The single crystals of a butterfly‐shaped carbonyl‐bridged twistarene 3 were obtained by slow diffusion of methanol into its chloroform solution. The single‐crystal structure analysis indicated that 3 crystallized in a triclinic space group (P‐1). The two‐photon absorption (TPA) and nonlinear optical properties of single crystal of 3 were investigated in the range of 400 nm ∼650 nm. This is the first example of the TPA study based on single crystals made from the carbonyl‐bridged twistarene. The corresponding TPA cross‐section was found to be 3.69 GM at 800 nm.

蝶型羰基桥联芳纶的双光子吸收
蝴蝶形羰基桥联芳纶3的单晶是通过将甲醇缓慢扩散到其氯仿溶液中而获得的。单晶结构分析表明3在三斜晶空间群（P-1）中结晶。研究了3个单晶在400 nm〜650 nm范围内的双光子吸收（TPA）和非线性光学性质。这是TPA研究的第一个例子，该研究基于由羰基桥联的芳纶制成的单晶。发现对应的TPA横截面在800 nm为3.69 GM。
