Hybrid solar cells based on conjugated polymers and inorganic semiconducting nanoparticles combine beneficial properties of organic and inorganic semiconductors and are, therefore, an exciting alternative to pure organic or inorganic solar cell technologies. Several approaches for the fabrication of hybrid solar cells are already elaborated and explored. In the last years routes have emerged, where the nanoparticles are prepared directly in the matrix of the conjugated polymer. Here, the conjugated polymer prevents the nanoparticles from excessive growth and thereby makes additional capping agents obsolete. This review focuses on in situ preparation methods of inorganic semiconducting nanoparticles in conjugated polymers in view of applications in hybrid solar cells. The details, advantages and disadvantages of the different in situ methods are critically examined and put in comparison to the classical route where pre-synthesized nanoparticles are used. Various key factors influencing the solar cell performance as well as future strategies for increasing the overall efficiency of hybrid solar cells prepared via in situ routes are discussed.

“…Further treatment of the film leads to nanoparticle growth at the embedded metal center seed points. Along with growth of the nanoparticles directly in the film, control of nanoparticle size has also been demonstrated, allowing us to tune the bandgaps of the incorporated nanoparticles [8][9][10][11][12][13]. The synthesis of the materials from a seeded growth method leads to an increase in interfacial communication between the two components (i.e., organic conducting polymer and inorganic semiconductor nanoparticle) which is key to exciton separation within and charge transport through this class of materials.…”

A variety of Schiff base ligands have been synthesized in an effort to study the coordination chemistry of these ligands when reacted with various metal salts. By varying the structural features of the ligand as well as the synthetic route used to make the corresponding metal complexes, a number of different structural motifs have been observed. Schiff base ligands were chosen due to their ease of synthesis as well as their ability to bind a variety of metal salts. These complexes serve as model systems for and precursors to monomers for the preparation of conducting metallopolymers. Further functionalization of the Schiff base ligand with bithiophene end groups has resulted in electropolymerizable monomers. When polymerized these monomers give conducting metallopolymers which can then be used for a variety of applications. The products were characterized by multinuclear NMR, UV-Vis, and IR spectroscopy, and mass spectrometry. Solid-state structures were determined by single crystal X-ray diffraction studies. Electropolymerization yielded novel conducting polymers with embedded metals.

“…This adsorbate was selected because of the possibility of spectrophotometric monitoring of the process, and also the potential possibility of its post-sorption conversion to copper(II) sulfide when treated with sulfide ions. The fruitfulness of such an approach was demonstrated recently when a composite material was obtained based on conductive organic polymers and cadmium sulfide nanoparticles [12].…”

We have established that crystalline nickel-containing metal-organic frameworks (MOFs) bind the complex [Cu(NH 3 ) 4 ](ClO 4 ) 2 from acetonitrile solutions and do not react with [Cu(en) 2 ](ClO 4 ) 2 .The MOF/copper ammine complex ratio in the products after reaching saturation is determined by the crystal lattice structures of the compounds, and increases from 1.2 (one-dimensional coordination polymer, 1D CP) to 3.2 (2D CP) and 3.9 (ionic MOF) moles of copper ammine complex per formula unit of sorbent. We have shown that it is possible to convert the bound ammine complex to nanosized copper(II) sulfide by treatment with sodium sulfide.The increased interest displayed recently in "metal-organic frameworks" (MOFs), which are porous crystalline materials constructed on the basis of metal complex compounds, is mainly due to their specific sorption characteristics relative to gases or vapors of organic compounds [1][2][3][4]. At the same time, binding by these materials of molecules with a more complicated structure (in particular, metal complex species) has been significantly less studied, although in our opinion, determining the behavior of such processes is an important problem. On the one hand, we can expect high selectivity in such reactions, based on the principles of molecular recognition (geometric match between the sizes of the adsorbate (Ads) and the pores in the MOF, spatial complementarity between the interacting reagent centers). On the other hand, subsequent chemical conversions of the adsorbates in [MOFÌAds] complexes may be a convenient method for obtaining new composite materials having valuable properties.As an example, we can give the reactions of sorption from the gas phase of volatile organometallic compounds of the cyclopentadienyl type or acetylacetonate complexes of transition metals, followed by their subsequent reduction down to the metals [5,6]. Such an approach made it possible to obtain new composite catalysts containing nanoclusters of metals, dispersed in a sorbent matrix [7]. Several papers have also been published that are devoted to the study of sorption processes in (crystalline sorbent (MOF))/(solution containing nonvolatile metal-containing compounds) systems, where the nonvolatile compounds include in particular HgCl 2 [8] or [Cu(NH 3 ) 4 ](ClO 4 ) 2 [9][10][11]. For the latter adsorbate, it has been shown that reactions with participation of nickel-containing MOFs occur with retention of the crystal lattice of the sorbent [9, 10], while in 58 0040-5760/10/4601-0058
