569-06-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 569-06-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 569-06:
(5*5)+(4*6)+(3*9)+(2*0)+(1*6)=82
82 % 10 = 2
So 569-06-2 is a valid CAS Registry Number.

Improved solid-state photomechanical materials by fluorine substitution of 9-anthracene carboxylic acid

Zhu, Lingyan,Tong, Fei,Salinas, Christopher,Al-Muhanna, Muhanna K.,Tham, Fook S.,Kisailus, David,Al-Kaysi, Rabih O.,Bardeen, Christopher J.

, p. 6007 - 6015 (2014)

Four fluorinated derivatives of 9-anthracene carboxylic acid (9AC), a molecule that shows a reversible photomechanical response in its crystal form, have been synthesized and characterized. The spectroscopic properties and crystal structures of 4-fluoro-9-anthracene carboxylic acid (4F-9AC), 2-fluoro-9-anthracene carboxylic acid (2F-9AC), 10-fluoro-9-anthracene carboxylic acid (10F-9AC), and 2,6-difluoro-9-anthracene carboxylic acid (2,6DF-9AC) are all very similar to those of 9AC. However, their photomechanical properties vary widely. 405 nm light was used to induce [4 + 4] photodimerization and a mechanical response in crystalline microneedles and ribbons. Both the photodimer dissociation rate and the mechanical recovery varied by more than an order of magnitude, with 4F-9AC exhibiting the most rapid recovery time, on the order of 30 s. Nanoindentation measurements show that this crystal has a slightly reduced elastic modulus and a significantly reduced hardness, making it less brittle than the 9AC crystal. Large 4F-9AC crystals remain intact after irradiation, without fragmenting, while microneedles can undergo more than 100 mechanical bending cycles. Given the similarity of the crystal packing in all five molecules, the improved photomechanical properties must arise from subtle changes in intermolecular interactions or possibly differences in disorder. These results demonstrate that it is possible to significantly improve the properties of photomechanical materials through small modifications of the molecular structure.

KINETICS AND MECHANISM OF DIELS-ALDER ADDITIONS OF TETRACYANOETHYLENE TO ANTHRACENE DERIVATIVES-III EFFECT OF SUBSTITUENTS ON RATES AND INTERMEDIATE COMPLEX FORMATION

Roberts, R. M. G.,Yavari, F.

, p. 2657 - 2662 (1981)

In Diels-Alder additions of tetracyanoethylene to 1,2-, and 9-substituted anthracenes, formation constants (K) for the intermediate complexes have been separated from the global rate constant (K2obs).The relatively small range of values of K indicates a very small charge transfer in the complexes.The transition state for conversion of complex into adduct showed a marked degree of charge development, particularly for the 9-substituted derivatives (ρ=-7).Substituents in the outer rings gave good rate correlations with composite constants (?m+ + ?p+) with a ρ value of -3.The substituent effects are discussed in terms of these and other parameters.Values for equilibrium constants for the overall addition (Keq) are reported.

Restricted Rotation Involving the Tetrahedral Carbon. XLV. Appearance of a Maximum in the Rotational Barriers of 9-(1,1-Dimethyl-2-phenylethyl)triptycenes at a Medium-sized peri-Substituent

, p. 306 - 313 (2007/10/02)

Rotational isomers of seven peri-substituted 9-(1,1-dimethyl-2-phenylethyl)triptycene derivatives were stereoselectively synthesized and classical kinetics on rotational isomerization were studied.While compounds with relatively small peri-substituents (F
