Synthesis and Applications of New Conjugated Polymeric Materials Based on Carborane

TÜBİTAK

349.100 TL

(Director)

15/04/2012-15/10/2014

Summary

In this study, in order to overcome the problems faced by the industrial field of conjugated polymers (insolubility, thermal, mechanical, optical and electrochemical instability, etc.) the inorganic and organic units will be melted in the same pot for producing new carborane based polymeric materials. In the first two years of the project, initially carborane based electron donor-acceptor-donor (D-A-D) type new inorganic-organic hybrid monomers will be designed and synthesized and then soluble conjugated polymers (low band gap, reversible electronic and optical properties, n- and/or  p-type doping behavior, fast switching of various redox states and different colors and environmetally and thermally stable novel florescent conjugated polymers) will be tried to obtain by use of electrochemical and chemical methods. While alkyl substituted 3,4-propylenedioxythiophene and carbazole units will be used as D unit, carborane units will be used as A unit.

When the materials designed in the project are moved successfully to the industrial fields such as electrochromic devices and LED applications, it will be brought to a solution to an industrial problem by using carborane chemicals. As a result, it will be the primary purpose and goal of our project to overcome the problem faced by industrial areas (electrochromic devices and LEDs) with the products based on special carboranes, which can be synthesized in our country.

Design, Synthesis and Technological Applications of New Boran Based Inorganic-Organic Hybrid Polymeric Materials

Summary

In literature, a terthiophene and carborane based electron donor-acceptor-donor type electroactive monomer was firstly synthesized successfully. Monomer was polymerized electrochemically and its electrochemical and optical properties were investigated. The presence of carborance unit in polymeric backbone provided a resistance to high potential values at ambient conditions. For example, 96% of optical properties of the polymers retained after one thousand cycles. Also, it is proved that silver ion can be removed without electrolysisor obtained as a metal by using polymer. The polymer films with a 1.64 eV band gap is a promising materials since it is an electrochromic materials due to its color changes at varios redox states. Finally, the polymer film was used for the construction of an electrochromic device.

Synthesis, Properties and Applications of New Functional Photochromic Materials

Summary

Among functional organic compounds, photochromic dithienylethene (DTE) derivatives are quite attractive materials due to their thermal stability and high fatigue resistance. Both properties (thermal stability and fatigue resistance) are indispensable for optoelectronic applications. However, some other properties of DTEs such as fast switching, high quantum yield and large differences between the absorption wavelengths of two isomers have also contributed to ever increasing popularity of these compounds which have found diverse applications as smart materials (e.g. molecular switches, optical data processing and storage devices, molecular probes, machines and imaging agents) in both bio-and nano- technological sciences as well as in materials science.

Herein, novel processable photochromic and redox active compounds will be designed, synthesized and characterized spectroscopically (UV-vis, Luminescence-fluorescence, FTIR, NMR, Mass Spectroscopy, Elementel Analysis, Cyclic Voltammetry). Furthermore, some applications of these novel compounds in materials science (as photochromic, electrochromic, dual chromic, photoconductive and thermo sensitive smart materials etc.) will be investigated.
