The bisthiophene and substituted benzene were used as electron\u2010donor groups at opposite sides of the pAQM electron\u2010acceptor core in asymmetric structures (\n                    <jats:bold>AsOMe<\/jats:bold>\n                    and\n                    <jats:bold>\n                      AsNMe\n                      <jats:sub>2<\/jats:sub>\n                    <\/jats:bold>\n                    ), whereas different 5\u2010phenyl thiophene moieties were symmetrically linked to the pAQM core in\n                    <jats:bold>TPh<\/jats:bold>\n                    and\n                    <jats:bold>TPhOMe<\/jats:bold>\n                    . The photoinduced excited state dynamics was investigated in a synergic effort by employing both time resolved optical and electron paramagnetic resonance (EPR) spectroscopies, with the aid of TD\u2010DFT calculations. Our femtosecond transient absorption results showed that intermolecular SF is enabled in the solid state aggregates of these compounds: the fastest and most efficient SF was revealed for the structure with the strongest push\u2013pull degree (\n                    <jats:bold>\n                      AsNMe\n                      <jats:sub>2<\/jats:sub>\n                    <\/jats:bold>\n                    ). The other asymmetric molecule (\n                    <jats:bold>AsOMe<\/jats:bold>\n                    ) interestingly exhibited higher energetic SF\u2010generated triplet excitons (1.3\u00a0eV) than literature SF\u2010materials, as demonstrated by the nanosecond transient absorption sensitization experiments, with possible intriguing implications toward silicon matched SF photovoltaics.
