| titleOfInvention | 2,5-DISUBSTITUTED PYRIDINES, PROCESS FOR THE PREPARATION THEREOF, LIQUID CRYSTALLINE MATERIAL, AND ELECTRO-OPTICAL DEVICE |
| abstract | THE 2.5-DISUBSTITLED PYRIDINES OF THE INVENTION HAVE THE FORMULA: (CF DRAWING IN BOPI) R BEING CH2N1 OR CH2N1O, N 4-8. THEIR PREPARATION PROCESS CONSISTS OF REACTING A PYRYLIUM SALT OF FORMULA: (CF DRAWING IN BOPI) WITH THE ABOVE MEANINGS, ON AMMONIUM ACETATE IN AN ORGANIC MEDIUM. THE LIQUID CRYSTALLINE MATERIAL CONTAINS AT LEAST ONE OF THE ABOVE 2.5 DISUBSTITUTED PYRIDINS AND OR A COMPOUND OF THE FORMULA: (CF DRAWING IN BOPI) IN WHICH R CH2N1, EQUAL TO 1-9. THIS MATERIAL MAY CONTAIN ORGANIC DIELECTRIC AND DICHROIC COLOR. IT ENTERS, AS A SERVICE BODY 1, IN AN ELECTRO-OPTICAL DEVICE INTENDED TO DISPLAY AND TRANSFORM INFORMATION. |
