Phenylacetylene CAS 536-74-3
BThe carbon-carbon triple daim ntawv cog lus nyob rau hauv phenylacetylene thiab ob daim ntawv cog lus nyob rau hauv lub nplhaib benzene tuaj yeem tsim ib qho kev sib txuas, uas muaj kev ruaj ntseg. Nyob rau tib lub sij hawm, lub conjugated system kuj ua rau phenylacetylene muaj ib tug muaj zog affinity rau electrons, thiab nws yog ib qho yooj yim mus undergo ntau yam kev hloov pauv. Vim nws muaj triple bonds thiab unsaturated carbon-carbon ob daim ntawv cog lus, phenylacetylene muaj zog reactivity. Phenylacetylene tuaj yeem ua rau muaj kev cuam tshuam ntxiv nrog hydrogen, halogens, dej, thiab lwm yam los tsim cov khoom sib xws.

1. Organic synthesis intermediate: Qhov no yog nws lub ntsiab siv.
(1) Cov tshuaj synthesis: Nws yog siv los ua ke ntau yam khoom siv roj ntsha, xws li qee yam tshuaj tua kab mob, tshuaj tiv thaiv kab mob, tshuaj tiv thaiv kab mob, thiab lwm yam. Nws pab pawg alkyne tuaj yeem hloov mus rau ntau pawg neeg ua haujlwm lossis koom nrog cov tshuaj tiv thaiv cyclization los tsim cov pob txha nyuaj.
(2) Natural khoom synthesis: Nws yog siv los ua lub tsev tseem ceeb hauv kev tsim cov khoom ntuj tsim nrog cov qauv nyuaj.
(3) Functional molecule synthesis: Nws yog siv los ua cov khoom siv lead ua kua, dyes, fragrances, tshuaj ua liaj ua teb, thiab lwm yam.
2. Khoom siv science:
(1) Cov khoom siv hluav taws xob ua ntej: Phenylacetylene tuaj yeem ua polymerized (xws li siv Ziegler-Natta catalysts lossis hlau catalysts) los tsim cov polyphenylacetylene. Polyphenylacetylene yog ib qho ntawm cov khoom siv hluav taws xob ntxov tshaj plaws tau kawm. Nws muaj cov khoom siv hluav taws xob semiconductor thiab tuaj yeem siv los ua lub teeb-emitting diodes (LEDs), thaj chaw cuam tshuam transistors (FETs), sensors, thiab lwm yam.
(2) Optoelectronic cov ntaub ntawv: Nws cov derivatives yog dav siv nyob rau hauv cov khoom siv xws li cov organic teeb-emitting diodes (OLEDs), organic solar cells (OPVs), thiab organic field-effect transistors (OFETs) ua core chromophores lossis electron thauj / qhov chaw thauj khoom.
(3) Hlau-organic moj khaum (MOFs) thiab kev sib koom ua ke polymers: Cov pab pawg alkyne tuaj yeem siv los ua ligands los koom tes nrog cov hlau ions los tsim MOF cov ntaub ntawv nrog cov qauv pore tshwj xeeb thiab kev ua haujlwm rau roj adsorption, cia, sib cais, catalysis, thiab lwm yam.
(4) Dendrimers thiab supramolecular chemistry: Lawv yog siv los ua lub tsev blocks los ua ke cov txheej txheem meej thiab ua haujlwm tau zoo dendrimers thiab koom nrog supramolecular self-assembly.
3. Kev tshawb fawb tshuaj:
(1) Standard substrate rau Sonogashira coupling cov tshuaj tiv thaiv: Phenylacetylene yog ib qho ntawm feem ntau siv qauv substrates rau Sonogashira coupling (palladium-catalyzed cross-coupling ntawm davhlau ya nyob twg alkynes nrog aromatic los yog yas halides). Cov tshuaj tiv thaiv no yog ib txoj hauv kev tseem ceeb rau kev tsim cov kab ke ene-yne (xws li cov khoom siv ntuj, tshuaj molecules, thiab cov qauv tseem ceeb ntawm cov khoom siv ua haujlwm).
(2) Nyem chemistry: Lub davhlau ya nyob twg alkyne pawg tuaj yeem ua haujlwm zoo nrog azides kom tau txais tooj liab-catalyzed azide-alkyne cycloaddition (CuAAC) los tsim cov rings ruaj khov 1,2,3-triazole. Qhov no yog ib tug neeg sawv cev cov tshuaj tiv thaiv ntawm "nias chemistry" thiab yog dav siv nyob rau hauv lub teb ntawm bioconjugation, hloov khoom siv, tshuaj nrhiav pom, thiab lwm yam.
(3) Kev tshawb fawb txog lwm cov tshuaj tiv thaiv alkyne: Raws li cov qauv sib xyaw rau kev kawm cov tshuaj tiv thaiv xws li alkyne hydration, hydroboration, hydrogenation, thiab metathesis.
