Abstract AR
حضرت و شخصت سلسلتين من البلورات السائلة الثرموتروبية الدايمترية.
السلسلة الأولى هي دايمر (a، β-بس (4- (4-الكوكسي بنزويلوكسي)-2-هيدروكسي بنزلدين)) ثنائي أمينو ايثان nO2On.
السلسلة الثانية هي معقدات النحاس الثنائية للدايمرات المحضرة : (a، β-بس (4- (4-الكوكسي بنزويلوكسي)-2-هيدروكسي بنزلدين)) ثنائي امينو ايثان النحاس CunO2O2.
في هذه المركبات يتغير طول السلسلة الطرفية من 1 إلى 7 ذرة كاربون.
فحصت الصفات البلورية السائلة بواسطة المسح الشعوري التفاضلي و المجهر ذو الضوء المستقطب، دلت هذه الدراسة على امتلاك هذه المركبات أطوار وسطية نيماتية و سمكتية.
Abstract EN
-Two series of thermotropic liquid crystal dimers were prepared and characterized, the first series: α,β-bis (4-(4-Alkoxy benzoyloxy)-2-hydroxy Benzylidene) diamino ethane(nO2On).The second series, the copper(II) complexes of these dimers α,β-bis (4-(4-Alkoxy benzoyloxy)-2-hydroxy Benzylidene) diamino ethane copper (II) (Cu nO2On).
In these materials the length terminal alkyl chain is varied from 1 to 7 carbon atoms.
The liquid crystalline properties of these materials have been investigated using differential scanning calorimetry and optical microscopy.
This study revealed that these material exhibit nematic and smectic A
