Crystalline nanofiber photosensitizers with twisted dual-acceptors: high light harvesting and singlet oxygen quantum yield.

ABSTRACT: The development of heavy-atom-free crystalline photosensitizers is highly favorable for practical applications due to their inherent advantages in robustness, facile post-reaction removal, and recyclability. However, achieving such systems with high molar absorptivity (>50 000 M⁻¹ cm⁻¹) and singlet oxygen quantum yields (>70%) remains a critical challenge, as these properties are typically compromised by intermolecular π-π interactions in molecular systems. Herein, we present a donor-acceptor (D-A) molecule featuring a uniquely twisted dual-acceptor backbone (D-A-A-D), achieving both high molar absorptivity and efficient singlet oxygen generation in monomeric solution. Critically, this connection topology facilitates the formation of crystalline nanofibers through CH/π and electrostatic in
