3,3′,4,4′-Benzophenonetetracarboxylic dianhydride CAS:2421-28-5

"3,3', 4,4'-Benzophenonetetracarboxylic dianhydride, eo hape e tsejoang e le BPTCDA, ke motsoako oa lik'hemik'hale o feto-fetohang o sebelisoang haholo liindastering tse fapaneng. E 'ngoe ea tšebeliso ea eona ea mantlha ke lefapheng la mahlale a polymer. BPTCDA e sebetsa e le monomer ea bohlokoa ho etseng li-polymer tse sebetsang hantle le li-copolymer. Li-polymer tsena li bontša botsitso bo botle ba mocheso, matla a mechini le thepa ea motlakase. Li sebelisoa libakeng tse kang metsoako e tsoetseng pele, liphahlo, likhomaretsi le lisebelisoa tsa elektroniki. Li-polymer tse thehiloeng ho BPTCDA li tsebahala ka ho hanyetsa mocheso o phahameng le libaka tse thata, e leng se etsang hore li lokele liindasteri tsa lifofane, likoloi le tsa elektroniki. Ho feta moo, BPTCDA e bapala karolo ea bohlokoa k'hemistri ea thepa. Sebopeho sa eona se ikhethang le reactivity li etsa hore e be karolo ea bohlokoa tlhahisong ea lisebelisoa tse sebetsang joalo ka likristale tsa metsi, li-semiconductor tsa organic le metsoako ea photochromic. Lisebelisoa tsena li na le lits'ebetso mahlaleng a ponts'o, lisebelisoa tsa optical le li-sensor. Ho feta moo, BPTCDA e sebelisoa haholo ho etseng li-organic. Lihlopha tsa eona tsa carboxylic acid tse arabelang haholo li lumella ho thehoa ha metsoako e fapaneng e sebetsang le metsoako e sebetsang. Bafuputsi ba sebelisa BPTCDA e le moaho oa ho kopanya limolek'hule tse rarahaneng tsa tlhaho tse nang le thepa e lakatsehang bakeng sa meriana, lik'hemik'hale tsa temo le lik'hemik'hale tse ikhethang. Ho feta moo, motsoako ona o fumana thuso lefapheng la catalysis. Moralo oa eona o tiileng le lihlopha tse hulang lielektrone li etsa hore e be catalyst e sebetsang liketsong tse 'maloa, ho kenyeletsoa le oxidation, phokotso, le ho thehoa ha bond ea carbon-carbon. Li-catalyst tse thehiloeng ho BPTCDA li bontšitse reactivity e ntlafalitsoeng, khetho, le botsitso, tse nolofalletsang liphetoho tsa lik'hemik'hale tse sebetsang hantle le tse tsitsitseng. Ka bokhutšoanyane, 3,3', 4,4'-Benzophenonetetracarboxylic dianhydride, kapa BPTCDA, e na le lits'ebetso tsa bohlokoa saenseng ea polymer, k'hemistri ea thepa, synthesis ea organic le catalysis. Sebopeho sa eona se ikhethang le reactivity e feto-fetohang li etsa hore e be motsoako oa bohlokoa bakeng sa ho nts'etsapele li-polymer tse sebetsang hantle, thepa e sebetsang, le limolek'hule tse rarahaneng tsa organic. Mefuta e fapaneng ea lits'ebetso e etsa hore BPTCDA e be karolo ea bohlokoa ho ntšetseng pele tsoelo-pele ea theknoloji le lipatlisiso tsa mahlale.
