science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2010 Substance: diphenylene Other Names: biphenylene Formula: C12H8 CAS-No.: 259-79-0 Study: uv spectrum Authors: C. Dosche, H.-G. Löhmannsröben, A. Bieser, P. I. Dosa, S. Han, M. Iwamoto, A. Schleifenbaum, K. P. C. Vollhardt Title: Photophysical properties of [N]phenylenes Journal/Source: Phys. Chem. Chem. Phys., 4, 2156, (2002); DOI: 10.1039/b109342h Data: (diagram, table, disk): diagram Energy/Wavelength range: 240 - 440 nm Resolution: Temperature: 298 K Temperature dependence: Pressure/Concentration Comments: In the present study, photophysical properties of [N]phenylenes were studied by means of stationary and time-resolved absorption and fluorescence spectroscopy (in THF at room temperature). The extinction coefficient of the first singlet absorption feature at lambda(max) = 392 nm is epsilon = (0.12 ± 0.01) x 10^3 M-1 cm-1.
