Electrochromic and photovoltaic applications of benzotriazole bearing donor acceptor type conjugated polymers Baran, Derya; Toppare, Levent Kamil; Department of Chemistry (2010) Organic semi-conductors are of great interest since these compounds can be utilized as active layers in many device applications such as ECDs, LEDs and solar cells. Incorporating the benzotriazole units into the polymer backbone enhances the optical properties of donor units. Hexyl thiophene and pyrrole are commonly used as electron donor materials. Benzotriazole can be coupled to hexyl thiophene or pyrrole to yield materials which can be polymerized to give donor acceptor type polymers. These materials are...
Polymer white light emitting diodes applications of benzotriazole and fluorene derivatives Koçak, Güler; Çırpan, Ali; Department of Chemistry (2015) In this thesis, white polymer light emitting diodes (WPLEDs) were constructed using benzotriazole and fluorene containing conjugated polymers. For this purpose, three different blue and four different orange emitting conjugated polymers with different end cappers were used. The method that was used throughout the thesis included mixing of two polymers (blue and orange emitting) having different weight ratios in a common solvent. These solutions were coated on ITO-glass substrates by spin-coating technique w...
Synthesis and optoelectronic applications of benzotriazole and dibenzosilole based alternating copolymers Erlik, Ozan; Çırpan, Ali; Department of Chemistry (2014) Dibenzosilole synonym of silafluorene based polymers have been extensively used as the donor moiety in D-A approach for several years for optoelectronic applications like electrochromic (EC) devices, organic light emitting diodes (OLEDs), organic field effect transistors (OFETs) and most widely organic photovoltaics (OPVs). Moreover, chalcogenophenes such as thiophene and selenophene are used as an energy bridge between the donor and acceptor units to adjust the electronic and optical properties of the conj...
Investigation of optoelectronic properties of benzotriazole and thiazole bearing conjugated polymers Ünay, Hakan; Çırpan, Ali; Department of Polymer Science and Technology (2019) This thesis deals with the design, synthesis and characterization of conjugated polymers P1 and P2 that have potential application in organic solar cell. Polymer design was accomplished by using band gap engineering method. According to that, benzodithiophene (BDT) and silafluorene were chosen as donor groups in P1 and P2 respectively. The acceptor parts were the same for both polymers including benzotriazole (BTZ) and thiazole group. According to electrochemical studies both polymers were having n-dopable ...
Benzoselenadiazole, quinoxaline and thienothiophene based monomers ; electrochemical and spectroelectrochemical properties Toksabay, Sinem; Toppare, Levent Kamil; Department of Chemistry (2014) A new age had been started in macromolecular science with the invention of conducting polymers and they have gained considerable attention due to the their advantages of low cost, high molecular weight, easy fabrication and compability with flexible substrates. It was found that they can be used in many fields, such as organic light emitting diodes, electrochromic materials, organic solar cellsr, organic field effect transistors and sensors . Donor-acceptor phenomenon, which provide the band gap altenation ...
