Abstract
Covalent organic frameworks (COFs) emerged as promising porous, crystalline materials that found various many applications in various fields. The proposed project focuses on the obtaining and characterization of COFs and Metal@COF (Me@COF) hybrid materials designed for innovative applications in heterogenous catalysis, chiral separations and active materials in state-of-the-art Single Material Organic Solar Cells (SMOSCs). The strengths of the proposal rely on the careful design of the targeted materials. Therefore, versatile building blocks of various geometries are used to give access to a plethora of 3D achiral and chiral COFs and Me@COFs with modulable pore size to act as catalysts and asymmetric catalysts for various cross-coupling reactions. The main advantage of the proposed materials is the direct access to Me@COF hybrid materials by coupling reactions (i.e. Suzuki-Miyaura, Sonogashira, Glaser), thus incorporating in the COF structure the metal used as a catalyst in their synthesis. In addition, macrocycles- and cryptand-based COFs and Me@COFs bearing different types of cavities and catalytic site will be obtained and tested as multifunctional catalysts for reaction carried out sequentially or in cascade. Furthermore, taking advantage of highly ordered COFs structures we propose 2D frameworks that display efficient segregation of the donor and acceptor units, a requirement in the fabrication of highly efficient and stable SMOSCs.

Description
Activity 1.1. Synthesis and characterization of building blocks.
The design and synthesis of tetrahedral (4 types), tetragonal (3 types), trigonal (4 types) and digonal (3 types) building blocks for COFs dedicated to applications in catalysis and for SMOSCs were performed. The 14 building blocks were characterized by NMR and MS spectra.
Activity 1.2. Elaboration of the procedures for the access to COFs and hybrid Me@COF materials for catalysis and for the access to SMOSCs.
Three COFs were obtained by a DCC method based on imine formation reactions. The method was solvothermal and the optimal conditions were found by varying the solvents, temperature and reaction time. The COFs were dopped with Pd(OAc)2 in DCM and then Pd(2+) was reduced to Pd(0) resulting hybrid Me@COF materials which were used successfully to catalyze Suzuki-Miyaura cross coupling reactions. An exciting COF was obtained via boronic ester type connections and this COF catalyzed the click reaction in a purely metal free process.

Description
Activity 2.1. Synthesis and characterization of building blocks (continuation of stage 1)
The design and synthesis of tetrahedral (2 types), tetragonal (2 types), trigonal (3 types) and digonal (4 types) building blocks for COFs dedicated to applications in catalysis and for SMOSCs. The 11 building blocks were characterized by NMR and MS spectra. It is to underline the obtaining of the chiral BB (S configuration); a di-yne of binaphthyl which was used for the access to Pd@Cu@PAF-CHIR1 hybrid material.
Activity 2.2. Synthesis, characterization and investigation of catalytical activity of COFs and hybrid Me@COF materials designed for heterogenous catalysis
The one-step synthesis of three hybrid Pd@Cu@PAF materials by the Sonogashira cross-coupling reaction starting from tetrahalogenated tetrahedral (or pseudotetrahedral) substrates and aromatic di-ynes were successfully carried out. The hybrid Pd@Cu@PAF materials were powerful multifunctional catalysts for Suzuki-Miyaura and Sonogashira cross-coupling and „click” reactions, as well as for one-pot “click”-Sonogashira procedures. COFs and PAFs (Porous Aromatic Frameworks; the differences between COFs and PAFs are due to the higher crystallinity of COFs) were characterized by specific measurements (TEM, XPR, BET) and for the catalytic studies were elaborated specific procedures.
Activity 2.3. Synthesis, characterization and investigation of photovoltaic activity of 2D COFs designed for the access to SMOSCs.
Two COF-OSCs were obtained by Knoevenagel condensation reactions. These COFs include donor and acceptor units in their structures. The SMOSCs obtained with these COFs revealed remarkable efficiencies for such materials (unexplored). 2D COFs were characterized by specific measurements (TEM, XPR, BET) and for the fabrication of SMOSCs were elaborated specific procedures.
