Carbon-centred chirality of the pincer-type cyclometalated ligands is transferred to the helical chirality of dinuclear and tetranuclear Pd(II) arylacetylide complexes, and hence phosphorescence with quantum yields up to 50% and dissymmetry factors in the 10⁻³ scale from the metal–metal-to-ligand charge-transfer excited states has been recorded in diluted solutions.

分子内具有Pd⋯Pd嗜金属性的螺旋手性Pd（II）配合物，为圆极化分子磷

钳型环金属化配体的以碳为中心的手性转移到双核和四核Pd（II）芳基乙炔配合物的螺旋手性，因此磷光的量子产率高达50％，且金属的不对称因子为10 ^-3 –在稀释溶液中记录了金属到配体的电荷转移激发态。
