Abstract

Liquid crystals, which are between the solid state of matter and the liquid state, are materials with interesting molecular structures. They are molecular materials that show both the properties of solid crystals and the properties of liquids. Materials whose physical properties change depending on the particle size, whose dimensions are at the nanometer level, are nanoparticles. Nanoparticles can be produced in many different types, depending on their size and structural shape. We obtained fluorescence graphs by combining liquid crystals and nanoparticles in solvents with three different characteristics. The liquid crystals we used in this study are 4-Pentylphenyl 4-Methoxybenzoate (4PP4MetoxB), 4-Pentylphenyl 4-Pentylbenzote (4PP4PentB), and 4-Pentylphenyl 4-(Octyloxy)Benzoate (4PP4OctoxB). Other materials we use are ZnS, CdSe, and CdS nanoparticles. We created new materials by combining these liquid crystals and nanoparticles in solvents. We examined whether the liquid crystals and nanoparticles in the newly formed materials interact in solvents and how the fluorescence graphs change according to the fluorescence graphs of liquid crystals.

Sıvı kristaller ve nanopartikül arasındaki etkileşimlerin belirlenmesi üzerine çalışma: Nanopartikül katkılı sıvı kristallerin floresan spektrumları

Abstract

Maddenin katı hali ile sıvı hali arasında bulunan sıvı kristaller ilginç moleküler yapılara sahip malzemelerdir. Hem katı kristallerin özelliklerini hem de sıvıların özelliklerini gösteren moleküler malzemelerdir. Fiziksel özellikleri parçacık boyutuna bağlı olarak değişen, boyutları nanometre düzeyinde olan malzemeler nanoparçacıklardır. Nanopartiküller boyutlarına ve yapısal şekillerine bağlı olarak birçok farklı tipte üretilebilir. Sıvı kristaller ve nanoparçacıkları üç farklı özellikteki çözücülerde birleştirerek floresans grafikleri elde ettik. Bu çalışmada kullandığımız sıvı kristaller 4-Pentilfenil 4-Metoksibenzoat (4PP4MetoxB), 4-Pentilfenil 4-Pentilbenzot (4PP4PentB) ve 4-Pentilfenil 4-(Oktiloksi)Benzoattır (4PP4OktoksB). Kullandığımız diğer malzemeler ZnS, CdSe ve CdS nanoparçacıklarıdır. Bu sıvı kristalleri ve nanopartikülleri solventlerde birleştirerek yeni malzemeler yarattık. Yeni oluşan malzemelerdeki sıvı kristaller ve nanoparçacıkların çözücüler içinde etkileşime girip girmediğini ve sıvı kristallerin floresans grafiklerine göre floresans grafiklerinin nasıl değiştiğini inceledik.
