Cov Ntawv Thov
2,7 {- dibromo -}}}}}}}}} 9-ee- Colorister-9-Green Chemister, thiab cov khoom siv tshuaj txuj ci. Nws ua haujlwm nruab nrab hauv nruab nrab rau kev npaj ntawm fluorescent dyes, poov xab, thiab laser dyes, qhov twg ntawm xanthone core muab cov khoom muaj zog photophysical. Hauv kev tshawb fawb tshuaj, nws yog siv rau kev sib txuas ntawm kev ua haujlwm Xanthone derivatives, xws li Suzuki lossis Heck Remelations, cia cov lus qhia txog ntau cov neeg hloov chaw ntawm cov haujlwm bromine. Nws kuj pom cov ntawv thov hauv kev txhim kho cov organic semiconductors, cov photicalsals, thiab kev tshawb fawb txog cov qauv uas muaj ntxhiab thiab cov qauv muaj tswv yim ruaj khov thiab cov khoom siv hluav taws xob.
Cov txiaj ntsig
Cov txiaj ntsig ntawm 2,7 {- dibromo {}}}}}}}} 9-}} 9-} Lub bromine atoms ua raws li reactive tes rau xaiv hloov chaw lossis txuas ntawm cov kev tsim kho, cov ntaub ntawv, thiab cov khoom siv bioactive. Nws cov ntxhiab Xantovone core muab cov thermal siab thiab yees duab stability, uas yog qhov tseem ceeb rau cov ntawv thov fluorescent thiab Optoelectronic apps. Ib qho ntxiv, cov luam tawm cov khoom siv hluav taws xob tso cai rau cov kws tshawb fawb tsim qauv, kev ua kom haum, txhim kho kev ua haujlwm, thiab cov ntawv thov siv.
Tag
Hauv cov ntsiab lus, 2,7 {{{{{{} dibromo {}}} 9-}} 9-ib yog kev txhim kho cov synthesis, khoom siv cov kev tshawb fawb, thiab cov kev tshawb fawb tshuaj lom neeg. Nws cov ntawv thov suav nrog fluorescent dyes, photocatalysts, thiab kev ua haujlwm tau txais txiaj ntsig zoo nkauj, thaum lub zog ruaj khov, thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Raws li thov kom muaj kev ua tau zoo dyes thiab cov khoom siv ua haujlwm loj, cov compound no tseem yog qhov cuab yeej tseem ceeb rau kev tsim kho cov tshuaj lom neeg thiab cov khoom siv.
