论文摘要
合成了新型的双功能纤维素二乙酸酯衍生物，以实现基于生物的光蛋白毒剂，可以通过直接激光写入（DLW）通过两光子吸收来构建，而无需使用光启动剂。因此，糖二酸纤维素通过硫醇部分和烯烃或甲基丙烯酸侧组功能化，从而实现硫醇偶联的交联。这些纤维素衍生物也可以通过紫外线照射（$λ$ = 254 nm和365 nm）进行光合链接，而无需使用启动器。
Novel bifunctional cellulose diacetate derivatives were synthesized in order to achieve bio-based photoresists, which can be structured by two-photon absorption via direct laser writing (DLW) without the need to use a photoinitiator. Therefore, cellulose diacetate is functionalized with thiol moieties and olefinic or methacrylic side groups enabling thiol-conjugated crosslinking. These cellulose derivatives are also photo-crosslinkable via UV irradiation ($λ$ = 254 nm and 365 nm) without using an initiator.
