WebbDiscusses the different terms of abundance, species richness, and diversity and how to calculate Shannon diversity index. Note: there is a miscalculation in ... WebbHighly fused, fully conjugated aromatic compounds are interesting candidates for organic electronics. With higher crystallinity their electronic properties improve. It is shown here that the crystallization of three archetypes of such molecules-pentacenetetrone, indigo, and perinone-can be achieved hydrothermally.
