A fast-response photochromic host–guest coordination polymer with a close-packed stacking structure

A photochromic phenyl-substituted viologen based derivative that is embedded in a layered zinc–carboxylate framework is shown to have a fast photoswitching behavior. A favorable geometry for intermolecular electron transfer is established by the sandwich-type π–π stacking structure between the photoactive host and guest components.

Mechanical path to a photogenerated structure: ball milling-induced phase transition of a gold(I) complex

Ball milling of blue-emitting crystal 1B of gold(I) isocyanide complex 1 induces a phase transition to yellow-emitting powder 1YG, which has the same solid structure as the previously reported 1Y obtained upon photoirradiation of 1B.

Effect of crystal packing on the excitonic properties of rubrene polymorphs

Singlet fission (SF), the conversion of one singlet exciton into two triplet excitons, may increase the efficiency of organic photovoltaics by generating two carriers from one photon. Based on first-principles simulations, the monoclinic form of rubrene is expected to exhibit higher SF efficiency than the orthorhombic form.

1,2,4-Triazole-based molecular switches: crystal structures, Hirshfeld surface analysis and optical properties

A series of eight closely related N-salicylidene-4-amino-1,2,4-triazole compounds has been prepared. Their crystal structures were elucidated by single-crystal X-ray diffraction and optical properties were examined by diffuse reflectance spectroscopy. Noncovalent interactions detected in these compounds were, for the first time, analyzed by means of Hirshfeld surface analysis.
