Yet, the origin of these properties is still not entirely understood. Here, we describe a unified picture of the lowest electronic excited states in Y6 films and contrast them with those prevalent in ITIC and C\n                    <jats:sub>60<\/jats:sub>\n                    films. Y6 supports hybrid local\u2010exciton (LE)\u2013charge\u2010transfer (CT) states stabilized via intermolecular electronic couplings and short\n                    <jats:italic>\u03c0\u2013\u03c0<\/jats:italic>\n                    contacts, which result in excimer\u2010like states delocalized over aggregates. The large change in dipole moment for the S\n                    <jats:sub>0<\/jats:sub>\n                    \u2192S\n                    <jats:sub>1<\/jats:sub>\n                    transition makes this excitation sensitive to the polarizable environment, with dielectric stabilization red\u2010shifting S\n                    <jats:sub>1<\/jats:sub>\n                    and bringing LE and CT configurations into near resonance. This polarization\u2010driven LE\u2013CT hybridization contrasts with the situation in ITIC and C\n                    <jats:sub>60<\/jats:sub>\n                    , where S\n                    <jats:sub>1<\/jats:sub>\n                    remains LE (Frenkel)\u2010like and CT states lie energetically higher. Also, reports of intrinsic free\u2010charge photogeneration in neat Y6 and C\n                    <jats:sub>60<\/jats:sub>\n                    films are discussed; devices are found to deliver efficiencies &lt;1% unless aided by transport layers or donor additives.
