Molecular imprinting has become a powerful tool for the preparation of three dimensional polymeric

materials with special recognition ability. The three dimensionally cross-linked polymeric materials are obtained by

polymerization of functional monomers in the presence of template molecule. Then, leaching of template molecules

by a leaching procedure generates the recognition cavities complementary to the shape, size and functional groups

of the template molecules. Thus, molecularly imprinted polymers are often used because of their stability, their

resistance to temperature and pressure, resistance to effects of the chemicals and their re-use, as well as their

selective properties against template molecule. Nowadays, molecular imprinting technique has been successfully

assembled with a several of analytical techniques in chromatography, sensor etc. Molecularly imprinted polymers

synthesized as a template molecule of linalool have been studied for the first time in the literature. In the synthesis

of molecularly imprinted polymers, methacrylic acid as a monomer and ethylene glycol dimethacrylate as crosslinker

were chosen. Imprinted polymers were synthesized by the suspension polymerization method. The carbon

paste was prepared by mixing the obtained imprinted polymers with graphite powder at appropriate ratios and

electrochemical measurements were made by filling this carbon paste into the hand-made electrodes.

Linalool Baskılı Polimer Sentezi

Spesifik tanıma özelliği bakımından molekül baskılama tekniği, üç boyutlu polimerik malzemelerin

hazırlanmasında önemli bir araç haline gelmiştir. Üç boyutlu olarak çapraz bağlanmış polimerik malzemeler, kalıp

molekülünün bulunduğu ortamdaki fonksiyonel monomerlerin polimerizasyonu ile elde edilirler. Daha sonra,

uygun sökme prosedürüyle kalıp molekülünün şekil, boyut ve fonksiyonel gruplarına ait tamamlayıcı tanıma

bölgeleri oluşturulur. Böylelikle, molekül baskılı polimerler, kalıp moleküle karşı seçici özellik göstermesinin yanı

sıra kararlı bir yapıda bulunması, sıcaklığa ve basınca karşı dayanıklı, kimyasallara karşı dirençli olmaları ve tekrar

kullanılabilmeleri gibi özelliklerinden dolayı sıklıkla kullanılmaktadır. Günümüzde, moleküler baskılama tekniği,

kromatografi, sensör vb. gibi çeşitli analitik tekniklerle başarı bir şekilde birleştirilmiştir. Linalool maddesinin

kalıp molekül olarak sentezlenen molekül baskılı polimerler, literatürde ilk kez bu çalışma ile yapılmıştır. Molekül

baskılı polimerlerin sentezinde, monomer olarak metakrilik asit, çapraz bağlayıcı olarak da etilenglikol dimetakrilat

seçilmiştir. Baskılı polimerler süspansiyon polimerizasyonu yöntemiyle sentezlenmiştir. Elde edilen baskılı

polimerler ile grafit tozunun uygun oranlarında karıştırılmasıyla karbon pasta hazırlanmış ve elde imal edilmiş olan

elektrotların içerisine bu pasta doldurularak elektrokimyasal ölçümler yapılmıştır.
