“…Vapochromism and vapoluminescence in coordination complexes is possible through a variety of different mechanisms. Changes in metal-metal interactions play an important role in many platinum(II) and gold(I) based substances, 13,14,17,35,37,36,50,41,66,67,68,69,70,72,73,88,91,92,93,95,97,98,99,100,102,105,106,116,117,118,121,129,128,135,144,146,148,149,156,155,158,157,160,164,212 and modifications in π-π stacking are relatively widespread as well. 59,88,91,93,…”

“…ZrP has been used for the intercalation of several photo-, bio-and redox-active compounds for a wide variety of applications including artificial photosynthesis, amperometric biosensors, and drug delivery [27,[30][31][32][33][34][35][36][37][38][39][40][41][42]. Even though ZrP has previously been studied for catalysis [43][44][45][46][47], membrane composites for proton exchange water electrolyzers [48][49][50][51][52], and as additive for catalytic layers for OER in order to protect metal oxide catalysts [53], our work is, to the best of our knowledge, the first time ZrP is used as an inorganic support for catalysts for the OER.…”

The conversion of solar energy into chemical fuel is one of the "Holy Grails" of twenty-first century chemistry. Solar energy can be used to split water into oxygen and protons, which are then used to make hydrogen fuel. Nature is able to catalyze both the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) required for the conversion of solar energy into chemical fuel through the employment of enzymes that are composed of inexpensive transition metals. Instead of using expensive catalysts such as platinum, cheaper alternatives (such as cobalt, iron, or nickel) would provide the opportunity to make solar energy competitive with fossil fuels. However, obtaining efficient catalysts based on earthabundant materials is still a daunting task. In this chapter, we review the advancements made with zirconium phosphate (ZrP) as a support for earth-abundant transition metals for the OER. Our studies have found that ZrP is a suitable support for transition metals as it provides an accessible surface where the OER can occur. Further findings have also shown that exfoliation of ZrP increases the availability of sites where active species can be adsorbed and performance is improved with this strategy.

“…[67][68][69][70] However, it is well-known that the optoelectronic properties of metal complexes can be impacted by their microenvironment, as in the case of vapochromic materials composed of luminescent platinum(II) complexes intercalated into zirconium phosphate layered materials which are non-emissive in solution and highly emissive in the ZrP layers. 71 The majority of work on polymers embedded with platinum(II) complexes has focused on using Nafion to develop efficient singlet oxygen photosensitizers; however less attention has been given to the spectroscopic properties of these materials. 70,72,73 In one study, it was found that incorporation of non-emissive Pt(2,2 0 :6 0 ,2 00 :6 00 ,2 000 -quaterpyridine) 2+ complexes into inverse micelles of water swollen Nafion produced strongly luminescent materials resulting from increased concentration and intermolecular interactions of the complexes.…”

Square-planar platinum(II) complexes of the 4-dodecyloxy-2,6-bis(N-methylbenzimidazol-2 0 -yl) pyridine ligand have been blended into a series of methacrylate polymers. Each of the polymer films displayed vapochromic (yellow to red) and vapoluminescent behaviour as a result of the vapour induced change in the Pt-Pt interactions. The solid-state absorption and emission properties of the films were characterized, and the influence of the polymer matrix on the vapochromic response was investigated. Notably, the rate of recovery of the yellow colour after vapour-exposure was found to be dependent on the T g of the matrices, and the response can be effectively erased and the materials restored to the original yellow colour within minutes by simply heating above their T g . The polymer-complex blends also displayed interesting mechanochromic and mechanoluminescent properties upon deformation either by compression, scratching, or stretching. The accumulated data are consistent with a solvato-or mechanoinduced structural rearrangement that results in a shortening of the Pt-Pt distances.
