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.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
