Double helicenes are appealing chiral frameworks. Their π-extension is desirable to achieve (chir)optical response in the visible and near-infrared (NIR) region, but access higher double [n]helicenes (n≥8) has remained challenging. Herein, we report an unprecedented π-extended [9]helicene (D9H), unambiguously revealing its structure by single-crystal X-ray diffraction. D9H shows remarkable NIR emission from 750 1100 nm with a high photoluminescence quantum yield of 18 %. In addition,...
Photosensitizers to precise target and change fluorescence upon light illumination could accurately self-report where when the photosensitizers work, enabling us visualize therapeutic process precisely regulate treatment outcomes, which is unremitting pursuit of precision personalized medicine. Here, we report self-immolative by adopting a strategy light-manipulated oxidative cleavage C═C bonds that can generate burst reactive oxygen species, cleave release self-reported red-emitting...
Abstract A negatively curved aza‐nanographene (NG) containing two octagons was synthesized by a regioselective and stepwise cyclodehydrogenation procedure, in which double aza[7]helicene simultaneously formed as an intermediate. Their saddle‐shaped structures with negative curvature were unambiguously confirmed X‐ray crystallography, thereby enabling the exploration of structure–property relationship photophysical, electrochemical conformational studies. Moreover, assembly octagon‐embedded...
This work describes a facile yet powerful approach to energy-transfer NMOF (nanoscale metal–organic framework) fabrication for ratiometric peroxynitrite (ONOO<sup>−</sup>) sensing.

Abstract Imaging abnormal copper/iron with effective fluorescent tools is essential to comprehensively put insight into many pathological events. However, conventional coordination‐based detection mired in the fluorescence quenching induced by paramagnetic Cu(II)/Fe(III). Moreover, strong chelating property of probe will consume dissociative metal ions and inevitably interfere physiological microenvironment. Here, a new strategy developed employing this aberrant Cu(II)/Fe(III) catalyze bond...
A benzo[ rst ]pentaphene (BPP) substituted by an isopropoxy group (BPP-OiPr) was synthesized in a facile manner. Its photophysical properties were investigated UV–vis absorption and fluorescence spectroscopy compassion to pristine BPP its oxidation product, ]pentaphene-5,8-dione (BPP-dione). BPP-OiPr exhibited significantly enhanced photoluminescence quantum yield (PLQY), reaching 73% comparison (13%). BPP-dione, when compared the parent BPP, also displayed improved emission from first...
Six thiophene-based chalcone derivatives were synthesized, and their structure–property relationship was investigated systematically. Small molecules as they are, have showed favorable <italic>Φ</italic> <italic>σ</italic> values in the near-IR region.
Reductive cleavage of alkenes is rarely reported in synthetic chemistry. Here we report a unique H2S-mediated reductive C[double bond, length as m-dash]C bonds under mild conditions, which successful new strategy for the design probes effective sensing H2S with turn-on dual-color fluorescence. A short series phenothiazine ethylidene malononitrile derivatives were shown to react H2S, via intramolecular cyclization reactions form thiophene rings. Enlightened by this reaction mechanism, four...

Herein we present a synthesis of an S-shaped double helicene with fused imide moieties, achieving contorted aromatic diimide (DHDI) good fluorescence properties in both solution and the solid state. DHDI demonstrates distinct mechanofluorochromism from yellow to green emission under grinding its crystalline powder.
Abstract The development of helicenes with strong chiroptical response and controlled photophysics is highly desirable but challenging. In this work, double thia/sulfone[7]helicenes were synthesized to investigate the heteroatom effect on photophysical properties heterohelicenes through comparison previously reported oxa[7]helicene. By variation embedded heteroatoms from oxygen sulfur, absorption emission significantly red‐shifted, along improved luminescence dissymmetry factor ( g lum )....
