Homoleptic gold(i) N-heterocyclic allenylidene complexes: excited-state properties and lyotropic chromonics†
Abstract
A series of phosphorescent Au(I) bis(N-heterocyclic allenylidene) complexes, namely [Au(CCCR1R2)2]+X−, were synthesized and structurally characterized. These organometallic complexes exhibit panchromatic transient absorption upon electronic photo-excitation and can self-organize into lyotropic chromonic mesophases in aqueous solutions.
