Structural transformations and solid-state reactivity involving nano lead(II) coordination polymers via thermal, mechanochemical and photochemical approaches

Advances in Solid-State Transformations of Coordination Bonds: From the Ball Mill to the Aging Chamber

“…Although the ability to induce transformations of solids by grinding or milling has been known for millennia [ 55 ], only recently has it been validated as a versatile method to conduct organic [ 56 , 57 ], inorganic [ 58 ], and organometallic [ 59 , 60 ] transformations leading to diverse high-value materials, including pharmaceuticals [ 61 , 62 ], nanoparticles [ 63 , 64 ], hybrid [ 65 ] and microporous materials [ 66 , 67 , 68 ]. Solid-state chemistry appears particularly amenable to the self-assembly of complex structures, through hydrogen bonding, reversible covalent chemistry or formation of coordination bonds, with a large array of literature examples demonstrating the synthesis of small molecule complexes [ 1 , 69 ], (supra)molecular or metal-organic clusters and cages [ 70 , 71 , 72 ], as well as coordination polymers [ 73 , 74 , 75 ]. Inspired by such work, several pioneering reports have demonstrated that not only is the solid-state synthesis of MOFs feasible, but that it can be faster and higher yielding than many alternatives [ 76 ].…”

Structural conversion of three copper(ii) complexes with snapshot observations based on the different crystal colours and morphology

“…The structural transformation of complexes can lead to different properties, such as colour, morphology, adsorption, chirality, luminescence and magnetism. [1][2][3][4][5][6][7][8][9][10][11][12][13] The potential application value brought by the diversity of complex structures has attracted more and more attention. 14 The structural transformation is usually characterized by small changes in the number and order of uncoordinated molecules at the molecular level, such as the addition and removal of solvents or guest molecules.…”

Solvent-mediated structural transformations of copper(II) coordination polymers induced by different short-chain alcohols

“…Compared with brittleness in the conventional crystalline materials, the dynamic CPs normally exhibit flexible property upon external stimuli, such as solvent, temperature, counterion, pressure and light (Fairen-Jimenez et al, 2011;Graham et al, 2011;Desai et al, 2016;Hobday et al, 2016;McKellar et al, 2016;Mon et al, 2016;Ye et al, 2017). During these processes, reactions are generally involved in the destruction/construction of covalent or noncovalent interactions, by tuning the local binding features of individual ingredients and then fulfilling the overall structural extension/ stacking in the crystalline state ( Usually, such processes seem to be difficult to control and understand (Bennett et al, 2015;Aboutorabi & Morsali, 2016). Of further significance, such reactions can produce some targeted compounds which cannot be synthesized in a routine approach.…”
