Two 1,1,4,4-tetracyanobutadiene (TCBD) derivatives were prepared by [2+2]cycloaddition-retroelectrocyclization from ynamides bearing either a pyrene (1) or a perylene unit (2). In addition to panchromatic absorptions in 2, in the solid state, both compounds unexpectedly display NIR photoluminescence that could be detected up to about 1350 nm.
通过[2+2]环加成-逆电环化反应，由带有芘（1）或苝单元（2）的炔酰胺制备了两种1,1,4,4-四氰基丁二烯（TCBD）衍生物。除了2中的全色吸收外，在固态下，这两种化合物意外地都显示出近红外光致发光，其可检测到约1350nm。
