Bis(4-cyano-1-pyridino)pentane halobismuthates. Light-harvesting material with an optical band gap of 1.59 eV

https://doi.org/10.1016/j.mencom.2017.05.018Get rights and content

A new organic-inorganic hybrid material composed of 0-D bromobismuthate anions and bis(4-cyano-1-pyridino)pentane cations was synthesized and characterized. The replacement of Br with I resulted in a decrease in the optical band gap from 2.88 eV for (C17H18N4)2Bi2Br10 to 1.59 eV for (C17H18N4)BiI5. Thus, (C17H18N4)BiI5 can be proposed as a candidate material for solid state solar cells.

    Hybrid halobismuthates are of particular interest since a wide variety of their physical properties, such as luminescence, thermochromism, unusual magnetic properties and potential photovoltaic applications [1–9]. In our earlier studies [10–12] we showed that some of hybrid halobismuthates have low optical band gap values and can be promising candidates for light-harvesting materials for optoelectronic devices. We isolated and structurally characterised 1,1’-(alkane-1,1′-diyl)bis (2-aminopyridinium) bromobismuthate and 1,1’-(alkane-1,1′-diyl)bis (4-aminopyridinium) bromobismuthate [13] from a strongly acidic medium (concentrated HBr), but for none of these compounds the protonation of amino groups was observed.

    The 1,1'-(1,5-pentanediyl)bis(4-methylpyridinium) cation in this compound consists of two picoline fragments connected by a pentane chain. There are more than 20 hybrid bromobismuthates based on such dications, which consist of two identical fragments, connected by alkyl chain [16–28]. The xylylene fragment and the pentane chain are of similar length, therefore we assumed that halobismuthates of divalent cations containing xylylene fragment as a spacer may also possess interesting optical properties, like the compound studied previously [13].

    Among those, there are photochromism occurring in viologen salts [3–5], thermochromism [6,7], ferroelectricity and ferroelasticity [8–12], unusual color changes induced by surface interaction with solvent [13], photocatalytic activity [14–18] etc. Besides, halometalates demonstrate extraordinary structural diversity: they can reach nuclearity of up to 8 Bi (in discrete anions) [19–28], as well as form various polymers [29–34], making them interesting objects in terms of structural chemistry. Within the last years, the special interest has been focused on the studies related to their use in photovoltaic (so-called “perovskite-type”) devices.

    On the other hand, the price for the simplicity is extreme difficulty (or even impossibility) of making any reliable predictions about the structure of a particular complex forming under certain conditions. Depending on the nature of metal, p-block elements form discrete polynuclear halide complexes of different nuclearity (up to 8 for Bi(III) [16–18] or 18 for Pb(II) [19]), as well as one-, two- or three-dimensional polymers [15,20–24]. Usually, such reactions cannot be reliably controlled stoichiometrically; the key factors governing the structure and composition of resulting halometalates are the nature and geometry of counter cations and, in some cases, the solvent.15 In particular, Benetollo et al. have shown [25] that reaction between Bi2O3 and N-heterocyclic bases in HCl solutions may result both in [BiCl6]3− and binuclear [Bi2Cl10]4− in the case of 8-hydroxyquinolinium and quinolinium or isoquinolinium, respectively [25].
