Design and synthesis of new ruthenium complex for dye-sensitized solar cells

A series of ruthenium complexes (MC-1-MC-3), incorporated with carbazole, fluorene and phenothiazine units with dipyrido[3,2-a:2′,3′-c]phenazine are synthesized, characterized and their optical, electrochemical and photovoltaic properties are investigated. The observed differences in light-harvesting ability of the sensitizers are associated with the electron donor strength of the ancillary ligand used for preparing complexes. The dye-sensitized solar cell fabricated from complex MC-1 exhibited a power conversion efficiency of 6.18%. It is demonstrated that new molecular design and increase in molar absorption coefficient of the sensitizer improved the device performance.

Structure-properties relationship of the derivatives of carbazole and 1,8-naphthalimide: Effects of the substitution and the linking topology

Nine compounds having electron-accepting 1,8-naphthalimide and electron-donating carbazole moieties were synthesized employing palladium-catalyzed C-N and C-C coupling reactions and characterized by the thermal methods, absorption and emission spectrometry, electrochemical and photoelectrical tools. The synthesized compounds possess high thermal stability with the 5% weight loss temperatures being in the range of 351-476 °C. Most of the synthesized compounds are capable of glass formation with glass transition temperatures ranging from 30 to 87 °C. The cyclic voltammetry measurements showed that the solid state ionization potentials values of the carbazole and 1,8-naphthalimide derivatives range from 5.46 eV to 5.76 eV and the electron affinities values range from -3.04 eV to -2.92 eV. Dilute solutions of the 3- and 3,6-naphthalimide-substituted derivatives of carbazole in polar solvents were found to emit in the green region with quantum yields ranging from 0.66 to 0.83, while in the solid state fluorescence quantum yields were found to be in the range of 0.01-0.45. ((E)-9-(((N-(2-ethylhexyl)-1,8-naphthalimide)-4-yl)ethenyl)-9H-carbazole) exhibited efficient fluorescence in the solid state with quantum yield as high as 0.45. The effects of the linking topology of the chromophores and of the incorporated alkyl substituents on the thermal, optical, and photoelectrical properties of the synthesized donor-acceptor compounds are analyzed. The impact of the ground state intramolecular twisting of the carbazole and naphthalimide moieties induced by the substituents resulting in significant variation in the rates of radiative and nonradiative excitation deactivation is revealed.
