Supramolecular interactions in a 1:1 co-crystal of acridine and 3-chlorothiophene-2-carboxylic acid

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
In the title co-crystal, C5H3ClO2S·C13H9N, the components interact with each other via an O—H...N hydrogen bond. Acridine–acridine stacking, thiophene–thiophene stacking and acridine–thiophene C—H...π interactions also occur in the crystal.

Monte Carlo algorithm based on internal bridging moves for the atomistic simulation of thiophene oligomers and polymers

open access: yes, 2018
We introduce a powerful Monte Carlo (MC) algorithm for the atomistic simulation of bulk models of oligo- and poly-thiophenes by redesigning MC moves originally developed for considerably simpler polymer structures and architectures, such as linear and ...
