Photophysics of π-conjugated metal­organic oligomers

Abstract
The optical absorption and photoluminescence properties of PPE-type p-conjugated oligomers that contain a 2,2-bipyridine-5,5¢-diyl metal coordinating unit have been examined. The spectra of the free oligomers are compared with those that contain ­Re(CO)3Cl and ­Ru(bpy)22+ chromophores chelated to the bpy-diyl unit.
