Qhov sib txawv tseem ceeb ntawm excimer thiab exciplex yog excimer muaj ob hom, whereas exciplex muaj ntau tshaj ob hom.
Ib qho excimer tuaj yeem piav qhia raws li lub neej luv luv dimeric lossis heterodimeric molecule uas tsim los ntawm ob hom uas tsawg kawg ib hom muaj lub plhaub valence nrog cov txheej txheem electron tiav. Exciplex thiab excimer zoo siab rau qee cov tshuaj tiv thaiv hauv cov organic chemistry.
Excimer yog dab tsi?
Ib qho excimer tuaj yeem piav qhia raws li lub neej luv luv dimeric lossis heterodimeric molecule uas tsim los ntawm ob hom uas tsawg kawg ib hom muaj lub plhaub valence nrog cov txheej txheem electron tiav. Lo lus excimer stands rau "zoo siab dimer." Feem ntau, excimers yog diatomic, thiab cov no muaj ob lub atoms lossis molecules uas tsis khi yog tias ob hom nyob hauv av.
Feem ntau, lub neej ntawm excimer luv luv, thiab nws ntsuas ntawm qhov ntsuas nanoseconds. Ntxiv mus, yog tias muaj coob tus ntawm cov atoms zoo siab tau sib koom ua ke, nws tsim Rydberg teeb meem pawg, thiab nws lub neej tuaj yeem nce ntxiv los ntawm ntau lub vib nas this.
Thaum xav txog qhov tsim ntawm lub xeev no, ib qho chaw hauv av-xeev molecule muaj cov khoom siv hluav taws xob nyob rau hauv qis tshaj qhov ua tau lub zog; Feem ntau, tsuas yog ob lub tshuab hluav taws xob nyob hauv ib lub orbital uas ob lub electrons yog qhov sib txawv ntawm lub xeev. HOMO yog qhov siab tshaj plaws nyob hauv molecular orbital, thaum LUMO yog qhov qis tshaj plaws uas tsis muaj lub cev molecular orbital. Ob lub orbitals no muaj qhov sib txawv ntawm lub zog, thiab qhov nqus ntawm lub teeb nrog tib lub zog raws li qhov sib txawv ntawm lub zog tuaj yeem ua rau kev tsim cov molecule lub xeev zoo siab. Ib qho excimer yog tsim thaum cov khoom dimer nyob rau hauv lub xeev zoo siab.
Exciplex yog dab tsi?
Exciplex yog ib lub sijhawm luv luv hauv lub xeev zoo siab uas tau tsim los ntawm ntau tshaj ob hom. Yog li ntawd, nws yog lub xeev zoo siab uas tsim ntawm ib lub molecule uas pub electrons thiab ib qho uas txais electrons.
Feem ntau, cov complexes yog qhov txaus siab rau lub teeb pom kev zoo uas lawv muaj. Peb tuaj yeem nkag siab txog exciplex emission los ntawm lub peev xwm lub zog daim duab ntawm exciplex-forming hom. Ib qho excimer kuj yog ib hom exciplex thiab tsuas muaj ob hom uas tsim cov molecule complex.
Vim tias muaj ntau dua ob lub monomers hauv ib qho exciplex, nws tsis ruaj khov thiab muaj qhov xwm txheej luv luv piv rau lwm hom kev zoo siab xws li excimers.
Qhov txawv ntawm Excimer thiab Exciplex yog dab tsi?
Ib qho excimer tuaj yeem piav qhia raws li lub neej luv luv lossis heterodimeric molecule uas tsim los ntawm ob hom uas tsawg kawg ib hom muaj lub plhaub valence nrog cov txheej txheem electron tiav. Exciplex yog ib tug luv luv-nyob molecule nyob rau hauv lub zoo siab lub xeev uas yog tsim los ntawm ntau tshaj ob hom. Qhov sib txawv tseem ceeb ntawm excimer thiab exciplex yog excimer muaj ob hom, whereas exciplex muaj ntau tshaj ob hom.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm excimer thiab exciplex hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Excimer vs Exciplex
Exciplex thiab excimer yog cov xeev zoo siab ntawm qee cov tshuaj lom neeg hauv cov tshuaj lom neeg. Ib qho excimer yog lub neej luv luv dimeric lossis heterodimeric molecule uas tsim los ntawm ob hom uas tsawg kawg ib hom muaj lub plhaub valence nrog ib qho kev ua tiav electron. Exciplex yog ib tug luv luv-nyob molecule nyob rau hauv ib tug zoo siab lub xeev uas yog tsim los ntawm ntau tshaj ob hom. Qhov sib txawv tseem ceeb ntawm excimer thiab exciplex yog excimer muaj ob hom, whereas exciplex muaj ntau tshaj ob hom.
