Supramolecular assemblies of copper(II) complexes: supramolecular synthon transferability and magnetic properties [PDF]
Acta Crystallographica Section A Foundations and Advances, 2019 In the pursuit of new technologies there is exigency for novel materials with desired physical and chemical properties. Despite the fact that metal-based crystalline solids provide an access to properties that are typically unavailable or difficult to achieve in metal-free settings (i.e. magnetic or optical).

Control Strategies in Guanine Biocrystallization
Angewandte Chemie International Edition, EarlyView.Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...
