white light emission from a single Organic Molecule with dual phosphorescence at room temperature
Nature Communications, 2017Co-Authors: Zikai He, Weijun Zhao, Qian Peng, Guodong Liang, Zhigang Shuai, Ben Zhong TangAbstract:The development of single Molecule white light emitters is extremely challenging for pure phosphorescent metal-free system at room temperature. Here we report a single pure Organic phosphor, namely 4-chlorobenzoyldibenzothiophene, emitting white room temperature phosphorescence with Commission Internationale de l’Eclair-age coordinates of (0.33, 0.35). Experimental and theoretical investigations reveal that the white light emission is emerged from dual phosphorescence, which emit from the first and second excited triplet states. We also demonstrate the validity of the strategy to achieve metal-free pure phosphorescent single Molecule white light emitters by intrasystem mixing dual room temperature phosphorescence arising from the low- and high-lying triplet states. The development of single Molecule white light-emitters is extremely challenging for pure phosphorescent metal-free systems at room temperature. Here the authors show a single pure Organic room temperature phosphor, 4-chlorobenzoyldibenzothiophene, utilizing the emission from both T1 and T2 states.

White light emission from InGaN/Organic Molecule light-emitting diode
2013 Conference on Lasers and Electro-Optics Pacific Rim (CLEOPR), 2013Co-Authors: Yuk Fai Cheung, Hoi Wai Choi, Zujin Zhao, Ben Zhong Tang, Kam Sing WongAbstract:Aggregation-induced emission (AIE) Organic Molecule 4,7-Bis[4-(1,2,2-triphenylvinyl)phenyl]benzo-2,1,3-thiadiazole (BTPETD) was used as a top emitter on GaN-based light-emitting diode (LED) to produce white light. The fabricated hybrid Organic/inOrganic LED shows CIE coordinates of (0.32, 0.33) and 45.4% optical extraction efficiency from BTPETD layer with pump leakage of 17.3%. At driving current of 30 mA, the highest luminous efficacy of 123.8 lm/W was obtained for the hybrid devices which corresponded a luminance of 1.4 × 105 cd/m2. This result shows an effective and simple way to produce white LED for solid state lighting application.

inner salt shaped small molecular photosensitizer with extremely enhanced two photon absorption for mitochondrial targeted photodynamic therapy
Chemical Communications, 2017Co-Authors: Wenbo Hu, Tingchao He, Rongcui Jiang, Lin Li, Xiaomei Lu, Hui Zhao, Lei Zhang, Ling Huang, Wei HuangAbstract:Herein, we experimentally and theoretically demonstrate an unprecedentedly enhanced two-photon absorption in a small Organic Molecule by a simple introduction of an inner salt-shaped structure. Moreover, such an inner salt-shaped small Molecule also exhibits superior singlet oxygen quantum yield and fascinating structure-inherent mitochondrial-targeting ability for highly efficient two-photon photodynamic therapy via a mitochondrial apoptosis pathway.

role of molecular conformations in rubrene thin film growth
Physical Review Letters, 2005Co-Authors: Daniel Kafer, L Ruppel, Gregor Witte, Ch WollAbstract:A systematic analysis of the growth of rubrene (C{sub 42}H{sub 28}), an Organic Molecule that currently attracts considerable attention with regard to its application in molecular electronics, is carried out by using x-ray absorption spectroscopy and thermal desorption spectroscopy. The results allow us to unravel a fundamental mechanism that effectively limits Organic epitaxy for a large class of Organic Molecules. If the structure of the free Molecule differs substantially from that of the corresponding molecular structure in the bulk, the crystallization is severely hampered.
