| 1 | Mitochondria-localized iridium(Ⅲ) complexes with anthraquinone groups as effective photosensitizers for photodynamic therapy under hypoxia显示文摘Photodynamic therapy(PDT)is a potential way for the tumor treatment.However,it notably suffers the limitation of hypoxia in solid tumors.Thus,it is significant to develop effective photosensitizers which can exhibit excellent therapeutic performance under both normoxia and hypoxia.Herein,we reported four ionic iridium(Ⅲ)complexes(Irl-Ir4)with anthraquinone groups which can regulate their excited state energy levels effectively.Among them,the energy gap of Ir1 was between 1.63 and 2.21 eV,which can match well with that of O2,and the HOMO energy of Ir1 is less than-5.51 eV.Compared with Ir2-Ir4,the luminescent quantum efficiency of Irl was the highest.Particularly,Ir1 can specifically target the mitochondria of the tumor cells.Meanwhile,Ir1 showed high singlet oxygen quantum yields(Ф△)in both solutions and living cells with low cytotoxicity.The results of PDT experiments revealed that Irl,as a photosensitizer,exhibited excellent therapeutic effect not only in normoxia but also in hypoxia condition.We believe that this work is meaningful for developing excellent PDT agents based on cyclometalated Ir(III)complexes via rational ligand modification. | Song Guo Meiping Han Ruizhe Chen Yanling Zhuang Liang Zou Shujuan Liu Wei Huang Qiang Zhao | 2019 | Science China Chemistry2019，62，12： | 1 |

| 3 | Plant Diversity of Maoershan National Forest Park显示文摘There are a wide variety of wild plants in Maoershan National Forest Park.According to a fiveyear survey,the plants are found to include 557 species belonging to 116 families and 335 genera.There are 10 dominant families,such as Asteraceae,Ranunculaceae,Rosaceae,Fabaceae,and Chenopodiaceae,including 251 species,accounting for 46.06% of the total.There are 9 dominant genera,such as Polygonum,Potentilla ,Viola ,Artemisia ,and Corydalis ,which include 82 species of plants,accounting for 14.72% of the total.This study statistically analyzed the diversity and function of plants in the park and classified useful plants to provide a basis for the conservation and development of plant resources in Maoershan National Forest Park. | ZHANG Meiping CONG Mingyang HAN Wenge GUO Xiaohong | 2019 | Journal of Landscape Research2019，11，5： | 0 |
| 4 | Design and Application of Electronic Atlas of Ornamental Flora in the Daqing Area显示文摘The electronic atlas of ornamental flora in the Daqing area selects 265 species of plants from 84 families.The video studio X5 software is used to edit and process pictures and text materials,and professional templates are used to make a media playback video combining picture materials,text description,background music,and subtitle dub.Each plant is provided with a Latin scientific name,Chinese name,taxonomic status,habitat,application and other morphological characteristics description and identification pictures.This paper expounds on the design idea and the whole production process of the atlas.The atlas is easy to search and browse and can provide a necessary reference for gardeners,botany lovers and students to know ornamental plants correctly,and to research,develop and utilize ornamental plants. | ZHANG Meiping GUO Xiaohong HE Lin HAN Wenge JIANG Sujun | 2020 | Journal of Landscape Research2020，12，2： | 0 |
