However, thin films of aggregated, enantiopure prolinol-derived squaraine molecules (ProSQ-C16) exhibit an unusually large excitonic CD signal, although the underlying mechanism is not yet known. In this study, we employ steady-state and ultrafast transient absorption spectroscopy to investigate the nature and dynamics of excitons in aggregates of enantiopure and racemic ProSQ-C16 thin films. Highly resembling transient responses of enantiopure thin films under excitations at different photon energies strongly indicate that a single type of aggregate dominates the linear optical response, that is, a strong red-shifted (J-like) and weak blue-shifted (H-like) absorption band. On the other hand, the transient properties of the racemic thin film deviate from this pattern and remain largely ambiguous. The short lifetime of excited states and coherent oscillations present in the dynamics of the transient absorption signal indicate that the early time dynamics are governed by a transition towards a dark intermediate state, which might arise from intermolecular charge transfer with potential contributions from the coupling of excitons to the vibrations. This non-radiative relaxation pathway explains the unusually weak fluorescence of the predominately J-like behaving aggregate.

To overcome limitations such as tissue penetration depth and controllability of internal light sources, this study introduces an antibacterial gel electrochemiluminescence device for the treatment of diabetic wounds and the monitoring of wound bacteria. We deploy a large-area luminescent device combining flexible screen-printed electrodes and a dual-network hydrogel, in which photodynamic therapy is driven by Ru@COFs' nanoconfinement-enhanced near-infrared electrochemiluminescence to achieve a deeper and safer antibacterial effect. The custom-sized screen-printed electrodes inherit the inborn electrochemical sensing function and enable intimate contact between reactive oxygen species and the wound. The device avoids physical light sources and provides a new paradigm for developing miniaturized integrated diagnostic and therapeutic wearable devices.</p>","PeriodicalId":72127,"journal":{"name":"Aggregate (Hoboken, N.J.)","volume":"6 3","pages":""},"PeriodicalIF":13.9,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agt2.703","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
