Bu çalışmada, N,N’-(glycine tert-butylester)-3,4,9,10-perylenediimide (FY1) LangmuirBlodgett
(LB) filmlerin oda sıcaklığında uçucu organik buharlara karşı şişme
davranışları incelenmiştir. Bu ince filmlerin kloroform, benzen ve toluen buharlarına
karşı tepkileri Kuartz Kristal Mikrobalans tekniği kullanılarak ölçülmüştür. Organik
buhar moleküllerinin absorbsiyonu esnasında kütle değişimine bağlı rezonans frekansındaki değişim, FY1 ince filmlerinin şişme davranışı ile açıklanabilir. FY1 LB
filmlerin bu çalışma için seçilen organik buharlara karşı tepkisi bu organik buharların
fiziksel özellikleri ele alınarak incelenmiş ve bu ince filmlerin kullanılan organik
buharlar içerisinde en çok kloroform buharına karşı duyarlı olduğu gözlenmiştir.

Swelling behaviour of perylendiimide langmuirblodgett films and organic vapor sensing applications

Öz

In this study, the swelling behaviours of the N,N’-(glycine tert-butylester)-3,4,9,10-
perylenediimide (FY1) Langmuir-Blodgett (LB) films were investigated with respect to
volatile organic compounds (VOCs) at room temperature. The sensing responses of the
films against to chloroform, benzene and toluene vapors were measured by Quartz
Crystal Microbalance (QCM) method. The changes in resonance frequency associated
with mass changes can be attributed to the swelling behaviour of FY1 thin films during
organic vapor molecules absorption. The response of FY1 LB films to the choosed
VOCs has been investigated in conditions of physical properties of the solvents, and the
films were obtain to be largely sensitive to chloroform vapor compared to other studied
vapors.
