In 2022,Lu, Shaoyong; Fu, Zhong; Li, Fu; Weng, Kangkang; Zhou, Likuan; Zhang, Lipeng; Yang, Yuchen; Qiu, Hengwei; Liu, Dan; Qing, Wenyue; Ding, He; Sheng, Xing; Chen, Menglu; Tang, Xin; Duan, Lian; Liu, Wenyong; Wu, Longjia; Yang, Yixing; Zhang, Hao; Li, Jinghong published an article in Angewandte Chemie, International Edition. The title of the article was 《Beyond a Linker: The Role of Photochemistry of Crosslinkers in the Direct Optical Patterning of Colloidal Nanocrystals》.Electric Literature of C6H11NO The author mentioned the following in the article:
Surface chem. mediated direct optical patterning represents an emerging strategy for incorporating colloidal nanocrystals (NCs) in integrated optoelectronic platforms including displays and image sensors. However, the role of photochem. of crosslinkers and other photoactive species in patterning remains elusive. Here we show the design of nitrene- and carbene-based photocrosslinkers can strongly affect the patterning capabilities and photophys. properties of NCs, especially quantum dots (QDs). Their role beyond phys. linkers stems from structure-dictated electronic configuration, energy alignment and associated reaction kinetics and thermodn. Patterned QD layers with designed carbene-based crosslinkers fully preserve their photoluminescent and electroluminescent properties. Patterned light emitting diodes (QLEDs) show a maximum external quantum efficiency of ∼12 % and lifetime over 4800 h, among the highest for reported patterned QLEDs. These results would guide the rational design of photoactive species in NC patterning and create new possibilities in the monolithic integration of NCs in high-performance device platforms. The experimental part of the paper was very detailed, including the reaction process of 1-Methyl-4-piperidone(cas: 1445-73-4Electric Literature of C6H11NO)
1-Methyl-4-piperidone(cas: 1445-73-4) is a member of piperidine. Piperidine is ubiquitous structural motif widely occurred in diverse synthetically and naturally occurring bioactive molecules. Piperidines are an immensely important class of compounds medicinally: the piperidine ring is the most common heterocyclic subunit among FDA approved drugs.Electric Literature of C6H11NO
