Synthesis of Phenanthroline-Functionalized Phosphazene Based Metallosupramolecular Polymers and Their Stimuli-Responsive Properties

Sezer, Selda
A series of phenanthroline-functionalized phosphazene based metallo-supramolecular polymers (PFP-MSP) was synthesised using a two-step reaction strategy. In first step, three phenanthroline unit containing monomer (PFP-M) was prepared from 5,6-dihydroxy-1,10-phenanthroline and hexachlorocyclotriphosphazene by condensation reaction. Then, this PFP-M was reacted with different metal ion salts (Co, Ni, Cu, Fe, Eu, La, Tb, Lu ions) and resulting for the metallo-supramolecular polymers bearing phosphazene structure. Obtained PFP-MSPs were characterized by spectroscopic analysis, elemental analysis, Scanning electron microscopy measurement and SEM-energy dispersive X-ray spectrometry techniques. Stimuli responsible and opto-electronic properties of synthesized PFP-MSPs were also studied for different external stimulating factors, such as electrochemical or the addition of competitive complexing ligands by UV-Vis spectroscopy and electroanalytic techniques. As a result, prepared PFP-MSPs are good alternatives for photochromic, electrochromic, opto-electronic and smart material applications.


Synthesis and Stimuli-Responsive Properties of Metallo-Supramolecular Phosphazene Polymers Based on Terpyridine Metal Complexes
In this study, terpyridine functionalized phosphazene based metallo-supramolecular polymers were synthesized by three step reaction method. In the first step, 4 '-(4-aminophenyl)-2,2 ':6 ',2 ''-terpyridine was synthesized with p-nitro benzaldehyde and 2-acetylpyridine. Then, the monomer containing six terpyridine (TPY) units attached to the phosphazene was prepared from 4 '-(4-aminophenyl)-2,2 ':6 ',2 ''-terpyridine and hexachlorocyclotriphosphazene by a condensation reaction. Finally, metallo-supramolecula...

Sahin, E; Camurlu, P; Toppare, Levent Kamil; Mercore, VM; Cianga, I; Yagci, Y (Wiley, 2005-12-01)
Thiophene functionalized polystyrene samples (TFPS) were synthesized by atom transfer radical polymerization (ATRP) of styrene, followed by Suzuki coupling with 3-thiophene (Th) boronic acid. Conducting graft polymer of TFPS with thiophene was achieved at 1.5 V in tetrabutylammonium tetrafluoroborate/dichloromethane (TBAFB/DM) by electrochemical methods. Spectroelectrochemical analysis of the resulting copolymers [P(TFPS-co-Th)] reflected electronic transitions at 449, 721 and 880 nm, revealing pi - pi* tra...
Kinetic study of the reaction between hydroxyl-terminated polybutadiene and isophorone diisocyanate in bulk by quantitative FTIR spectroscopy
Kincal, D; Özkar, Saim (Wiley, 1997-12-05)
A kinetic study of the reaction between a hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) was carried out in the bulk state by using quantitative Fourier transform infrared(FTIR) spectroscopy. The reaction is shown to obey a second-order rate law, being first order in both the HTPB and IPDI concentrations. The activation parameters obtained from the evaluation of kinetic data are Delta H-double dagger = 41.1 +/- 0.4 kJ mol, Delta S-double dagger = -198 +/- 2 J K-1 mol(-1) and E-a...

Koksel, Bahar; CİHANER, ATİLLA; Kaya, Murat; Volkan, Mürvet; Önal, Ahmet Muhtar (Wiley, 2008-05-15)
Conducting polymers containing polyether pseudocages (PI, PII, PIII) have been synthesized via chemical oxidation of 1,5-bis(1,1-pyrrole)-3-oxabutane (MI), 1,8-bis(I,I-pyrrole)-3,6-dioxahexane (MII), and 1,11-bis(1,1-pyrrole)-3,6,9-trioxaundecane (MIII) using anhydrous FeCl3 in CHCl3. Because as obtained polymer resins did not give any response toward any cations, they were reduced (undoped) using chemical reducing agents. Tetrabutylammonium hydroxide was found to be more effective in undoping to obtain mor...
Synthesis of ferrocenyl quinolines
Zora, Metin (Elsevier BV, 2008-06-01)
A convenient one-pot synthesis of ferrocenyl-substituted quinolines via a molecular iodine-catalyzed reaction of ferrocenylimines with enolizable aldehydes is reported. First, nucleophilic addition of the in situ generated enol to ferrocenylimine produces beta-anilinopropionaldehyde, which then undergoes intramolecular Friedel-Crafts reaction to give dihydroquinoline derivative. Finally, subsequent dehydration and aerobic oxidation affords ferrocenyl quinolines.
