Three related aromatic [22] heteroporphyrins have been synthesized and characterized, with the target of achieving NIR absorption. The propensity of these smallest π-conjugated macrocycles to absorb in the NIR region is benefitted from the fusion/annelation of the precursor heterocycles.
以实现近红外吸收为目标,合成并鉴定了三种相关的芳香族 [22] 杂
卟啉。这些最小的 π 共轭大环在近红外区域的吸收倾向得益于前体杂环的融合/通道化。
