Khoom Description
2,3-Benzofluorene yog ib yam khoom uas muaj ntxhiab tsw.2,3-Benzofluorene yog soluble nyob rau hauv feem ntau cov organic solvents, tab sis tsawg dua nyob rau hauv dej.
Kev siv:
- Luminescent cov ntaub ntawv: 2, 3-Benzilfluorene yog xiav-emitting organic fluorescent dyes, yog dav siv nyob rau hauv fluorescent qhia, organic teeb-emitting diodes (OLEDs) thiab lwm yam teeb-emitting ntaub ntawv npaj.
- Organic Synthesis: 2,3-Benzofluorene kuj tseem siv tau los ua ib qho nruab nrab hauv cov organic synthesis cov tshuaj tiv thaiv rau kev sib txuas ntawm lwm cov organic compounds.
Txoj Kev Npaj:
- 2,3-Benzofluorene tuaj yeem npaj tau ntau txoj hauv kev, thiab ib txoj hauv kev yog los ua ke los ntawm kev sib txuas cov tshuaj tiv thaiv ntawm cov tshuaj tsw qab hydrocarbons. Tshwj xeeb, 2,3-benzofluorene tuaj yeem tau txais los ntawm kev siv cov tshuaj tiv thaiv ntawm bis-aromatic boronone (xws li naphth-2-ylboronic acid) thiab sulfoxide (xws li dimethyl sulfoxide) nyob rau hauv ib qho chaw nitrogen ntawm qhov tsim nyog. kub thiab nyob rau hauv lub xub ntiag ntawm ib tug catalyst.
