手性双环酰肼有机催化剂先前已被证明能够以高对映选择性催化 ( Z )-多烯底物的环化,但对相应的 ( E )-多烯的选择性较差。在这里,我们证明带有三联苯的二氮杂烷羧酸酯能够有效催化(E)-多烯双环化,其对映选择性高达 94:6 er,并且对反式十氢萘形成具有高非对映选择性。该催化剂通过亚胺离子形成同时引发环化并通过阳离子-π相互作用稳定中间体/过渡态来发挥作用。

A negative chemically amplified photoresist of a fused ring aromatic hydrocarbon derivative, a preparation method therefor, and use thereof are provided. A matrix component in the photoresist is a fused ring aromatic hydrocarbon derivative represented by general formula (I) that can be dissolved in organic solvents commonly used in photoresists. The photoresist composition of the present disclosure can be prepared to give a uniform film, and a molecular glass serving as the matrix component is not precipitated in the film preparation process.
