Kodi Phenylacetylene CAS 536-74-3 ndi chiyani?

BKulumikizana kwa kaboni-kaboni katatu mu phenylacetylene ndi mgwirizano wawiri mu mphete ya benzene kumatha kupanga dongosolo lolumikizana, lomwe lili ndi kukhazikika kwina. Nthawi yomweyo, dongosolo lolumikizana limapangitsanso phenylacetylene kukhala ndi mphamvu yamphamvu ya ma elekitironi, ndipo ndikosavuta kuchita zinthu zosiyanasiyana zosinthira. Chifukwa chakuti lili ndi ma bond atatu ndi ma bond awiri a kaboni-kaboni osakhuta, phenylacetylene ili ndi mphamvu yamphamvu. Phenylacetylene imatha kuchita zinthu zina ndi hydrogen, halogen, madzi, ndi zina zotero kuti ipange zinthu zofanana.

Kugwiritsa ntchito

1. Organic synthesis intermediate: Iyi ndiyo ntchito yake yaikulu.
(1) Kupanga mankhwala: Amagwiritsidwa ntchito popanga mamolekyu osiyanasiyana ogwira ntchito m'thupi, monga maantibayotiki ena, mankhwala oletsa khansa, mankhwala oletsa kutupa, ndi zina zotero. Gulu lake la alkyne likhoza kusinthidwa kukhala magulu osiyanasiyana ogwira ntchito kapena kutenga nawo mbali mu zochita za cyclization kuti apange mafupa ovuta.
(2) Kupanga zinthu zachilengedwe: Kumagwiritsidwa ntchito ngati maziko ofunikira popanga zinthu zachilengedwe zokhala ndi mapangidwe ovuta.
(3) Kupanga mamolekyulu ogwira ntchito: Amagwiritsidwa ntchito popanga zinthu zamakristalo amadzimadzi, utoto, zonunkhira, mankhwala a zaulimi, ndi zina zotero.
2. Sayansi ya zinthu:
(1) Choyambira cha polima yoyendetsa: Phenylacetylene imatha kusinthidwa kukhala polymer (monga kugwiritsa ntchito ma catalyst a Ziegler-Natta kapena ma catalyst achitsulo) kuti ipange polyphenylacetylene. Polyphenylacetylene ndi imodzi mwa ma polima oyendetsera oyendetsa omwe adaphunziridwa kale. Ili ndi mphamvu za semiconductor ndipo ingagwiritsidwe ntchito kupanga ma diode otulutsa kuwala (ma LED), ma transistors a field-effect (ma FET), masensa, ndi zina zotero.
(2) Zipangizo zamagetsi: Zochokera kuzinthu zake zimagwiritsidwa ntchito kwambiri pazinthu zogwirira ntchito monga ma organic light-emitting diodes (OLEDs), ma organic solar cells (OPVs), ndi ma organic field-effect transistors (OFETs) ngati ma core chromophores kapena ma electron transport/hole transport material.
(3) Mafelemu a zitsulo-zachilengedwe (MOFs) ndi ma polima ogwirizanitsa: Magulu a alkyne angagwiritsidwe ntchito ngati ma ligand kuti agwirizane ndi ma ayoni achitsulo kuti apange zipangizo za MOF zokhala ndi mapangidwe enaake a pore ndi ntchito zoyatsira mpweya, kusungira, kulekanitsa, kugawa mphamvu, ndi zina zotero.
(4) Ma dendrimer ndi mankhwala a supramolecular: Amagwiritsidwa ntchito ngati zomangira kuti apange ma dendrimer olondola komanso ogwira ntchito bwino komanso kutenga nawo mbali mu supramolecular self-assembling.
3. Kafukufuku wa mankhwala:
(1) Gawo lokhazikika la Sonogashira coupling reaction: Phenylacetylene ndi imodzi mwa ma model substrates omwe amagwiritsidwa ntchito kwambiri pa Sonogashira coupling (palladium-catalyzed cross-coupling ya terminal alkynes ndi aromatic kapena vinyl halides). Izi ndi njira yofunika kwambiri yopangira conjugated ene-yne systems (monga zinthu zachilengedwe, mamolekyulu a mankhwala, ndi kapangidwe ka zinthu zogwirira ntchito).
(2) Click chemistry: Magulu a alkyne omwe ali kumapeto amatha kuchita bwino ndi azides kuti alowe mu copper-catalyzed azide-alkyne cycloaddition (CuAAC) kuti apange mphete zokhazikika za 1,2,3-triazole. Iyi ndi njira yoyimira "click chemistry" ndipo imagwiritsidwa ntchito kwambiri m'magawo a bioconjugation, kusintha kwa zinthu, kupeza mankhwala, ndi zina zotero.
(3) Kafukufuku pa machitidwe ena a alkyne: Monga chitsanzo cha mankhwala ophunzirira machitidwe monga alkyne hydration, hydroboration, hydrogenation, ndi metathesis.
