General Description

C37H40B2O4 is a chemical compound known as bisphenol A diglycidyl ether, commonly abbreviated as BADGE. It is a widely used epoxy resin and a component of many plastics and adhesives. BADGE is also used in the manufacturing of can coatings to protect against corrosion and as a component in food packaging materials. However, it has been the subject of controversy due to its potential to leach into food and beverages, leading to concerns about its potential toxic effects on human health. Studies have shown that exposure to BADGE may be linked to endocrine disruption and other health issues, leading to efforts to regulate its use in certain applications.

Check Digit Verification of cas no

The CAS Registry Mumber 474918-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,9,1 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 474918-36:
(8*4)+(7*7)+(6*4)+(5*9)+(4*1)+(3*8)+(2*3)+(1*6)=190
190 % 10 = 0
So 474918-36-0 is a valid CAS Registry Number.

Ter(9,9-diarylfluorene)s: Highly efficient blue emitter with promising electrochemical and thermal stability

Novel ter(9,9-diarylfluorene)s were synthesized by a Suzuki-coupling reaction of 2-bromofluorene (1) and 2,7-fluorenediboronic ester derivatives (3) with high isolated yields (63-86%). The X-ray structure analysis of ter(9,9′-spirobifluorene) (4aa) revealed that the conjugated chromophore adopts a helical conformation. This conformation effectively releases the steric interaction between the fluorene moieties and prevents inter-chromophore interactions. The introduction of aryl groups at the C9 position of fluorene was highly beneficial to the thermal and morphological stability of these oligomers. These terfluorenes exhibit intense blue fluorescence with excellent quantum yields both in solution (~100%) and in solid state (66-90%), and possess interesting reversible redox properties. Highly efficient blue light-emitting OLED devices were fabricated using 4aa and 4cc as emitters as well as hole transporters. The devices exhibit low turn-on voltage (~3 V) and high EL external quantum efficiency (2.5-3%). Copyright
