Synthesis and properties of the conjugated polymers with indenoindene and benzimidazole units for organic photovoltaics

A new electron deficient unit, dimethyl-2H-benzimidazole (MBI), and dihydroindeno[2,1-a]indene (ININE) moiety as electron-rich unit were coupled to synthesize the conjugated polymers containing electron donor-acceptor pair for organic photovoltaics. ININE, MBI, and thiophene (or bithiophene) units were incorporated using Stille and Suzuki polymerization to generate poly(2,7-(5,5,10,10-tetrakis(2-ethylhexyl)-5,10-dihydro- indeno[2,1-a]indene)- alt-5,5-(4′,7′-di-2-thienyl-2,2-dimethyl-2H-benzimidazole)) (PININEDTMBIs) (or PININEBBTMBIs). In MBI, the sulfur at 2-position of 2,1,3-benzothiadiazole (BT) unit was replaced with dialkyl-substituted carbon, whereas keeping the 1,2-quinoid form, to improve the solubility of the polymers. The field-effect hole mobility of PININEBBTMBI was 3.2 × 10-4 cm2/Vs which was improved as compared to that of PININEDTMBI (2.7 × 10-5 cm2/Vs) caused by the introduction of bithiophene units. In case of the most efficient polymer, PININEBBTMBI, the device with the configuration of indium tin oxide (ITO)/poly(3,4- ethylenedioxythiophene) (PEDOT):polystyrene sulfonate (PSS)/polymer:PC 71BM(1:4 w/w)/Al, annealed at 100 C for 10 min demonstrated a open circuit voltage of 0.78 V, a short-circuit current density of 6.66 mA/cm 2, and a fill factor of 0.41, leading to the power conversion efficiency of 2.11%, under white-light illumination (AM 1.5 G, 100 mW/cm 2).

A Case of Fully Diffusion-Controlled Exothermic Triplet Excitation Transfer

Conventional flash kinetic spectroscopy has been used to determine rate constants (kobsd) for triplet energy transfer from indenoindene, a rigid model of trans-stilbene, to azulene as a function of temperature in n-pentane (228 - 290 K), toluene (228 - 309 K), acetonitrile (233 - 308 K), and tert-butyl alcohol (302 - 342 K).In toluene the plot of kobsd vs.T/η is linear with a slope somewhat smaller than predicted by the Debye equation for a diffusion-controlled process.In n-pentane the plot shows upward curvature, while in tert-butyl alcohol and in acetonitrile the T/η plots show downward curvature.The possibility that the downward curvature is due to deviation from a fully diffusion-controlled process is examined but rejected following a critical comparison of kobsd with recently reported termination rate constants for coupling and disproportionation of tert-butyl radicals, kt.The kobsd/kt ratios for the entire temperature and solvent range, 3.1 - 4.5, are consistent with the spin-statistical factor φ = 1/4, proposed as the sole deviation of kt from a fully diffusion-controlled rate constant.Empirically based truncated microfriction factors were used to correct diffusion coefficients in the nonhydroxylic solvents, and calculated values of φ-1, falling in the 3.5 - 5.0 range, were obtained that were indistinguishable from 4 within the experimental uncertainties of the measurements.It is concluded that excitation transfer is fully diffusion controlled under all conditions employed here and that, following an encounter between donor and acceptor, a probable lower limit for the rate constant of excitation transfer is ket (*) 2*1012 s-1.This result is compared with observations in the literature.Satisfactory adherence to the Arrhenius equation is observed in all four solvents and activation energies are similar to activation energies for viscous flow obtained from the temperature dependence of η using the Andrade equation.Entropies and enthalpies of activation, obtained by applying transition-state theory to kobsd and 4kt, obey a common isokinetic relationship, with β = 372 K as the isokinetic temperature.This isokinetic relationship is likely to apply to related diffusion-controlled reactions.Activation entropies, (*), are compared to cratic entropies, ΔSc, for the reversible formation of an encounter complex.Except for tert-butyl alcohol, where (*) ca. 0, (*) is roughly 4/3ΔSc reflecting more ordering in the transition state than in the fully formed encounter complex.
