodissociation (IRPD). This IRPD approach was previously used to elucidate the structure of related fundamental hydrocarbon ions, e.g., C6H_7~+, C2H_5~+ and C,H_3~+.Alexander Patzer...
The spectral stability is outstanding: no recognizable change is observed in the electroluminescence spectrum even when the device current is raised. Novel fluorene-containing polymers, poly[1-pentyl-2-(9,9-dimethylfluoren-2-yl)acetylene] (35 in Figure 14) and poly[1-(3,4-difluorophenyl)-2-(...

However, the 1H NMR spectrum in CDCl3 showed the coexistence of the keto and enol tautomers. When the spectrum was recorded immediately after dissolution, 100% of the keto-tautomer was present. However, after 2–3 weeks the ratio of the enol tautomer increased to 30%. This series o...
The ECD spectrum of the simplified model compound a, the deacetyl analog of 1, was calculated at the B3LYP/6-31+G(d) level. The experimental ECD spectra of 1 and 2 were in strong agreement with the calculated model compound a (Figure 3). Thus, the absolute configuration of 1 was ...
PMR spectrum exhibited proton signals due to one 1,2,4-trisubstituted benzene ring (6.98, br. d, 8.4, H-6; 7.08, br. s, H-2; 7.14, d, 8.4, H-5), one 1,2,3,5-tetrasubstituted benzene ring (6.85, br. s, H-2′; 7.01, br. s, H-6′), a double bond with a trans ...
