is prepared DEAS-bpy
=
4,4â²-bis[p-(diethylamino)-α-styryl]-2,2â²-bipyr
idine, BPP = 1,10-bis(4-pyridyl)-3,8-dimethyl-1,3,5,7,9-decapentaene}
in which electrochemical and photophysical properties clearly indicate the
presence of a long-lived charge-separated excited state at room
temperature upon light excitation.
