Uses
Used in Chemical Industry:
2-(4-METHOXYPHENYL)-4,6-DIPHENYLPYRYLIUM TETRAFLUOROBORATE is used as a catalyst for the visible photooxidization of dibenzothiiophenes. Its application in this process is due to its ability to facilitate the oxidation reaction under visible light, making it a valuable component in the synthesis of various chemical products.
2-(4-METHOXYPHENYL)-4,6-DIPHENYLPYRYLIUM TETRAFLUOROBORATE's role as a catalyst in the photooxidization process is significant because it helps to increase the efficiency and speed of the reaction without being consumed in the process. This makes it a sustainable and cost-effective choice for industrial applications involving the production of chemicals derived from dibenzothiophenes.
Check Digit Verification of cas no
The CAS Registry Mumber 2907-13-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2907-13:
(6*2)+(5*9)+(4*0)+(3*7)+(2*1)+(1*3)=83
83 % 10 = 3
So 2907-13-3 is a valid CAS Registry Number.

Polarity-sensitive triphenyl pyridinium fluorescent probe as well as preparation and application thereof
-
, (2020/12/08)
The invention discloses a polarity-sensitive triphenyl pyridinium salt fluorescent probe and preparation and application thereof. The structural general formula of the fluorescent probe is shown in the specification, and R1 is H, a halogen atom or a methoxy group; and R2 is alkyl or substituted alkyl. The pyridinium salt part in the fluorescent probe with the structure is used as an electron acceptor (Acceptor, A) and has very strong electron withdrawing capability, and meanwhile, the three benzene ring parts in the fluorescent probe are used as an electron donor (Donor, D) and can provide proper electron donating capability; the fluorescent probe with a D-A structure formed in this way has certain fluorescence capability and atypical AIE properties; the solid fluorescence quantum yield is20% or above; in a certain polarity range, along with the enhancement of the solvent polarity, the luminescence red shift in the solvent is realized, the fluorescence intensity is weakened, and the quantum yield is reduced.
