Περίληψη:	The supramolecular association of an oligophenylene-vinylene (OPV)-based Hamilton-type receptor 1 with C60-barbiturate 2, via six hydrogen bonds per OPV terminal, forming C60/OPV/C60 complex 3 is presented. The particular host-guest motif expressed in 3 ensures strong interactions between the discrete components of the complex based on the multiple hydrogen bonding interactions as conveyed by an association constant greater than 105 M-1. Furthermore, femto- and nano-second transient absorption studies disclose photoinduced charge separation from 1OPV∗ to C60 within 9.4 ps. The observed ultrafast charge separation phenomena in the C60/OPV/C60 complex open up wide avenues toward the efficient construction of new materials for optoelectronic and solar cell applications.
