Purification Methods
1,5,7-Triazabicyclo[4.4.0]dec-5-ene crystallises from Et2O but readily forms white crystals of the carbonate. It is a strong base (see pK, i.e. about 100 times more basic than tetramethylguanidine). The picrate has m 220.5-222o (from EtOH). It forms the 5-nitro derivative m 14.5-160o that gives a 5-nitro nitrate salt m 100-101o (from EtOH/Et2O) and a 5-nitro picrate m 144-145o (from H2O) [McKay & Kreling Can J Chem 35 1438 1957, Schwesinger Chimia 39 369 1985, Hilpert et al.

Check Digit Verification of cas no
The CAS Registry Mumber 5807-14-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,0 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5807-14:
(6*5)+(5*8)+(4*0)+(3*7)+(2*1)+(1*4)=97
97 % 10 = 7
So 5807-14-7 is a valid CAS Registry Number.

Super alkali material and preparation method thereof, and organic light-emitting diode
-
Paragraph 0056-0060, (2022/03/18)
The invention discloses a super alkali material and a preparation method thereof, and an organic light-emitting diode. The super alkali material has a general structural formula as described in the specification. In the general structural formula, aromatic rings Ar1, Ar2, Ar3 and Ar4 are respectively and independently selected from substituted or unsubstituted aryl or heteroaryl groups; N is a nitrogen atom; E is the same or different, and each E is an sp2-hybridized carbon or nitrogen atom; and Cy1, Cy2, Cy3 and Cy4 are respectively and independently selected from substituted or unsubstituted heterocyclic rings. The electron injection performance of a device can be effectively improved by introducing a functional group with an alkaline acid dissociation constant (pKa), and a planar rigid structure is adopted, so the material is closely stacked to show high electron mobility, the glass-transition temperature (Tg) of the material is increased, and the stability of the device is improved. On the premise that HOMO and LUMO energy levels are maintained, injection energy barriers are reduced, turn-on voltage is reduced, and when the material serves as an electron transport material of the organic light-emitting diode, the material has the advantages of being high in carrier mobility, excellent in device performance, good in stability and the like.
