✦ Synopsis

We report the observation of fhrorescexe from higher singIet levels of biphenyIene. The moIecuIe was excited by either txo-or three-photon absorption and the resulting fluorescence to the ground state was observed in a broad band centered near 265 nm_ We have measured the decay time of the lowest exited singlet state to be 240 f 20 ps in he.xane at 300 I(.

The photophysical behavior of biphenylene has been investigated employing picosecond time-resolved absorption measurements over the range 400-760 nm. The temporal behavior of the different absorption maxima suggest that the transient absorption results from two different configurations of biphenylen
