Raws li cov tshuaj dawb hmoov, diether fluorene yog ib yam tshiab ntawm cov khoom siv tshuaj lom neeg ua qoob loo nrog lub siab ruaj khov. Nws yog feem ntau yog siv los ua ke cov khoom siv raw ntawm polymer monomer (xws li epoxy resin, polycarbonate, polyester, polyether lossis polyether, thiab lwm yam) nrog cov kub tsis kam, zoo heev transparency thiab siab refractive index. Nrog rau qhov kev thov nce ntxiv rau polymer cov ntaub ntawv kho qhov muag xws li polycarbonate, polyacrylate thiab epoxy resin hauv Suav teb, daim ntawv thov kev ua lag luam zeem muag ntawm diether fluorene yog muaj peev xwm heev. Kev tshawb nrhiav thiab kev tsim khoom ntawm cov khoom siv sib txuas ntawm cov khoom noj khoom haus thiab nws cov khoom lag luam qis kuj tseem yog cov ncauj lus tshiab nyob hauv Suav teb. Chembook, txhawm rau txhawm rau txhim kho kev txhim kho ntawm cov ntaub ntawv polymer thiab cov ua kom zoo ntawm cov khoom siv hauv Suav teb, tsav cov thev naus laus zis ntawm cov liaj teb uas cuam tshuam. Ntxiv dag zog rau kev tshawb fawb thiab kev tsim kho biether fluorene synthesis technology yog qhov tseem ceeb rau kev tiv thaiv kev tshawb fawb thiab kev siv thev naus laus zis, kev siab thiab tshiab thev naus laus zis thiab kev txhim kho thiab kev sib raug zoo.
