General information

Name of the project: Micromolecular engineering of block copolymer nanocomposites for applications as phonon-photon zone materials with high efficiency of conductivity

Goals and objectives

Project objective: Usage of the process of hierarchical self-assembly of block copolymers for creation of materials that will be produced i the form of functional films for later heterogeneous integration

The practical value of the study

Scientific results:

  1. Within the project, we have synthesized and researched conjugated donor-acceptor D-A polymers that have wide intervals of variation of number-average molecular weight (Mn). 
  2. Our research demonstrates that 2,3-diphenylquinoxaline links in combination with IDT donor groups form wide-band-gap polymers. In this work we found that PIDTTQ with high molecular weight (PIDTTQ-HMW) ensure a higher photo-electric current, fill factor and efficiency thanks to improved light absorption and charge carrier transport properties and lower losses on non-radiative recombination.
  3. We have created a new approach to producing nanocomposite materials with the use of sequential anionic polymerization and post-synthetic etherification reactions with chemically modified graphene sheets (CMG). Anionically synthesized precursors of diblock copolymers of the PS-b-PI-OH type were grafted to chemically modified groups –COOH CMG, which resulted in the production of output composite materials, namely polystyrene-b-poly(isoprene)-g-CMG, which manifested improved physical and chemical properties. 
  4. The successful synthesis was confirmed using several methods of molecular characterization together with thermogravimetric analysis to check the increased thermal stability, while the structure-properties relation was researched using transmission electron microscopy (TEM). 
  5. We have studied the locations of CMG in the structure for the cases of formation of lamellar and cylindrical morphologies.
  6. Magnetic nanoparticles with a diameter of 10 nm have been synthesized by coprecipitation. A mixture of 8,6 g of FeCl3·6H2O and 3,1 g of FeCl2·4H2O was dispersed in 25 ml of water Mili Q-grade and treated with ultrasound for 1 hour. Iron oxide maghemite nanoparticles (γ-Fe2O3) with a diameter of 10-11 nm were modified with the use of chlorosilane chemistry. The morphological characterization was conducted using TEM and atomic force microscopy (AFM). We demonstrated the regular distribution of nanoparticles in the polymer matrix.
  7. It has been demonstrated that planar conformation of conjugated polymer chains is necessary to achieve high mobility of charge carriers along the direction of molecular π-π stacking, but is often accompanied by poor charge transfer in other directions. This is especially true for molecules functionalized with alkyl chains that provide good technological effectiveness (solubility), but create isolating regions in the structure. In our work we demonstrated that soluble flat dumbbell-like molecule consisting of two triazatruxene (ТАТ) links that are covalently bound with the central segment of thiophene-tienopyrroldiol-thiophene (TPD), self-assemble into the initial structure that ensures efficient three-dimensional charge transport. Wide-angle scattering of X-rays in a sliding beam geometry, as well as micro-focus X-ray experiments on monocrystals demonstrate that derivatives of ТАТ form a columnar nematic mesophase in which columns of stocked ТАТ units, separated by liquid-like alkyl chains, are connected with TPD bridges. During annealing, a crystalline phase is formed that emerges from the initial hexagonal mesophase with a direction of molecular packaging that lies in the plane of the substrate. Changes of transport in the crystalline phase caused unusually mobility of holes outside of the plane amounting to 0,17 cm2/V×s and a lower bound of in-plane mobility of 0,05 cm2/V×s. The results indicate that TPD segments that connect neighboring stacks of TAT columns are responsible for efficient hole transport in 3D.
