| 1 | Tetraphenylethylene-BODIPY aggregation-induced emission luminogens for near-infrared polymer light-emitting diodes显示文摘The aggregation-induced emission(AIE) phenomenon provides a new direction for the development of organic light-emitting devices. Here, we present a new class of emitters based on 4,4-difluoro-4-bora-3 a,4 a-diaza-s-indacene(BODIPY), functionalized at different positions with tetraphenylethylene(TPE), which is one of the most famous AIE luminogens. Thanks to this modification, we were able to tune the photoluminescence of the BODIPY moiety from the green to the near-infrared(NIR)spectral range and achieve PL efficiencies of ~50% in the solid state. Remarkably, we observed an enhancement of the AIE and up to ~100% photoluminescence efficiencies by blending the TPE-substituted BODIPY fluorophores with a poly[(9,9-di-noctylfluorene-2,7-diyl)-alt-(benzo[2,1,3]thiadiazol-4,7-diyl)](F8 BT) matrix. By incorporating these blends in organic lightemitting diodes(OLEDs), we obtained electroluminescence peaked in the range 650–700 nm with up to 1.8% external quantum efficiency and ~2 m W/cm2 radiance, a remarkable result for red/NIR emitting and solution-processed OLEDs. | Sebnem Baysec Alessandro Minotto Patrick Klein Simone Poddi Andrea Zampetti Sybille Allard Franco Cacialli Ullrich Scherf | 2018 | Science China Chemistry2018，61，8： | 6 |

| 7 | Visible light communication with efficient far-red/near-infrared polymer light-emitting diodes显示文摘Visible light communication(VLC)is a wireless technology that relies on optical intensity modulation and is potentially a game changer for internet-of-things(IoT)connectivity.However,VLC is hindered by the low penetration depth of visible light in non-transparent media.One solution is to extend operation into the“nearly(in)visible”near-infrared(NIR,700-1000 nm)region,thus also enabling VLC in photonic bio-applications,considering the biological tissue NIR semitransparency,while conveniently retaining vestigial red emission to help check the link operativity by simple eye inspection.Here,we report new far-red/NIR organic light-emitting diodes(OLEDs)with a 650-800 nm emission range and external quantum efficiencies among the highest reported in this spectral range(>2.7%,with maximum radiance and luminance of 3.5 mW/cm^(2) and 260 cd/m^(2),respectively).With these OLEDs,we then demonstrate a“real-time”VLC setup achieving a data rate of 2.2 Mb/s,which satisfies the requirements for IoT and biosensing applications.These are the highest rates ever reported for an online unequalised VLC link based on solution-processed OLEDs. | Alessandro Minotto Paul A.Haigh Łukasz G.Lukasiewicz Eugenio Lunedei Daniel T.Gryko Izzat Darwazeh Franco Cacialli | 2020 | Light(Science & Applications)2020，9，1： | 1 |

| 13 | A Transparent Ultrasound Array for Real-Time Optical,Ultrasound,and Photoacoustic Imaging显示文摘Objective and Impact Statement.Simultaneous imaging of ultrasound and optical contrasts can help map structural,functional,and molecular biomarkers inside living subjects with high spatial resolution.There is a need to develop a platform to facilitate this multimodal imaging capability to improve diagnostic sensitivity and specificity.Introduction.Currently,combining ultrasound,photoacoustic,and optical imaging modalities is challenging because conventional ultrasound transducer arrays are optically opaque.As a result,complex geometries are used to coalign both optical and ultrasound waves in the same field of view.Methods.One elegant solution is to make the ultrasound transducer transparent to light.Here,we demonstrate a novel transparent ultrasound transducer(TUT)linear array fabricated using a transparent lithium niobate piezoelectric material for real-time multimodal imaging.Results.The TUT-array consists of 64 elements and centered at~6 MHz frequency.We demonstrate a quad-mode ultrasound,Doppler ultrasound,photoacoustic,and fluorescence imaging in real-time using the TUT-array directly coupled to the tissue mimicking phantoms.Conclusion.The TUT-array successfully showed a multimodal imaging capability and has potential applications in diagnosing cancer,neurological,and vascular diseases,including image-guided endoscopy and wearable imaging. | Haoyang Chen Sumit Agrawal Mohamed Osman Josiah Minotto Shubham Mirg Jinyun Liu Ajay Dangi Quyen Tran Thomas Jackson Sri-Rajasekhar Kothapalli | 2022 | Biomedical Engineering Frontiers2022，3，1： | 0 |
| 14 | Towards efficient near-infrared fluorescent organic light-emitting diodes显示文摘The energy gap law(E_(G)-law)and aggregation quenching are the main limitations to overcome in the design of near-infrared(NIR)organic emitters.Here,we achieve unprecedented results by synergistically addressing both of these limitations.First,we propose porphyrin oligomers with increasing length to attenuate the effects of the E_(G)-law by suppressing the non-radiative rate growth,and to increase the radiative rate via enhancement of the oscillator strength.Second,we design side chains to suppress aggregation quenching.We find that the logarithmic rate of variation in the non-radiative rate vs.E_(G)is suppressed by an order of magnitude with respect to previous studies,and we complement this breakthrough by demonstrating organic light-emitting diodes with an average external quantum efficiency of-1.1%,which is very promising for a heavy-metal-free 850 nm emitter.We also present a novel quantitative model of the internal quantum efficiency for active layers supporting triplet-to-singlet conversion.These results provide a general strategy for designing high-luminance NIR emitters. | Alessandro Minotto Ibrahim Bulut Alexandras G.Rapidis Giuseppe Carnicella Maddalena Patrini Eugenio Lunedei Harry L.Andersonand Franco Cacialli | 2021 | Light(Science & Applications)2021，10，2： | 0 |
