Small mols. with circularly polarized luminescence (CPL) are especially valuable in solution-based applications, like chiroptical probes for effective sensing. Such application was not well explored due in part to hard introduction of appropriate triggerable fluorophores. An easily post-modifiable CPL-active scaffold (4) is reported, and a feasible strategy to construct chiroptical probes for sensing hypochlorous acid is further proposed. Helically chiral 4 with a 4,4′-bicarbazole scaffold exhibits a large Stokes shift ≤142 nm and glum value of 0.9 × 10-3. Through facile construction of phenothiazine moiety on 4, red-emitting compound 5 was obtained in high yield (85.3%), showing distinct optical and chiroptical responses towards hypochlorous acid with good liner relations and CPL sign blue-shifting of 120 nm in vitro. The probe is also applied to detect endogenous hypochlorous acid in living macrophages and can serve as a CPL sensor. Taking 5 as an application example, the authors envision that CPL-enabling scaffold 4 could find broad use in the design of more chiroptical probes.
