| 1 | Synthesis and characterization of dendronized hyperbranched polymers through the “A_3+B_2” approach显示文摘Dendronized hyperbranched polymer(DHP) is a new kind of polymer, which combines the advantages of dendrimers and hyperbranched polymers. In this work, two dendronized hyperbranched polymers, DHPG0 and DHPG1, were successfully prepared through the simple 'A_3+B_2' type Sonogashira coupling reaction. The nonlinear optical(NLO) effects of DHPG0 and DHPG1, characterized by the d33 values, were 183 and 220 pm V^(–1) respectively, higher than those of their analogues of dendronized polymers and dendrimers, thanks to the special topological structure. Also, the obtained polymers displayed excellent solubility, good processability, and high thermal stability. | Guangchao Liu Pengyu Chen Runli Tang Zhen Li | 2016 | Science China Chemistry2016，59，12： | 2 |
| 2 | Construction of deep-blue AIE luminogens with TPE and oxadiazole units显示文摘In this paper, two AIE-active luminogens (Oxa-pTPE and Oxa-mTPE) constructed from tetraphenylethene and oxadiazole units were successfully synthesized and their thermal, optical and electronic properties were investigated. By linking TPE to the oxadiazole core through meta-or para-position, the intramolecular conjugation is effectively controlled. Thanks to the intelligent molecular design and specific AIE feature, when fabricated as emissive layers in non-doped OLEDs, they exhibit blue or deep-blue emission with CIE coordinates of (0.17, 0.23) and (0.15, 0.12), and good efficiencies with ηC, max and ηP, max up to 1.52 cd A-1 and 0.84 Im W-1 , shedding some light on the construction of deep-blue AIE fluorophores. | HUANG Jing CHEN PengYu YANG Xiao TANG RunLi WANG Lei QIN JinQui LI Zhen | 2013 | Science China Chemistry2013，56，9： | 1 |
| 3 | New triphenylamine-based sensitizers bearing double anchoring units for dye-sensitized solar cells显示文摘Two organic sensitizers(LI-33 and LI-34) with double anchoring units were synthesized and utilized for dye sensitized solar cells(DSSCs), which contained thiophene or vinyl thiophene as π-bridge. The introduction of double anchoring units can change their absorption spectra and energy levels in a large degree, thus, the better light-harvesting ability and the convenient electron transfer along the whole molecule can be obtained. The solar cell based on LI-34 exhibited a broad incident photonto-current conversion efficiency(IPCE) spectrum and high conversion efficiency(η=6.05%) with coadsorbent CDCA. | Jie Shi Zhaofei Chai Runli Tang Jianli Hua Qianqian Li Zhen Li | 2015 | Science China Chemistry2015，58，7： | 0 |
