Synthesis

The target monomer was prepared by firstly converting the acid into the corresponding acid chloride, then condensing this withp-cyanophenol. The acid (17.32 g, 0.059 mol) was stirred with thionyl chloride (35.7 g, 0.3 mol) in the presence of DMF (2 drops) and 2,6-di-tert-butyl-4-methyl phenol (4.4 g, 0.02 mol). After ca. 25 min, by which time solution was achieved, the excess thionyl chloride was removed by rotary evaporation and high vacuum (1-2 h). The acid chloride residue was dis- solved in anhydrous chloroform (30 mL), then added slowly dropwise into a stirred solution of p-cyanophenol (7.03 g, 0.059 mol) and triethylamine (6.07 g, 0.06 mol) in chloroform (20 mL) at 0°C. After the addition the mixture was stirred at room temperature for 24 h and then chloroform (200 mL) added. This solution was washed with water (50 mL) followed by 2 N sodium hydroxide solution (3 x 50 mL) and water (2 x 50 mL). The organic layer was dried (MgSO,), evaporated, then subjected to flash chromatography, using dichloro- methane as both the solvent and the eluant. The monomer was finally recrystallized from isopropanol and shown to be pure by tlc. Yield: 16 g, 69%.

Check Digit Verification of cas no

The CAS Registry Mumber 83847-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,4 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83847-14:
(7*8)+(6*3)+(5*8)+(4*4)+(3*7)+(2*1)+(1*4)=157
157 % 10 = 7
So 83847-14-7 is a valid CAS Registry Number.

Photoorientation in hydrogen-bonded blends of liquid-crystalline polymers with a low-molecular photochromic dopant

Obraztsov,Bobrovsky,Shibaev

experimental part, p. 330 - 336 (2009/06/05)

A series of hydrogen-bonded blends of nematic liquid-crystalline copolymers with a low-molecular photochromic dopant and their covalent analogs were prepared. Their phase behavior and photooptical properties were studied. The introduction of a dopant increases considerably the isotropization temperatures of the systems. A comparative study of photoorientation processes in the blends and copolymers analogous to them was carried out. The induced dichroism in covalent systems is more pronounced than in similar hydrogen-bonded blends.
