Abstract
Self-assembled PtPFTPP via dominant F⋯F interaction restricts aggregation caused quenching (ACQ) in the solid state. This leads to longer-lived photoexcited triplet and thereby higher photocatalytic hydrogen evolution rate of 400 μmol g −1 h −1 compared to self-assembled PtTPP with noticeable ACQ.
