Lub benzo[c][1,2,5]thiadiazole nucleus yog lub qhov dej zoo-tsim hluav taws xob- tsis muaj lub tsev thaiv feem ntau siv rau hauv cov ntaub ntawv chemistry vim nws cov qauv geometry thiab cov hluav taws xob muaj zog - txais cov yam ntxwv. Kev taw qhia tswv yim ntawm fluorine atoms ntxiv txhim kho cov hluav taws xob- rho tawm ntawm cov tub ntxhais thaum cuam tshuam cov khoom ntim molecular los ntawm kev sib cuam tshuam ntawm halogen. Ob pawg boronate ester muab cov khoom siv hluav taws xob orthogonal nyob rau ntawm qhov sib txawv ntawm qhov tsis sib haum xeeb ntawm cov khoom muaj zog, ua rau kev tsim kho ntawm cov kab txuas txuas txuas txuas ntxiv los ntawm cov kab ke los yog ob qho tib si hla - kev sib txuas lus. Pinacol tiv thaiv pab pawg tiv thaiv cov boronic acids los ntawm oxidation ntxov ntxov thaum tseem tshem tau yooj yim nyob rau hauv me me transesterification tej yam kev mob. Qhov kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob muaj zog- tsis muaj qhov tseem ceeb nrog ob lub npog ntsej muag - cov neeg koom ua ke ua rau cov molecule no yog ib qho tseem ceeb ntawm kev tsim cov neeg pub dawb- txais cov khoom siv nrog cov khoom siv hluav taws xob zoo.

Organic Photovoltaic Khoom
Hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tsis zoo no benzothiadiazole ua haujlwm tseem ceeb hauv lub tsev thaiv rau kev sib xyaw ua ke qis -bandgap conjugated polymers thiab cov molecules me me rau cov hnub ci loj heterojunction. Cov tub ntxhais electron- tsis muaj peev xwm ua raws li qhov chaw txais khoom thaum copolymerized nrog electron- nplua nuj pub dawb xws li fluorene, carbazole, lossis benzodithiophene los ntawm Suzuki polycondensation. Cov txiaj ntsig pub dawb- txais cov polymers nthuav tawm dav dav dav dav dav mus rau hauv thaj tsam ze ntawm -infrared, ua kom muaj txiaj ntsig zoo ntawm photon thiab kev hloov hluav taws xob siab hauv cov khoom siv photovoltaic.

Organic Field-Cov nyhuv Transistors
Cov qauv nruj, qauv qauv thiab muaj zog electron affinity ntawm cov compound no ua rau nws muaj txiaj ntsig rau kev tsim n-hom thiab ambipolar semiconductors rau cov organic teb- cuam tshuam transistors. Kev koom ua ke rau hauv cov pob txha polymer conjugated los ntawm ob qho kev hla - kev sib txuas cov tshuaj tiv thaiv yields cov ntaub ntawv nrog cov khoom siv hluav taws xob siab thiab kev ruaj ntseg zoo heev. Cov tshuaj fluorine hloov mus ntxiv txhim kho cov yam ntxwv ntawm kev thauj mus los ntawm electron los ntawm kev txo qis qis qis ntawm lub zog molecular orbital zog thiab txhawb nqa cov khoom ntim hauv cov yeeb yaj kiab nyias.

Nyob ze -Infrared Fluorescent Probes
Qhov txuas txuas ntxiv thiab muaj zog intramolecular nqi hloov pauv cov yam ntxwv ntawm cov khoom sib txuas uas tau npaj los ntawm lub tsev thaiv no ua rau muaj kev txhim kho ze ntawm -infrared fluorescent dyes rau kev siv tshuaj lom neeg. Lub benzothiadiazole core muab tshwj xeeb photostability thiab quantum yields, thaum lub boronate leeg tso cai txuas ntawm solubilizing pawg thiab phiaj ligands. Cov kev sojntsuam no raug tshawb xyuas rau qhov sib sib zog nqus- cov duab kos duab, fluorescence- coj kev phais, thiab paub txog cov tshuaj lom neeg muaj feem cuam tshuam rau hauv ib puag ncig nyuaj.

Covalent Organic Framework Kev Tsim Kho
Raws li ib qho nyuaj, linear tsev thaiv nrog ob lub boronate functionalities, cov compound no yog ua hauj lwm nyob rau hauv lub synthesis ntawm boronate ester - txuas covalent organic moj khaum los ntawm condensation nrog polyhydroxy aromatics. Cov ntaub ntawv ntxeem tau ua ke ua ke cov khoom siv hluav taws xob- tsis muaj tus cwj pwm ntawm benzothiadiazole core nrog zoo- cov txheej txheem ntawm pore, ua rau cov ntawv thov hauv cov roj cia, sib cais, thiab cov catalysis heterogeneous. Cov fluorine hloov pauv tuaj yeem cuam tshuam lub hauv paus kev ruaj ntseg thiab cov qhua kev sib cuam tshuam los ntawm hydrophobic thiab halogen bonding cuam tshuam.
