要旨

A series of chiral 9,9′-spirobi[fluorene] (SBF) derivatives with diphenylamino donor and cyano acceptor units were designed as a new family of circularly polarized luminescent materials. The designed SBF derivatives were successfully synthesized from 7,7′-dibromo-9,9′-spirobi[fluorene]-2,2′-diol. No racemization occurred in the synthetic sequence. Therefore, each enantiomer of the SBF derivatives can be prepared from the enantiomerically pure starting material. Absorption and fluorescence spectroscopy and theoretical calculations revealed that the phenylene linker between the donor/acceptor units and the SBF core has a great impact on their photophysical properties. In particular, the phenylene linker was found to induce a red shift in their emission bands. The obtained chiral SBF derivatives exhibited solvent-dependent circularly polarized luminescence owing to their donor–π–acceptor structures.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
