Synthesis of Novel Porphyrin and its Complexes Covalently Linked to Multi-Walled Carbon Nanotubes and Study of their Spectroscopy
Novel covalent porphyrin and its complexes (Co(2+), Zn(2+)) functionalized multi-walled carbon nanotubes (MWNTs) have been successfully synthesized by the reaction of the carboxyl on the surface of MWNTs which was synthesized to use carbon radicals generated by the thermal decomposition of azodiisobutyronitrile (AIBN) with 5-p-hydroxyphenyl-10,15,20-triphenyl-porphyrin and its complexes (Co(2+)...
متن کاملCarbon nanotubes with covalently linked porphyrin antennae: photoinduced electron transfer.
Single- and multiwalled carbon nanotubes have been covalently functionalized with free-base porphyrin. The quantity of porphyrin linked to the surface was determined from thermogravimetric and UV-vis analysis. A reversible protonation equilibrium between the attached porphyrin and the residual acid groups of the carbon nanotubes has been identified. Steady-state fluorescence emission spectrum o...
متن کاملEffects of fullerene encapsulation on structure and photophysical properties of porphyrin-linked single-walled carbon nanotubes.
Fullerene-encapsulating single-walled carbon nanotubes (C(60)@SWNT) linked with porphyrins by a short bridge have been prepared for the first time. Steady state and time-resolved spectroscopies demonstrated the initial formation of an exciplex state, followed by a charge-separated state.
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولSynthesis of Some New Disperse Dyes-multi Walled Carbon Nanotubes Adducts and Impact Analysis of Substituents
We have reported here a simple, low cost preparation of four new adducts from some anthraquinone disperse dyes with functionalized multi-walled carbon nanotubes in the presence of azochromophore. The structural differences between the final products are evaluated by visual dispersion test, UV-Vis Spectroscopy, Fourier transforms infrared, Raman, nuclear magnetic resonance and thermal gravimetri...
