Coassembly-Directed Fabrication of an Exfoliated Form of Alternating Multilayers Composed of a Self-assembled Organoplatinum(II) Complex–Fullerene Dyad

The
self-assembly of covalently linked dyad 1a of cyclometalated
organoplatinum­(II) complex and fullerene afforded alternating multilayers
of electron-rich and -deficient molecular components. On the other
hand, the coassembly of 1a with organoplatinum­(II) complex 2 having no fullerene moiety gave an exfoliated form of the
multilayers, by inhibiting the interdigitation of organoplatinum­(II)
complex moieties of 1a. The coassembled 1a/2 transports both of the photogenerated holes and electrons,
while the self-assembled 1a allows only the transportation
of electrons under the same conditions.
