Here, we report the exploration of the synergy between the concave \u03c0\u2010extended tetrathiafulvalene (exTTF) and the curved CPP scaffold for constructing the rigid, conjugated nanohoop\n                    <jats:bold>exTTF[10]CPP<\/jats:bold>\n                    . X\u2010ray analysis reveals a unique spherical packing arrangement in which six adjacent nanohoops interlock through concave and convex interactions. Interestingly, fluorescence studies revealed that\n                    <jats:bold>exTTF[10]CPP<\/jats:bold>\n                    exhibited unexpected anti\u2010Kasha emissions originating from higher excited states, along with Kasha emission from S\n                    <jats:sub>1<\/jats:sub>\n                    excited state in toluene and THF. However, in a PMMA film, it displayed a redshifted Kasha emission. The unique Kasha\/anti\u2010Kasha dual\u2010emission behavior represents a rarely explored photophysical phenomenon within exTTF derivatives and nanocarbon\u2010based systems.

Notably, femtosecond transient absorption measurements further revealed a prolonged lifetime of the charge\u2010separated state,\n                    <jats:bold>\n                      C\n                      <jats:sub>60<\/jats:sub>\n                      <jats:sup>\u2022\u2212<\/jats:sup>\n                      \/exTTF[10]CPP\n                      <jats:sup>\u2022+<\/jats:sup>\n                    <\/jats:bold>\n                    , which provides sufficient time for charge utilization.
