A series of luminescent polynuclear alkynylgold(I) complexes with different lengths of alkylchains attached at the N‐heterocyclic carbene moieties has been synthesised and demonstrated to display intriguing self‐assembly behaviours through a cooperative growth mechanism. Variation of the alkylchainlength was found to cause drastic morphological differences in the aggregates and to strongly affect

Benzodichalcogenophenes are functionalized at their termini via SNAr reactions of their bismetalates with perfluoroarenes. The identities of X, Y, and W are varied to study the effects on LUMO energy levels and crystallization motif. X-ray crystallography reveals that nearly all new derivatives crystallize with coplanar ring systems within slipped 1D or 2D pi-stacks.
