Photochemical and photophysical characteristics in the excited state properties of methoxy-substituted enediynes

Article abstract of DOI:10.1246/cl.2008.174

Effects of methoxy substituent on the phenyl ring of cis isomer of enediynes were explored. All the cis isomers exhibited fluorescence emission with moderate efficiency. Furthermore, the ortho-substituted compounds showed red shift of the fluorescence emission even though crystallographic analysis suggests that the single bond connecting the phenyl ring and carbon-carbon triple bond takes considerably twisted conformation.
